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?
Hi everyone,
I've been a lurker of this site for a little while now, so thank you all for your productivity and guides (If I can get this to work, I will create a guide myself to share ) I recently purchased a Brand New Sprint Galaxy S5 (SM-G900P) with the hopes of unlocking it and using it on Straight Talk AT&T's network. I've made incredible progress so far, but I feel like I'm missing something. Up to this point I've spent countless hours online reading about this device and troubleshooting it.
Current Issue: Phone will not contact any GSM network. I have the sim card in and it just says no service. I know this is only on GSM networks because I disabled all CDMA bands using DFS. All AT&T bands are active and I believe the Galaxy S5 supports almost every band available. APN Settings are set correctly.
Things I have done / tried:
Using Cyanogenmod13 KLTE ROM, Cyanogenmod12.1 SPR ROM, Unofficial CM13 SPR ROM. Also, tried using a "stock?" 4.4.4 ROM that was a little glitchy, but worked nonetheless (tried using SSU.apk here, but afterwards it seemed to sim-lock my phone by giving "Invalid SIM"
Phone unlocked with IDoneApps (no more invalid sim) IDoneApps says its for International and Domestic.
I paid for a Network Access Code and registered the phone with Straight Talk and attempted to transfer the service over (not sure if this is necessary as I am using a GSM SIM, which still works fine in my other phone, perfect service)
Also, on the stock ROM it keeps trying to "Activate the device" and won't be able to. Sometimes the phone goes into roaming and when I call it sends me to Verizon Wireless Customer Service (not sure why on this)
Phone will receive service fine when set to Automatic or CDMA LTE. If I attempt to call a phone I will get "Your account is not authorized to make calls to this phone number" with a mans voice.
-Do I need to do something with Sprint to go forward?
SOLVED IT:
Had to enable the "GCF Setting" on the phone.
YouTube Video: "How to enbale GFC settings on any Samsung Galaxy " - This guide worked flawlessly.
Now all I need to do in order to have perfect service on this SM-G900P on AT&T is to enable the rest of the AT&T LTE Bands on it.
Hey, I know this is necro'ing but I hope you are still around.....
I'm in the same situation as this post right now...I have have a SM-G900P (Sprint Galaxy S5), now activated through Straight Talk, but my data doesn't work when using CM13. I was wondering more what you mean by your GCF settings and maybe some quick tips to get 4G/LTE while on CM (Preferably 13+). Stock Rom I get LTE just fine, but for some reason it gives me this *FUGLY* Creedo mvno app suite when I do a fresh restore of stock rom, and just the whole touchwhiz thing sucks in general. I'd much prefer CM or any other custom ROM that cuts out the BS but gives me data.

no worries about necro'ing a thread, im not sure why some folks get bent out of shape about it :/ anyways, what service provider are you using via straight talk? they use all of the major 4 (vzw, at&t, tmob and sprint)
the basic answer to your question is APN settings. did you ever have data working with str8 talk? if so, your gcf settings dont need to be fiddled with, if not, then you have some tinkering to do. not at all difficult really, just some button presses

Well, the only band that identifies when I actually have a working data connection (tops I get is 3G) says Sprint. So I think that's who they're routing me through. I'm not a total rookie when it comes to this, but I don't know how to change the radio bands outside of what apps like Radio Switcher do (which actually just gives me a short cut to quasi-service mode settings in CM).
I get the cell data to read LTE on stock, but it's gross touchwiz and it never seems to get GOOD signal, two bars of LTE was the most in Milwuakee suburbs, an area I'd assume would be swimming in 4G/LTE. I'd much rather use CM for the customization (or any more "purer" android ROMS). If I select CMDA auto PRL I get a solid 3G and all voice/text/data services work. But any other option that includes LTE drops my data entirely.
Edit: I just realized I repeated myself lol. I've made a few posts on various forums about this. Kind of forgotten what info I've provided where. Sorry for the redundancy.

Edit: I just realized I repeated myself lol. I've made a few posts on various forums about this. Kind of forgotten what info I've provided where. Sorry for the redundancy.

i dont have any experience with the sprint flavor of straight talk service, but it should be on the same LTE bands as normal sprint. shouldnt have to monkey with anything tho. ill have to look more when i get home

Well, the only band that identifies when I actually have a working data connection (tops I get is 3G) says Sprint. So I think that's who they're routing me through. I'm not a total rookie when it comes to this, but I don't know how to change the radio bands outside of what apps like Radio Switcher do (which actually just gives me a short cut to quasi-service mode settings in CM).
I get the cell data to read LTE on stock, but it's gross touchwiz and it never seems to get GOOD signal, two bars of LTE was the most in Milwuakee suburbs, an area I'd assume would be swimming in 4G/LTE.

Ok, I reread your op and it said that you're using at&t. Are you sim unlocked? If not, Mr @stifilz, do you think you could hook this guy up? He has a proven track record of unlocking S5s
Just a heads up I'm not OP, that's @aventurer. I just happened to find a very similar situation. Probably changes your train of thought but for what it's worth in my situation, the phone sim came from Sprint originally, and the Straight Talk people said they use that sim to connect to the LTE bands.
I have been battling with this no LTE case for this Galaxy S7, BYOD. This is the official US unlocked version, and works with Sprint (on their whitelist), furthermore, my wife has the same phone rocking LTE with FP right now (BYOD as well, so on sprint network), so it's compatible with FP's service.
My understanding for FP byod (based on previous exp) is that if the phone was activated on Sprint network before, the MEID and the ICCID info is stored together, so even if BYOD process only ask for MEID, as long as you have the previous activated SIM, the ICCID info get carried together, so you normally would have no problem getting LTE.
This Phone was never activated on Sprint before, so when I first activated it BYOD, so no previous SIM info, but I plugged in a compatible SIM that was activated on Sprint network before (with another MEID though). My initial activation had problem (red bar on my account summary), had to email customer service to add this ICCID. Phone passed the hands free activation and all. No problem using the fp apps, phone, sms, cellular network worked (only 3G).
I then started to do all kinds of reset trying to get LTE connection. I have done,
1.##72786# carrier reset
2. Restore APN setting to default, clear cache, reboot
3. Matching all the LTE related parameter with a known LTE connected phone (my wife's GS7)
4. factory reset
5.Deactivate and then reactivate the GS7 (by swapping devices between two fp accounts)
Now almost three months now, I'm still facing the same issue. FP customer service has been helpful doing the routine checks, but not beyond the suggestion of PRL update/reactivation. The final solution they offered was to deactivate the account and the activate the GS7 with another byod account. I did this just today, by swapping another device in this account, and then reactivate the GS7 to that account.
My very first concern is if the ICCID info has been accurate (not missing or mistaken a digit), but I asked them to verify this at least three times, nothing came back as error.
Compared to my wife's same GS7 with fp, my phone is rather slow to establish the 3G mobile data connection, for example, her phone would almost show LTE instaneously after a reboot, but my phone would be at least after a min to show the 3g icon.
Can someone share some insights on what else I could do? I just could not think of anything else from my phone side to do. A note worthy thing is, when I helped BYOD my wife's GS7, I was in the same boat of needing to add ICCID via customer service to pass HFA, and then all the reset to get the LTE. I actually wasn't able to get LTE connection by what I did, shut off the phone with 3G connection, but next morning I turned on the phone, LTE was there. Along with me, I saw multiple users who had similar no-LTE problem report they were getting LTE same day.
I'm currently in the same situation. I've even tried adding the AT&T LTE bands as instructed on this thread and I'm still maxing out at H+. Anyone know how to enable LTE on unlocked Sprint S7? Any help would be appreciated.
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?
FYI, my wife's HTC 10 does the same thing. That would make two bad SIMs unlikely?

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.

Gotcha thanks, I'll give it a try! What's weird is our SIMs are only weeks old....

That's what I've been thru and got fixed. Hopefully it'll work for you too
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?
No idea why this started happening but every time I try to make a phone call, it'll hang up immediately. Checked all the settings and nothing has been changed or altered. However, I am still able to access the internet and send text messages. When I try to check my remaining voice and data by entering *777*1#, it'll say, "Connection problem or invalid MMI". It just doesn't make any sense. Contacted Airvoice Wireless and have yet to hear back from them. Has this ever happened to anyone else?
It must be a whitelisted model if it's running on AT&T's network. 4G VoLTE must be enable in hidden settings as well. A new sim card may be needed. AT&T stopped supporting 3G altogether.
Model whitelist (more may have been added since this doc release):

Yeah. My phone's model is whitelisted. I have the H871 variant of the LG G6. After doing some research, it would seem I need a new SIM card (as you mentioned). Nothing I have tried has worked so far. I even went as far as factory resetting my phone. And of course, it did not fix the issue. It's the SIM card. I did access the hidden settings but didn't really pay much attention to the 4G settings. I'm going to go back to that and take a closer look at those options. If there's a VoLTE option, that might do the trick.

That's the problem if it was running on 3G. My Note was running on 4G VoLTE when I got it so the sim card and settings were correct.
4G VoLTE must be enabled.
AT&T advanced tech support can probably help you. May take more than one call to get someone that knows what they've doing though.

I get my service from AirVoice wireless but have yet to hear back from them. What I found out by messing around in the secret menu is that when I choose WCDMA Preferred, everything works just fine. I can call, text, and access the internet. On that setting, 4G is displayed up top. What I found out was that any setting that displays 4G LTE will block my ability to make a phone call. If it says 4G, then I am fine. The problem with this is that everything will reset when I turn off my phone. So, it's pretty annoying having to set it every time. Is there any way to make my selection permanent?

Not sure. The carrier may need to do a reset on their end.
