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

I second this. No issues on Verizon unlimited plan after update. Always showing roaming also. Mms, sms, calls work as suppose to. All out of the box settings.

I can third it lol no issues here. Mine actually has better signal after update on verizon and sms/mms everything works still no issues anywhere

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?

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.

OnePlus 3T T-Mobile VoLTE issues/fix

I know this has other threads, but I wanted to post something that helped me get VoLTE working that none of the other threads addressed.
Quick background: new to TMobile, new to the 1+ brand. Rooted, stock. I could get LTE, but I kept getting kicked to roaming AT&T H+ or 3G, couldn't get VoLTE, and very slows speeds even when on LTE. Tried every APN combo, network settings reset, factory phone reset, tried every *#*#4636#*#* preferred network type...nothing. Chatted in to 1+ asking if I could speak to technical support. The response was the only way to fix it was to factory reset (which I had already done) and downgrade OOS. The newest OOS has the T-Mobile optimizations, so downgrading makes no sense! Needless to say, the whole 30 min chat was a waste of time and just a bunch of weak canned responses with no attempt to really help or figure out how to escalate me to someone with some knowledge of the APNs and settings needed.
Out of desperation, or since I had tried every other possible trick, I went under my T-Mobile SIM, Network Operators, and toggled Auto Choose and manually chose TMobile 4G.
Boom, full bands 4, 12 and VoLTE, and normal speeds! Carrier aggregation is even working sometimes.
I don't know why Auto Choose doesn't know how to grab 4G permanently, but everything is working!
Does anyone have any idea why this fixed it? Since I choose 4G, will I lose my ability to get 3G in rural areas? I don't feel like there was much info on how VoLTE is provisioned on the phone.
What's everyone's experience with the preferred network settings? I'm currently in LTE/UMTS, and I don't have the LTE/GSM option that apparently everyone else has...?
Also, does everyone else have as sporadic speeds as I do? One moment it'll be 40 down, next it'll be 6? I know it has to do with bands, but should there be a way to even that out a little?
Sidenote: I really like 1+ mentality about rooting and software, since I have to have a rooted phone, but this experience really soured my first impression. Plus their 1+5 is a major letdown to me. I don't think I'll purchase anymore 1+ products.
Feel free to correct any misinformation in my post.

I also have noticed when I try streaming, webpages or speedtests the little LTE+ carrier aggregation kicks in to combine band 4 and 12 and I get pretty good speeds. See screenshot

My speeds do definitely vary on Tmobiles network. Isn't an issue for me, everything streams fine, also i haven't had an issue with VOLTE since I got the phone in February..

I noticed when I'm in a roaming area, instead of roaming now, I completely lose service. I believe this is because I manually selected TMobile 4G as my operator instead of auto, which would allow the phone to jump to AT&T. Any ideas?

So still having problems, but only when traveling. If I have network operator on "auto" it'll select AT&T roaming, but then it'll just stick then and never switch back to TMobile, even in full strength band 4 or 12 areas. I have to reboot, and toggle auto for it to grab a T-Mobile signal. Very irritating. This also kicks the phone off VoLTE, and I've yet to get it back. Not sure if this is TMobile or the phone's fault. Tried everything I can think of. Any ideas?

Excuse my ignorance, but what would a new SIM accomplish, technically speaking that is?

I've had same problem as yours, I went to T-Mobile store and told them what was going on. They switched my SIM card and problem fixed. I was told because my SIM was too old (4 years at least) that's why i was having such issue.

New SIM, no change
This phone has the features I want, and T-Mobile has the speeds I want, but this is frustrating to be kicked to roaming and no VoLTE....

Sorry to hear that it didn't work out for you. I attached couple of screenshots just to show you that it's been working good for me after I switched SIM card.
Edit: have you tried to create a new APN instead of using the default APN?
Edit 2: I can show you my APN if you want

Sorry, must have not been clear. I can get LTE, just not automatically after going into a roaming area. It just sticks on AT&T roaming until I manually go back in and select TMobile 4G. The problem with that is when I do need roaming to work, it won't because I have TMobile 4G manually selected.
Another problem is that I can't get VoLTE to stay very long, in fact i haven't had it for a couple days, despite me being in a very strong LTE area.
I appreciate your help
Edit: yes, if I could see your APN that'd be great!

Just create a new APN exactly as mine and see if it works

Hmm yeah that's the one I have too....
Btw, maybe I just needed to wait,, but VoLTE is working again, and it's reporting the correct IMEI (it wasn't before but TMobile told me that wasn't a big deal...I beg to differ because now my TMobile app is working whereas before it wasn't) Fingers crossed the new SIM did the trick! I'll know tomorrow when I commute to work and it starts roaming whether it'll reacquire T-Mobile and VoLTE

Quick update: I definitely have noticed an improvement in jumping off AT&T roaming back onto TMobile LTE. AND VoLTE is now sticking. But... I'm inclined to think it's something related to me not having my second Verizon SIM in. I have a company work number on a Verizon SIM that enables me to text and call from that number. Obviously data doesn't work but that doesn't bother me since I have TMobile unlimited on my personal SIM. When I insert my Verizon SIM in the second slot, my IMEI number changes in the testing menu, but not my settings info! What the heck? The IMEI number identifies the phone and shouldn't change...I thought? Very confused why part of my phone retains the correct IMEI and the testing changes. I instantly lose VoLTE and my TMobile app fails to authenticate.
What is going on???
UPDATE:
I popped my Verizon SIM in again (slot 1) and it's reporting the xx...15 IMEI (correct one on my T-Mobile account) and the T-Mobile SIM (slot 2) then drops to xx...07! I'm so confused! I thought the IMEI is NOT supposed to change because it identifies the device?? The ICCID is the SIM number? Why is Verizon SIM screwing this up?

S7 SM-G930V can't connect to Verizon Mobile Data

Hi everyone, so I recently purchased an S7 SM-G930V and I'm having some problems with the mobile data connection and was hoping that someone on here might be able to help me out. I've been heavily researching and trying everything I can find online for 2 weeks now trying to figure out why I cannot get this phone to connect to mobile data and I'm about to give up and use it for target practice.
So here's the story:
I bought the phone from a seller on Ebay (I know I know) and it showed up in flawless condition externally and SEEMED to work perfectly. Upon receipt of the phone, I noticed that my current simcard wouldn't fit so I took the phone to verizon to get the nano sim and have it activated. The guy put the sim in and booted it up but after about 15 min the phone was still saying that it was "activating" so (being in a hurry) I told him that I'd just let it activate and be on my way. About an hour later my phone chimed saying that activation was complete but I noticed that it was showing H+R for a data connection which I believe meant I was roaming? Anyway I didn't think much of it because I was in a pretty rural spot in Alaska and the service was spotty.
Now here is where the problems started. Once I got home I noticed that the phone was not picking up any 4G LTE data at all and was bouncing back and forth between 3g and 1x but wasn't actually connecting to them, just finding them (greyed out). I rebooted the phone to see if maybe it just needed to update the local towers or something but it still would not connect to any mobile data at all so I took it back to the verizon store and they swapped the sim for a new one. Now, the phone will not activate AT ALL. The guy tried 3 different sim cards and nothing. It shows fully connected (5 signal bars) for voice but just cycles randomly between 3g and 1x data and will not connect to them let alone even find 4g lte service. When it connects to the towers it shows Verizon Wireless as the connected carrier but since it can't connect to data, it won't activate. The guy finally told me to call tech support and after about 3 hours on the phone with them, they pretty much told me they don't know what's wrong and to get a new phone.
So I decided to hit the internet and try out every option I could find before just sending the phone back. However, after countless hours of tinkering with the phone including rooting the phone, updating the firmware, factory resetting multiple times, clearing cache, disabling the cell radio and changing settings in build.prop, default.prop, apns_config.xml etc etc and getting nowhere I am stuck. I was really hoping that this was just a software issue or APN/modem/radio band etc issue that I could fix but it's looking like it might be a hardware problem or it's way above my skill set.
TL;DR
Verizon Galaxy S7 will not connect to any Verizon Mobile Data Network and therefor will not activate but it will connect to data while roaming? Any and all suggestions, help or advice is appreciated! Even if it's just to tell me that the hardware is faulty and I need to replace the phone. I just need some opinions from the pros if possible. Thanks guys/gals.

Moto g5 Plus Verizon issues

Hello. Moto g5 plus unlocked 32 gb from amazon, no prime ads. Unlocked bootloader, custom Validus 8.1 rom and TWRP recovery. Was previously with Redpocket Mobile, switched to Verizon prepaid ($40/month plan) and received my 4g LTE sim card yesterday and have been having nothing but problems since then.
TO start, the sim took a long time to register my number, and "program" itself as Verizon called it, this is because I finally figured out even though Verizon claims excellent coverage in my area (49783 U.S) I currently have barely any service, so that's why it took forever to register/port my number over.
SO now I can hardly even send a text with the stupid thing, it's resting on 1 bar and then usually disconnects frequently and says "no service." When I go into town I get 3/4 bars of 3g , not 4g LTE. I was curious as to why this happens, so I spoke to a friend who has Verizon in my area and he said it's a deadzone for verizon where I live, but that he gets 4g LTE everywhere else in the city.
Does anyone here have a Moto g5 plus US version (no indian/foreign versions) PURCHASED in the US and on the Verizon network? Also, my friend is on postpaid network, not prepaid, not sure if that makes a difference. IF anyone's with Verizon here can someone confirm it's compatible? It shows up on my Verizon account as XT1687. I got this plan for the extra data and rollover/hotspot capabilities that redpocket DIDN'T have, but if I can barely even send a text message at home what's the point? I have been on the phone with Verizon for hours and they claim my phone is compatible but that they "cannot guarantee coverage on phones not purchased from them" or something like that. Does having a custom ROM affect coverage in any way?
Couple more symptoms to help you guys diagnose my issue: In settings > about this phone > sim status, when I click mobile network status it usually "refreshes" so if it had listed one bar previously, I tap on it and it will say "no service" which to me indicates tapping on it updates it, and that the phone is constantly losing signal. Also, I keep getting messages about leaving service and roaming, though roaming is turned off.
What I'm most intrigued about is I can make calls from anywhere in the house unless the phone says "no signal" so even if the phone is on one bar and listing x1 for service or 3g, a call will come in or go through fine, but MESSAGES WILL NOT SEND. In android messages, it says "tap to send again." Which is weird because if a call could go through certainly a simple sms would?! I still have yet to test service in the heart of the little city I live in, I've only been outside of my house and in, so I haven't extensively tested different areas yet, so I'm not giving up yet!
Finally, what APN should I use? It's set to "straight talk verizon" right now, but there's a bunch listed. Perhaps other Moto g5 plus users could confirm which one they use? I suppose it sets itself by default...
thanks for looking through and please answer my questions! I need more competent help than Verizon can offer.

G935U No Service

Okay so I have been fighting this phone for months now. I am so ready to just sell it to some phone trade-in company for $175. I am at a complete loss.
My father-in-law ran over his SM-G935V (yes, Verizon) with a golf cart and broke the screen and back plate. He then gave me the phone so I could fix it and use it. I replaced the screen and back cover on it and ordered a verizon sim card (I was on straight talk BYOP program using an ATT sim card) I activated the sim card and it didn't work on this phone. It just said, "Searching for Service". I put the sim card in my Moto X (Pure Edition) and it worked fine and had full signal. I took it back apart and made absolute sure that the antenna and every other connectors that I unplugged were seated and connected properly.
Seeing all the verizon bloatware and that it was on 6.0, I then thought it may be a software issue so I decided to get the G935U 7.0 factory unlocked image from sammobile.com. I waited for like 4 hours and downloaded both the unlocked version and the Verizon version. After using odin to flash both of them (one at a time of course) neither worked . The flash did work perfectly in every other aspect and the phone is now a G935U. I still have the original problem, however, where the phone shows "no service" and wont connect to a cellular network. It auto configures for what ever sim card type I put in (verizon, ATT ect) and connects to Wifi.
I'm so done with this thing.
Any suggestions?
Thanks guys!!

I have the same problem, I haven't find any fix to this error...

I didn't have much money into the phone so I sold it on one of the phone trader websires for $180.
Case closed haha

No service message
I'm using smg935v with straighttalk byop sim card.. every time I restart my phone it says searching for service.. no text messages or incoming phone calls can be recieved. However, if I open the phones dialer and attempt to complete any dialed number.. Verizon wireless reappears and full phone functionality returns. I realize this is way late on your post and this probably doesn't matter.. but this may help anyone else experiencing this issue in the future.

I have a Verizon Galaxy S7 Edge G935V. I use it on Straight Talk with the AT&T sim card I took out of my Nexus 5.
I had to go into the settings and change it from CDMA to GSM. There is another choice called Global.
I tried both GSM and Global with same results.
Next I went into the APN settings and added a new APN. I entered all the information required for Straight Talk.
The phone is working fine except for 2 things I noticed. The verizon s7 Edge is missing LTE Band 17 and I think 12 too.
In my area Band 17 LTE is what my nexus 5 would connect to verified by an app called LTE Discovery available on Play Store.
On the S7 Edge it doesn't get Band 17 LTE. Fortunately I can connect to another band but its not quite as strong but it works.
I can surf, text and send pictures. When sending pictures I noticed the messenger program (default) isn't reducing the size of
the pictures small enough to work with text messages. I struggled with this for a week until I tried an experiment.
I used an app called Photo and Picture Resize. The App lets me take a picture, resize it and then send it with the messenger app.
Once the picture was reduced it sent fine. My nexus 5 never had this problem.
The other thing I noticed is sending a video text results in terrible quality. I have tried the lowest resolution
to the highest resolution setting with no improvement. I did a search on this and others seem to have the same
problem with the other versions of the S7 Edge, S8 and S9. I would like to find a fix for that.
The straight talk site offers the correct APN settings should you not know what the are.
