Sprint issue - Moto G4 Plus Questions & Answers

Sprint issue - Moto G4 Plus Questions & Answers

I've had my G4 Plus active on Sprint for around 8 days, and all of them I have had issues with receiving SMS messages. Sprint is currently saying that since it is an unlocked device, the support they can provide me is very limited. They can have me reset the network settings, to no avail. Does anyone here have a G4 Plus & Sprint? If so, what did you have to do to get it working?

I had Virgin Mobile with my Moto g3 which uses Sprint network and for connectivity issues they recommend doing PRL update. Otherwise did you check SIM settings? Cellular network settings? Very rarely I had issues with delayes in text messages when I was in Sprint network so I installed Push Notification Fixer app.

I have done a PRL & device config update. No SIM settings I can check or change, so far nothing has helped. However, with the reports from others where it has worked well I requested a replacement from Amazon to see if that will let me fix it.

To check SIM go to about phone-->status-->sim status. You can at least check network and rule that out.

Shows disconnected from the cell network. That is probably part of the issue I'm having.

I disconnected from WiFi and it showed connected. And I could receive text messages without issue. At this point, I think something is messed up with the phone and I am hoping the replacement works fine.

Got a new phone from Amazon and all is good now. Works great, I guess I just got a bum phone.

[Q] Nexus 4 data radio problem?

I'm a smartphone noob [though slightly above-average with technology in general] - the Nexus 4 is my first smartphone, and I've been lurking here for a week looking for all possible solutions for my problem and none have worked, so please bear with the longish post:
Nexus 4 16GB, bought from the US Play store - using it since Monday, Dec 10. I'm using it with a Straight Talk AT&T SIM, and I have *no cellular data* whatsoever. I have been using the phone for a week now, and I haven't been able to use the internet except on wifi. No 3G/EDGE/HSPA+ logos next to the signal bars - in fact the signal bars always grey when wifi is off. I have only seen the signal bars turn blue when the wifi is on, never on a cellular network.
APN settings have been verified, and tens (yes, TENS) of Straight Talk reps have said my account seems to be provisioned correctly and good to go. I have tried all the alternative APN settings suggested for Straight Talk on various forums, including the two-APN configuration for MMS and data, deleting the data proxy from the APN settings, reverting to the default APN settings on the SIM and even using the Straight Talk T-Mobile APN [though I know for sure mine is an AT&T SIM because T-Mo doesn't cover my workplace, where I have good signal strength].
My old device was an AT&T locked dumbphone, so I couldn't change the APN settings on it to use the data on StraightTalk, but when I put my Straight Talk SIM in, it shows the 3G logo next to the signal bars suggesting that my StraightTalk account is probably provisioned correctly for data.
Hard reset, repeated reboots and repeated toggling of data and airplane modes have all been tried, and nothing has changed the situation. I have perfect voice and text messaging connectivity and zero data.
As a smartphone noob - is there a separate radio in the phone for data connections, and is it possible that this radio alone is a lemon on my phone? I *do not* have access to another micro-SIM, unfortunately - CDMA is popular in my town and the only two of my friends who have phones with removable SIMs probably won't appreciate having their regular SIMs cut down to micro for me to test. Without being able to test it, I don't know if I should just RMA it either.
***UPDATE*** : FIXED
I got a T-Mobile SIM to test the phone, and data worked perfectly well on that, so I concluded it probably wasn't the phone. T-Mobile wasn't an option for me though, because they have crappy reception in most of my town.
Happened to travel to Boston, tried my StraightTalk SIM in a friend's phone there - data worked fine then. So now I didn't know if it was the phone or the SIM.
After three weeks of grief and fighting, I got StraightTalk to send me a replacement SIM, which fixed the issue immediately - I had full HSPA data connectivity within five minutes of dialing their number to have my SIM activated.

Turn on Mobile data?
Have you enabled the 3G/mobile data switch built into android? Settings > Wireless & data > More > Mobile Networks > data Enabled Tick that if its unchecked, Im still waiting for mine but my HTC explorer running a vanila flavour of ICS has a similar settings menu, its somewhere along those lines bud, post back with results. As i said might be in a different location due to the differing OS versions
Good luck mate, Blewk
EDIT: Nevermind ive just opened my eyes and noticed you've tried it xD
so try calling this number *#*#4636#*#* and going through each of those settings (apart from LTE of course) see if any of them give you a Data connection. constantly checking the data switch on the phone at all times though making sure its enabled If this offers no luck im out of ideas for you mate

Thank you, but I have done that too. That isn't restoring connectivity.

So what are your APN setting? Can't really trust CSRs since they aren't using a Nexus 4 to test themselves.

I've attached screenshots with the current settings, which are the ones the CSRs recommended.
I have also tried
deleting the proxy+port
changing both proxies to addressort format
changing the APN type to "default,supl,mms".
editing the SIM's default APN values to these, instead of creating a new APN.
and various combinations of these. None of these have helped. (I reboot and wait 30-45 minutes after every change in these settings).
EDIT: addressort is address(colon)port. Forgot to disable smilies.

Try changing your MMS Proxy to 66.209.11.33 see if that helps. Its the only difference I can see.

Thank you, I've tried that too. Since my other phone (without the correct APN) still shows the 3G logo next to the signal bars and the Nexus 4 doesn't show any data speed indications, is it safe to assume the issue is with the device and not the network?

Thanks. I was trying just that (saw the *#*#4636#*#* code on another forum), and none of the options work. I'm wondering if that means my radio is dead. I don't want that to be the case, but I can't think of another explanation

You appear to not have an APN type set up.

Edit: use these settings. Except in the first APN remove the first proxy line.

I think I have the same problem as the OP. In my case, the HSPA radio connects about 50% of the time after a reboot. In my case, I'm convinced that the loss of signal is attributed to failure to communicate with the SIM card.
For the OP: Are your signal bars grey? or is it just an outline of a triangle on its side? If it's just an outline, the phone sees the SIM card, but cant retrieve the necessary data. To confirm, install a SIM info app from the Play store and see if the app see all details of the sim card.
I have already replaced the sim card, assuming I had a defective SIM, but the new card has not resolved the issue.
At this point, I think I need to RMA my phone.

It looks like the SIM details are being seen - I have voice and texting capabilities, and my signal bars are present but grey. Sorry to hear about your phone - my data connection is out 100% of the time though.
I've ordered a T-Mobile SIM to check this out - this way I should be able to figure out whether it's the network or the SIM.

Update: I've tried a T-Mo SIM and it works perfectly. So it's not the device.
However T-Mo isn't actually a viable option for me because they have very limited coverage where I live. Straight Talk keep telling me their provisioning is okay - any way to check on this? What other issues could I possible have that might be causing this?

Are you sure you have AT&T 3G coverage near you? I looked on AT&T's map for my work place and it shows 3G coverage but the entire county only gets 2G EDGE. And EDGE is horribly slow, I can't download anything. Went to Wal-Mart there and went to the wireless store and they confirmed that there is no 3G coverage in the area except for Verizon (which I had before this phone). I have an app called Network Signal Info, it will tell you what type of data network you are connecting too even when on wifi. It tells me EDGE2 at work HSPA at home.

Edit: just wanted to add that I read somewhere in a thread here that the colors blue and gray only signify if you are connected to google services or not. Blue you're connected, gray you're not.

Dead sure - as I said in my original post, I put my SIM back in my old (locked) dumbphone and it shows the 3G logo - though I can't use data on that phone because I'm locked out of the APN settings. And colleagues at work with have HSPA+ on AT&T. I can't try their SIMs though, because they don't use micro-SIM.
As for signal bar colours - even if there is no Google connectivity, it should at least show me a 3G or H/H+ next to the signal bars, which doesn't happen - and I cannot access anything on the internet anyway. I tried actually accessing the internet via the browser and various apps, I'm not deciding my connectivity based on the bar colours.

ALSO: When I use *#*#4636#*#* to turn the radio off and then on again, "GPRS service" goes to "connecting" but eventually stops at "disconnected". And the "network type" in that menu says "HSPA", so it looks like the network is kicking me off though I can't for the life of me say why that's happening.

I'm constantly get this issue where the signal bar becomes just an outline every minute or so and I lose connection. When this is happening sms becomes erratic (I receive texts multiple times sometimes 20-30 minutes after it was first sent, texts are received in the wrong order, cannot send texts until i restart phone).
Possibly hardware issue?

I had the same problem... could connect to the wireless network only if wireless data was disabled or WIFI was on.
Ordered a replacement which came today, and all is good Seems to be a hardware issue.

I to am having the same problem connecting to data networks. I have had the nexus 4 for about 2 weeks and its been an amazing phone until this morning when I had no data connection in town and around town. My iPhone 4 has 3G connection in the same area, with the same sim card. Ive already looked around the net and found the post to reset the radio but nothing happened. After not having radio or data for about 2 hours my phone finally fixed its self. I have no clue why I lost data connection or how it fixed its self. I will stay posted to see what happens but maybe there is some bad hardware in the device that is just now starting to surface.???

Hi I appear to have the same problem. My phone is able to make calls/text and etc with data off but when data is turned back on it screws around, doesnt connect to the internet, grey outline on service and etc. I'm thinking this is an hardware issue but how would I go and exchange this. One more thing, I bought this brand new from someone, does that matter?

If you want to RMA your phone, you can transfer the ownership by calling Google Play support. You will need the device IMEI and the email address of the original purchaser. Just tell them the phone was gifted to you. After the ownership is transferred, you can begin the RMA process.

Nexus 6P: Calling Issues — Cannot Make Calls, but Data/Texting Works (Verizon)

Hello,
I recently upgraded my Huawei Nexus 6P to 6.0.1 (dirty-flash, sideloaded).
I had trouble getting LTE to work at first (turning on/off Airplane Mode makes LTE work). I kept trying to change Field Test settings to make LTE work.
However, when I factory reset it the phone won't make or receive phone calls.
It sticks on "dialing..." and it just won't work. However, data and messaging work just fine.
I forgot to back up my EFS partition so it's partially my fault.
My IMEI number and MEID show correctly, however on the My Verizon website it shows a different MEID that's nothing close to the original one. The last 2 digits were different. Neither the MEID or IMEI were changed during the upgrade process, so it should have worked fine.
I recently called Verizon Tech Support about this and they said they'd change the MEID within 72 hours to 4 days. (I called Friday evening)
They kept having issues with the server rejecting the MEID and I checked, it's not blacklisted. They told me about a "wrong form" being filled out and ran some tests and nothing worked.
The phone MEID and Field Test menus showed properly though, just calling any other number (even Verizon's activation number) won't work.
I kept factory resetting, even downgraded to 6.0 (clean flash with recovery/radios, unrooting and all that), and LTE worked better, but STILL no phone calls!
Whenever I try to activate it on the website, it keeps telling me to contact their number. I'm not sure if I'll need a new SIM card because I've tried another SIM card and will also not make calls.
I'm not sure if calling has to do with the MEID or IMEI or anything else.
Do you have any tips/suggestions to fix this annoying issue?
Thank you,
Exec360

I've seen the issue going from Wireless to LTE and vice versa but I have no issue making or receiving calls. Texting and MMS work ok also. I went from 6.0 to 6.1 by doing a factory image flash. Now I'm Chroma and I'm curious if I would have this same issue on Stock so I will probably flash factory or a slim rom stock tonight. I'm on Verizon and had a nexus 6, I popped the sim in my 6p and it activated with no issue.

Same here, except I popped out the SIM from my iPhone 5S.
Ironically, when I put the same SIM back into the 5S, calling and voicemail, in addition to data worked, even though the device was recently deactivated from Verizon.
I'd say the issue probably comes up from a corrupted IMEI/MEID or other identifier. (Not completely sure about this though — the IMEI/MEID was the same between popping in the SIM for the first time and after resetting...)
Verizon detected my device as a Huawei 1511 phone and thinks it's an old Samsung feature phone when I run it through support/help pages.

I have the exact same problem with my phone and I don't know what to do.
update: I just flashed the efs backup file and it worked again.

I forgot to back up my EFS partition and I had 2 chances to do so...
My IMEI, MEID and SIM ID show perfectly in the About section, even when factory reset and bootloader locked, but calls still don't work, very odd.
I used Wugfresh and just about every IMEI recovery tool I could find (EFS Professional) but it keeps giving me errors such as "Access Denied..." with BusyBox installed.
Still no email or response from Verizon techs tonight, expecting one tomorrow.
If not, I'll have to RMA.

More specifically, I cannot find an EFS folder or a nv_data.bin file in any file explorer — Root Explorer, Solid Explorer, TWRP, etc.

Alright, I've actually figured out that the problem is NOT the EFS after I sent it in to Verizon.
My IMEI and MEID number and everything else were actually just fine.
It wasn't flashing or anything that ruined my phone... I recently called Verizon one night on my phone about LTE issues on 6.0.1 and after that, the calls just stopped.
In fact, the problem IS on their end.
They gave me a new SIM card and it didn't work. They realized the phone was new on the network and that would cause incompatibility issues.
Now I have to ship my phone to their IT department which takes about 2 weeks.
If that is your case:
Verizon guide to getting your calling back:
First, I'd try flashing an old EFS backup when your phone was working. If that doesn't work, call their support number (1-800-922-0204) and select the tech support option or say it if it asks.
Give them your SIM card number to try activating the phone. If that doesn't work, you can still send in your phone — just ask them and a phone kit will ship.
Sending it in to the IT department will take around 1-2 weeks, so you should definitely have a backup phone or communication device on hand (you can also just use Google Voice from a PC which is a great temporary solution).
I'll say, BIG props to Verizon for giving us very good support.

AN easier method is to use any Verizon phone with a microSIM and activate on their network.
Once the SIM is active, cut it down to a nanoSIM and put it into the Nexus 6P.
It just works. All this about sending your new phone to them for two weeks is crazy.
I pulled the SIM from my LG G3 and cut it. Up and running in minutes.

Unfortunately, my other phone does not have a microSIM. NanoSIMs usually work with LTE connections.
Trimming a microSIM is dangerous and could actually damage your SIM card tray and your phone.
Thank you for the advice, but I should warn you taking that risk may actually damage or cause issues with the SIM card itself such as not being able to read its SIM card number.

EDIT:
After 5 days, 3 factory resets, and many flashes of the older radio, it has been SOLVED!!!!!
First, try disabling, reinstalling the factory version of Google Connectivity Services, then updating it in the Google Play Store.
Next, dial *#*#4636#*#* on your phone application to get to field test mode. This function will work no matter whether the phone is working or not — it's just an information screen.
Click the 3 dots and select "change radio band". Select Radio Band 6, NOT USA or Radio Band 7 — Verizon told me to try both of those and they are glitchy.
Source: "Attaching 2 screenshots. One with band 6 where calling works but data is 1x. Another with USA band where LTE data works but no calling. Looking closely it's set to emergency calls only." (http://forum.xda-developers.com/showpost.php?p=64149076&postcount=8)
Now my GSM service is working and calls work extremely well!
Glad it had nothing to do with EFS/IMEI numbers after all.
Make sure to set your APN to "VZWINTERNET" if it hasn't been set already.
I'm glad I can share this with XDADevelopers so that they can benefit from this information.

In the US, all carriers are supported for Nexus 6P use. Since you live in Qatar, you may have a different carrier.
Here are a few other points or solutions for this issue:
If your carrier is not Verizon, does your carrier whitelist the Nexus 6P or only phones sold through them?
Do you get an IMEI number in the Settings application? (don't put it here for privacy reasons) If you don't, then your issue most likely has to do with accidentally deleting or modifying the EFS partition. Try restoring an EFS backup. ALWAYS back up your EFS before you install something else or root your phone — and keep it in a safe location! Alas, that was not the case for me.
Have you tried turning Roaming on inside your cellular network settings or have a specific roaming plan?
Do you get decent reception when making calls in Qatar? Where do you have this issue most, indoors or outdoors? You should get 1x at least.
Try the field test mode (*#*#4636#*#*) in the phone application. Go to "phone info".
If you see "GSM service: emergency calls only" on Verizon, the GSM band is not connected which makes phone calls. Switch to Band 6.
Otherwise, if you see the same thing for GPRS, try switching to another band. I'm not familiar with carriers except Verizon or other US carriers (AT&T, T-mobile, etc.)
I've emphasized this a lot, but try a factory reset. Lock the bootloader and remove your custom mods to the system. It may just work for you.
The case may be that the phone service does not work in Qatar, your reception is weak, or you have a specific phone plan. It may be your carrier not being compatible with certain bands, like GSM.
If that is the case, try calling their support and ask them for any possible solutions to the problem.
EDIT:
You also stated that you bought your 6P from Ebay. Many risks can come from buying used phones off of there rather than the official websites. It's likely that someone messed with the EFS and IMEI numbers.
It could be a stolen phone too... in those cases, it would be illegal (in some countries, not sure if in Qatar) to change the IMEI number unless you have an EFS backup. Sorry, you may just be out of luck. Try another solution like Google Voice or Skype (paid) for now until you get it fixed.

Thx bro

Here in qatar, i have one friend having the same fone from amazon and it is working fine. Here no CDMA plus texting and data are working. If the efs is corrupt or as u say screwed, it would work data and text? Band USA and 6 re ok with data and text.. Band 7 dead.

In general, it may corrupt the phone function but texts/data may work fine.
Most carrier connectivity issues usually come up from a corrupt EFS or the service not being activated on your plan.
http://forums.androidcentral.com/ask-question/423732-understanding-cwm-backups-efs-partition-etc.html
For you, it seems like Band 6 is the correct one. No CDMA — and GSM is working again. Good job
Another method to try:
Update the Preferred Roaming List (PRL) - dial *228 on the phone app or figure out your carrier's PRL update number
That might work, didn't affect my calls since I don't use roaming services.
By "Band 7 dead", do you mean that the service just won't connect? My issue came from messing with the bands to fix the LTE issue and messing up my phone.
Try to call your carrier's support — try getting a new SIM card or collect information about the Nexus 6P compatibility, if they don't have it on their website.
Was the phone working since you first used it? Have you rooted or done any system-level modifications to it? Also is your carrier Verizon, because I don't think they have strong roaming service in Qatar... I am in the USA right now using Band 6, working fine.
https://community.verizonwireless.com/thread/494218
When you dial, do you get "Dialing..." and just have to wait until it hangs up, or is there static, or a carrier message? Does your friend have the same carrier (Verizon) as you do?
Sorry I'm asking so many questions. I just can't quite identify your issue very well.

Thanks for exerting all kind of possible solutions . really appreciated ... I ll explain next everything ..
First of all I'm no verizon subscriber .. I just got the phone from ebay shipped to qatar .. that's all international buyer ..
well secondly, the service is activated. here is different than yours in activation process. Plus my sim card is working on all other devices, opo, op2, opx, mi redmi n2, moto g ...
I believe the problem remains in the piece I have now (nexus 6p) because im used to buy phones from the US and they work fine expect some missing LTE bands that does not really interfere with calling service.
If the EFS/IMEI is corrupt, will it register on the network normally? will data and text still work?
Band 7 dead means no text no data and surely no calls ... plus when I chose it, i always get called ended right after i press Dial a number
experience with other bands:
band USA: text and data working fine ... calls: when dialing, it keeps dialing until the network fails and returns again like reconnect (the bars disappear and return again) and when i hang up, it respond quickly and execute the action but on,
Band 6: text ok data ok , calls no .. but when dialing, it keeps dialing normally till it gives me (call ended ) and if I try to hang up after few seconds, it freezes the phone for like 10 seconds till it execute the action of hanging up ...
so the USA band is the most responsive band in terms of hanging up ..
when I dial *#4636 .... , and access phone information to change preferred network, it is usually set to LTE/CDMA/GSM (PRL) >> if i try to change it to LTE/GSM (PRL) because no CDMA here, it usually return to the default after restarting the phone .. it does not really change the network if, for example, I choose GSM only .. I still see LTE on the bar .. moreover, when i try to choose 2g from cellular networks from settings, it does not reflect and I still get LTE working .. weird ..
** in all cases, FYI, I always see the carrier name in the top left corner of the screen.
*228 does not work as Im not verizon .. plus any USSDs are not going through as it gives error "connection problem or invalid MMI code"
when I try to access caller ID, it gives error " network or SIM card error".
I tried to call the carrier but they could not do anything. I'm still expecting a call from their back office team who ( i assume ) has more experience
getting a new sim would not help because I have tried different active sims different numbers and I also tried the second carrier here in Qatar (vodafone) and the problem persist.
the fone never worked since i reached Qatar. It was not rooted. I only unlocked BL and flashed the first factory stock rom (fully including the radio), yet nothing
wait wait please don't lose hope
one friend here is also giving me ideas and solutions to get over my isssue, he suggested i flash chroma rom bcz it has more bands. I will flash it and give a feedback.
I really appreciate your efforts and also his efforts @Soulfly3
pardon me if I wrote too many things and for giving all my trials not in order
Thanks

Thanks everyone for helping me resolve my issue. biggest thanks goes to @@scoobysnack who helped me greatly to get over it.
Installing Chroma ROM solved the issue because basically it was a problem of bands. Chroma had more bands that work in Qatar. and I could return back to stock rom again without any problems ( but don't mess up with bands in phone information )
Thanks @Exec360 for offering me your great support >>>

I told you chroma would solve your problems. it has different bands to select and I figured the "AUS" bands would work.

Any advice for those of us operating on Verizon's extended network? I'm using my device on the Appalachian wireless network (with whom Verizon has a network sharing agreement as part of it's LTE in Rural America program), and I'm constantly getting the roaming indicator, even though I know I'm not roaming. I've never dealt with this on any other device, and I've used 4 different devices encompassing both Windows Phone and Android. If I switch the CDMA roaming indicator to "Home", the roaming indicator disappears and the usual LTE indicator appears, but I'm unable to make voice calls. If I switch the roaming indicator to "Automatic", I can make voice calls but the roaming indicator returns and the device tells me I'm roaming inside the test menu, even though Verizon tells me I'm not incurring roaming charges. If that's true, then the roaming indicator is just an annoyance, but it's there constantly (even when on WiFi) and for me it's a significant annoyance. Is there anything I can do, or is this just something I'm going to have to live with?

A hard one – Wi-Fi calling option missing from settings after Sprint activation

Guys this is a very difficult one. I really appreciate your help. If there's any place I can get an answer I think it's here.
My Nexus 6P had the Wi-Fi: option in the settings, I saw it many times. However after activating the phone with Sprint (during the process the agent Keith something into my phone which caused it to download and install something from their system) the Wi-Fi calling option is gone from the settings. I've tried everything I can think of to get it back and have been unable to.
I have a very new Nexus 6P running 6.0.1. I purchased this phone especially for its Wi-Fi calling capabilities to use on the T-Mobile network. At the time of purchase there was a lot of conflicting information about Wi-Fi calling coming from T-Mobile's customer support/technical support and numerous support people were saying the 6P is the only phone they were sure would work. I used the phone on T-Mobile's network with Wi-Fi calling and the Wi-Fi calling worked flawlessly, but there were other problems with their service so I moved on to Sprint. Sprint's Wi-Fi calling was horrible, in fact I don't think it was really doing Wi-Fi calling, I think it was just calling to the cellular network. During my time with Sprint I noticed that the phones Wi-Fi calling settings were gone. I contacted Google and they said that if Wi-Fi calling is not allowed by the carrier then the option would not appear in settings. I don't know if that's true but that's what they said. I assumed moving onto Verizon which does offer Wi-Fi calling would restore that option if it was just a matter of having a Sim card which commanded the phone to enable Wi-Fi calling. However after switching to Verizon I still have no Wi-Fi calling settings, and I am unable to make Wi-Fi calls.
In an attempt to get my Wi-Fi calling features back on the phone by factory wiped the number of times from recovery, I also upgraded to android N beta, I also routed the phone and tried installing Cyanogenmod, I also installed pure nexus, I also returned back to the stock Marshmallow, and nothing restored the Wi-Fi calling option on the phone.
I believe what the Sprint agent dialed on my phone to cause it to download and install something from their network is ##72786#, though the agent also dialed ##873283# and ##675#.
One of the Verizon technical support agents suggested that I dial *#*#72786#*#* but when I do that nothing happens except what I dialed clears out of the dialer. I used one of the apps to discover secret codes on my phone and it shows that code is handled by an application called SprintDL. I know some people whose Nexus 6P have never been on the Sprint network also have that application, so I'm not sure if that is something that was installed during the activation process with Sprint.
Now I'm wondering if I need to reflash the vendor information or the radio modem information part of the ROM. It seems like all the roof flashing that I've done would have flashed over everything that could be flashed. But it does seem like something happened to my phone, something was installed or changed or replaced and whatever that is is surviving through multiple factory wipes and ROM flashings.
Sorry for going on, but I want to pass along everything up front so I don't receive irrelevant responses were requests for more information.
I will be so grateful of anybody can help me out of this mess. I live in a place with very poor cellular coverage and Wi-Fi calling is critically important. If I have to send this phone back to Huawei all have to purchase another phone to use in the interim.
Thank you in advance.

Surely you jest. But of course.
Honestly, do you think someone who's rooted their phone and has flashed a number of different ROMs wouldn't know or how to look in the settings?

Thank you so much! So you mean that:
A) your phone has the Wi-Fi calling option in the settings but it does not work with Verizon?
– or –
B) because you are on the Verizon network the option for Wi-Fi calling does not show up in your settings?

I do not have the wifi calling option in my settings. I've always been with Verizon so I haven't tested it with another network to if that would change. I wish I checked to see if it was there before it was activated but I didn't. I'm fairly sure the option just doesn't show up if the network doesn't support it.

Thank you so much! That is so great to know! I know that my setting for WiFi calling was there because I received the phone and played with it before I activated it and the setting was there. It was there when I was with AT&T and with T-Mobile.

I just found out what the problem/solution. It's the sim card. Today I purchased a T-Mobile sim card and even before it was activated, as soon as I popped it in my phone presented a notification about wifi calling and sure enough I checked the settings and the wifi calling option was back.
So if you have a 6p and the wifi calling option is not visible it's because of your sim card. Removing the wifi calling disabled sim card, rebooting the phone, reflashing the rom/firmware does NOT restore the visibility of the wifi calling option. The only thing that will restore the visibility of the wifi calling option is to insert a sim card that is wifi enabled.
I wish the good folks at Google or Huawei knew that the wifi calling setting's appearance or disappearance is tied to the sim card. It would have saved me a lot of work and headache

So having installed the sim from T-Mobile got you back the Wi-Fi settings back but when you put back the Sprint/Verizon sim did it remove it again or not? And if it didn't did Wi-Fi calling work on Sprint/Verizon? Or do we have to call and order a Wi-Fi enabled sim from our carrier?

Verizon compatibility broken after update?

Hey guys, I just saw a YouTube video that was posted yesterday where the guy shows that after the update he no longer could connect with his Verizon SIM card in the axon 7. Has anybody else run into this? Mine won't be here until Monday but if this is true I'm going to be sorely disappointed. Thanks for your input.

I am on verizon with no additional problems after the update. I am still always roaming, and my signal is the same (more bars but still the same reception). LTE, MMS, SMS, Cdma all work the same.

I'm really glad to hear that. I'm not so sure the guy knew what he was doing either... Lol :silly:

Quick question for you bud. I currently have the Moto Z-Force, but I want an unlocked phone that I can root and mess around with and unfortunately this phone doesn't have that capability. Would you say this is a great alternative in terms of functionality and specs? Tia

My VZW situation. Just an FYI post AND how to fix it.
I'm on Verizon, have had my Axon 7 for over a month now. No issues other than not having VoLTE, and the occasional software farts (Using Nova Launcher now). When I initially set-up my phone, I imported all previous apps directly from the Play Store. I should have known not to install the VZW apps that were previously installed on my HTC One M8 (purchased directly from VZW), but in my excitement for the new phone, it skipped my mind. Anyhow, no issues through 9/19. "Verizon" displayed as my carrier, and full access to the LTE network.
Fast forward to 9/20 (post B27 update) when one of the VZW updated automatically (I don't recall which of the 2 apps I had installed), and BAMM, "123456" displayed as my carrier and no more access to the LTE network (3G only). Later that evening, my VZW account showed my number with an "unauthorized, non-VZW device", whereas, before the VZW app update it showed my HTC one M8. I removed the SIM and shut down the phone, re-installed the SIM and re-booted....nada. Tried what seemed to be every permutation of replacing the SIM card, played around with APN settings...no dice.
My feeling is they booted me off 4G LTE once the app recognized I was using an unauthorized, non-VZW device. The steps below solved the issue (Provided by "vzwcdma" via the ZTE Community Forum).
"As for losing LTE connectivity, I've had a similar problem before, both on the A7 and other devices. On other devices, like Motorola devices, I could just boot into the bootloader and clear the modem state partitions via fastboot, but ZTE seems to have disabled that function in the A7's bootloader. So, for the A7, I had to mess around a bit with the modem mode. Download "Network" or "4G LTE Switch" from the Play Store. Open it and scroll down to "Set preferred network type", where it should say "LTE/GSM/CDMA auto (PRL)". There isn't really a set guide for what you have to do, but try switching into LTE-only mode, try hitting "Turn off radio" and "Turn on radio" (not Airplane Mode), maybe try "LTE/CDMA audo (PRL)", maybe turn off radio, switch to LTE-only mode, turn on radio, etc. At some point (I'm not sure what) the phone will reset its modem state, and should re-connect to Verizon LTE (and when it does, switch the network type back to LTE/GSM/CDMA auto PRL.
My Verizon account also shows "unauthorized, non-VZW device". Shouldn't affect anything. I've been using an unauthorized/non-VZW device prior to the A7 with no issues as well."

Good to know! I've had so many phones and this hardware looks so awesome for the price, but of course vzw isn't gonna play nice with it without some work. Looking forward to getting mine

Verizon still working fine for me.

After the b27 update I saw improved signal strength. I'm on page plus mvno. After driving in a fringe reception area, I lost lte,and I showed as roaming. It seemed to be using boost Mobile from what the phones network menus displayed. Axon doesn't have a mobile network setting for 'system b', only auto & home only. Tried both, rebooting each time, no fix. I ended up resetting phone, fixed it all. I then switched mobile network to home only, and hoping that it's done.
PS-after b27 I had to re-enable a couple settings, pinch for screen shot, etc.
Edit: it's now been several weeks with it set to home network only. I daily drive in fringe reception areas and have better signal strength than ever, with any phone/carrier combo. All is great, no more issues. Great phone!
For reference, I'm on page plus mvno, dropped in my activated sim from my old phone into the right-side sim slot for CDMA services. Then set to home only. Done.

Just wanted to see if anyone else had inputs of post update Verizon service, good and bad... hasn't been a ton of chatter in the last week. I have a phone on its way from the egg, trying to decide if it's worth starting a new sim card with Verizon and dealing with that work around... is getting the number off a display and ordering online still the easiest way to get activated?

Works great on VZW still. Love the phone.

I'd say that the Axon works just as well on Verizon as it did prior to the update, but with potentially better signal strength though I didn't really have a big issue with that prior to the update so I'm not sure (the T-Mobile SIM does seem to do a lot better post-update...but Verizon has always worked well).
I really doubt you'll have any substantive trouble with VZW on this device, especially if you're willing and able to mess a bit with some of the more advanced settings just in case a problem does arise. Here are the oddities, and I'm trying to list *all* of them!
1. No VoLTE or (I presume) HD calling
2. Voicemail appears to have to be accessed by dialing *86 as opposed to long-pressing the '1' key
3. Roaming icon is present intermittently
4. Data roaming *must* be enabled to ensure consistent and reliable data service
5. Verizon's website won't recognize the device at all in the Account Overview pages (mine still shows the last "approved" device I had with my VZW SIM - an iPhone 6S)
6. MMS *may* require a hack to get the proper APN, though I've had no trouble with this (I'm prepaid though); the hack requires a GSM SIM, so beware of this
7. 1X reception *seems* a tad weak in terms of dBm but functionally it almost seems better than my other Verizon phones (weird!)
8. Carrier label will be either '123456,' '002127' (EvDO only), or (I think?) '31000' when not using LTE (i.e., 1X or 3G). When on LTE the phone should show "Verizon Wireless" as normal
9. A SIM/modem reset may be necessary once in a great while it seems...so it's good to understand how to navigate to the "Phone Information" screen to toggle radio settings...also, I've found just SIM-cycling with a GSM SIM will often fix any connectivity problems as well...and sometimes just rebooting the phone with no SIM at all can help too (or a combo of all the above!)
If you can tolerate the above issues then the phone is great. I really enjoy it. I've found the Verizon side of things to be pretty reliable on the Axon 7, even with my endless tinkering with radio modes and other stuff, which has seemed to get me into (recoverable) trouble a few times.
Most importantly - the endless chatter on various forums that Verizon "blocks" the Axon 7 and other non-approved devices is total bunk. In every case where I've run into an issue it can be resolved on my side - Verizon is doing nothing whatsoever to inhibit the use of the Axon 7 on its network as far as I can tell (notwithstanding activation hurdles, admittedly)...many of the people making such claims seem to be speaking from a standpoint of total ignorance and it's kind of getting annoying, to be honest...it seems like the minute someone has an issue with the Axon 7, some ignoramus gets on the relevant forums/comments and claims that Verizon is "blocking" the device. Total BS IMO.
Good luck! As far as activation is concerned...I'd say it might be best to just go to Wal-Mart and buy a cheap prepaid phone or something (looks like the HTC Desire 526 has a nano-SIM and is only $37.49 on their website)...or maybe a cheap nano-SIM'd Verizon phone off of Swappa or eBay? That's probably what I'd do...But I know neither of those solutions are particularly helpful...VZW definitely makes it a bit of a pain.

#6 might not need the GSM SIM workaround anymore after the B27 update. The + sign shows up for me all the time now, even if I only have a Verizon SIM inserted.

thanks for the list guys, i think i'll give it a shot. i'm going to try to add it as a second line to my wifes plan online. is borrowing a friends imei from a nano phone still the best way to get a new activated sim for this phone?
that 526 is a predaid, will verizon just switch that sim to plan if i call in? or are they different?

found this, not sure if this is still the rule...
http://www.prepaidphonenews.com/2016/02/new-policy-may-require-verizon-prepaid.html
"It turns out that Verizon made a policy change effective 1/17/16 that requires Verizon Prepaid Phones to be activated on Verizon Prepaid and have at least $30 in airtime applied to them before they cam be used on Verizon postpaid. A Reddit user posted a copy of an internal Verizon document detailing the new rule:
Effective 1/17/2016, customers who purchase a Prepaid 4G device must activate on a $30, $45, or $60 Prepaid plan and make at least 1 monthly service payment before they are eligible to move the device to a new or active Postpay account .
Device remains locked until first month’s payment is made on their Prepaid plan.
Device is unlocked automatically upon successful first month’s payment and can be used on Postpaid plan (new SIM or SIM swap).
Attempting to use an active Postpay SIM Card with a new 4G LTE Prepaid PIB smartphone prior to making the required monthly payment, hotlines the Postpay MDN (SFO 83643) . The hotline remains until first month’s payment is made.
Customers who activate on the $45 or $60 Prepaid plans and enroll in Auto Pay, receive bonus 1GB data per month.
If account is hotlined:
Data access, outgoing calls, and text messaging do not work.
Text message is sent to smartphone.
*VZW FREE MSG: Phone must be activated on Verizon Wireless Prepaid service and first monthly payment must be made before it can be used with any other service. *
Auto-remark is placed on the customer's account.
*SIM Swap attempted: MDN Hotlined. Phone must be activated on VZW Prepaid service and first month paid before it can be activated as postpaid. *"

Dang...yeah I think you're right about this. My mistake...ugh I wish they'd just make it easy! In that case I'd say Swappa would be the best route...I've bought a few phones off of there and it's always been a great experience.

What are your APN settings? I'm having issues getting my data to work on Verizon.

So frustrating. Before update used today Verizon in upper left corner. Switched to 123456 after update. Rebooted and it went back. After another reboot it only says 123456 and nothing I do will change it back. And now when I get an MMS hangouts tells me it needs to download it but nothing happens. I never get LTE anymore either.
Edit: not sure what I did but it's back now. Might have something to do with bearer in apn settings being lte.

That's #9 in the above list that was posted. Need to cycle the modem state of the device.

so, can someone help me with a little clarification? did ZTE ever actually disable anything regarding Verizon on this phone? i know when people quote the webinar, it sounded like they were going to. i understand that the functionality is basically all still working, but i'm wondering if maybe i'm confused on the terminology.
in this post on reddit, i heard the same thing that has been repeated by some, and i am wondering if i have my band terminology confused. is the cdma part different from the 4g lte part(and that's why it's still working)?, or is sarah just incorrect?
SarahSchmera 3 points 9 hours ago
Axon 7
Doesn't work on Verizon yet. It supposedly has CDMA radios but the radio firmware has them disabled. ZTE can't by law enable the CDMA radios because they didn't get FCC approval for the CDMA radios. They would have to pay for the testing and then resubmit the device to the FCC to get approval before they turned on the CDMA radios through a software update.
And the device doesn't have the firmware for VoLTE, HD calling or WiFi calling on Verizon.

Lost LTE on Verizon

Ok... I screwed up! There is a new Verizon tower near my house and I wanted to update my roaming, so I did the *228. Alas, by accident I chose option 1 (Program phone) instead of option 2 (Update roaming). Immediately after that I lost LTE. 3G is the best I now get.
I am running 7.1 latest update. Not rooted.
Suggestions on how to get LTE back up?
Thanks!

That describes steps if I were using Oreo but alas, I am on Nougat. I will look for similar issues.
Thanks!

Tried the recommended steps. Worked for about an hour. Then back to 3G. THEN noticed I could not send a text message! GROAN...

Try this:
*#*#4636#*#*
Phone Information
Change Preferred network type to LTE/WCDMA
If after cycling your connectivity it doesn't pop onto the Verizon 4G network, reboot your phone, you should be good then.
I dont know what it is about that setting that is different, because Verizon doesnt support WCDMA, however this seems to select the correct type of LTE connectivity and you'll be in that. Be aware though, this will likely prevent 3G from working if you enter an area without good 4G coverage.

I have tried all recommendations. LTE works for a while then it is back to 3G. On a further note, when this happens I cannot send a text message but a reboot will solve the text message issue.
I am at a loss. It seems there is no way to make the settings accessed by *#*#4636#*#* STICK.

It not just you. I have been frustrated for weeks. I thought it was only because I upgraded to 8.1 but your situation just answered that. I just ordered a new SIM from Verizon and wont run any programming once I install it. I contacted Essential on it as well as others. I hope the two can work this out.

Best option is a new some. *228 is usually no suggested on LTE unless you really know what you are doing. The PRL should be automatic on LTE.

get a new sim, your is borked now most likely

Will try new SIM tomorrow and let you know...

A VZW rep had me do *228 when I was having some issues with texting when I first got the phone. Fixed the texting issues but then I couldn't get LTE either. A new SIM fixed both issues I was having. *228 is apparently known to bork VZW LTE.

Had the same issues after using the *228 method I advise not using that at all been stuck on 3g since. Getting a new sim thursday hoping that helps (using straight talk Verizon Sim)

Here is a bit of information I have discovered. The phone is stable as long as I NEVER turn on WiFi! IF I have WiFi turned on (no connection to a network required) AND I enter a poor or non-existent service area, I loose service until I go back in with the *#*#4636#*#* and change settings back yet again!

anyone with a new sim got it working? Verizon shipped me one today and put it in. Avoided calling 228 but cannot get the sim to activate itself.
Got a SIM not provisioned error. I turned it off, took the SIM out and checked it, put it back, rebooted and still nothing. Not connecting to Verizon Network. Im afraid to call support because they will insist to call 228 to program it.

BTW the final version of 8.1 fixed all the Verizon weirdness I had going on. I popped it back in 'Global' in the Mobile Network settings (which is equivalent to 'LTE/CDMA/UMTS (PRL)' in the Phone Information section) and it hopped immediately on to Verizon, no kinda looking like sprint, no blank, no need to dial *228 for a new PRL it just worked. In fact on reboot it doesn't sit there with No Service scrolling across the screen for 15-20 seconds after boot, it shows up Verizon Wireless immediately.

That's good to hear I switched to an old straight talk TMobile sim I had while I wait for the replacement straight talk Verizon version hoping things go as smoothly for me when I pop it in

Very frustrating for me. This is my only concern with this phone . Im still stuck in 3G after doing the upgrade, hard reset, and popping in a new SIM without dailing 228. I will change my Mobile Netwok settings to yours above.

May you should try reinserting your sim my phone self corrected once my update was done.

Here are my results:
Installed new SIM - same issue
Did a network data settings reset
Verizon did a flush and reinitialize of my account.
Still same result.
Don't know exactly how or why but about 10 mins later I noticed my phone was OFF.
I powered back up and MOST issues we're gone.
The final fix was to go into developer options and turn on "cellular data always active"
Working great on LTE+

Try putting it in "4G/LTE", wait for it to connect, then back to Global.
After I posted my above message, I did go mucking around in the settings and got it stuck in 3G (even after reboots, etc), then corrected it by doing this.
And quick clarification for the post above this one, it is "Mobile Data Always Active", mine was already on and I never modified it, so that must be the default.
