Got my new Nexus 6P, went to the Verizon store and got a nano LTE SIM. Ever since it's been plugged in, all features except LTE seem to work fine. Spoke to Verizon tech support and they see that everything seems to be setup correctly and the device activated in their systems.
One thing I did notice is that in the list of APN's, I have 6 of them. The one that says VZWINTERNET seems to have the right setup for what seems to be working for rest of the folks here. However, when I switch to using it, the signal is still stuck on 3G. Also after a couple of minutes when I look back at the APN list, it seems to fall back to the one that says "internet" which definitely seems to have the EvDo-rev A settings.
Has anyone experienced similar issue? Any suggestions?
I'm going to try to go back to the store again to try a different SIM card later today.
Quick update. First I tried switching the radio band first to Band 6, that's when it went to 1x and stayed that way. Then I switched it to USA Band and within a minute was able to lock onto LTE! Hoping it stays this way!
Said too soon. Side effect, no cellular connection available. Data transfer is at LTE speeds but can't make calls now
Here is the APN I'm using. Truth is I never changed a thing when I put the sim in. Factory reset it and find it a few minutes to get cellular working before messing with it. Sometimes it takes a while especially with a new sim.
Thanks static. That's the first thing I tried. Just let it be on 3G. Since nothing changed till this morning I decided to tinker a bit. For me the second to last APN keeps getting selected no matter how many times I switch it to the one you have.
Do you have another phone you can put the sim in and see if it works?
Nothing that takes a nano. I was able to get LTE to work just with data but it's pointless with no calling available. So at the moment it's like one or the other which is strange.
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.
I'm not sure if you are rooted or stock. I had a similar issue when I had an HTC M8. When I placed my Verizon sim card it would only connect at 3G speeds and not LTE. I tried to factory reset the phone through the menu multiple times but still no change. What worked for me was to go into the bootloader and then recovery mode and "wipe data/factory reset" with the Verizon sim card in the slot. After that reboot the phone and hopefully it will connect at LTE speeds. Obviously the reset will erase your phone so backup any important documents. Just a thought.

Were you able to get another sim card from Verizon? Wondering if that is the issue. Otherwise I'm not sure what would help. Sorry.
They allowed you to activate it on the phone itself? I brought in a borrowed iPhone 6 plus (because I was coming from a Galaxy S5) and activated it on that, then put it into the Nexus 6P. As far as I know, changing the APN doesn't fix anything except some MMS not properly transferring and has nothing to do with getting LTE itself.
If you have another phone that can be used on Verizon, test it out on that. Or try a new sim card.
I had the same issue, I tried my Sim in a different phone and LTE worked so then I decided to try my project Fi Sim in the 6p and that one had LTE. Then I put my Verizon Sim back and LTE worked. Maybe it needed a different Sim card to reset it or something.

I had this same issue after letting my wife borrow my phone one day. Come to find out she did a *228 to update the roaming for some retarded reason and it pretty much fried my SIM. A quick visit to Verizon and a new SIM solved it for me. Hope this helps.
Is mobile data set to Global or LTE/CDMA?

Ah I see, I wasn't aware that they already added the IMEI's to their whitelist. But I got my phone on 10/29 and activated it then, so I had to use another phone.

Hmm, I didn't even try because I read the stories about it, I guess people were saying it because the previous gen 6 was not whitelisted until a few months after release. I also didn't want them looking too deep into my account because I had upgraded and stayed on UDP through the loophole, so I didn't want to get booted off that.
So I got a replacement Nexus 6P, plugged the same SIM card in and voila, LTE and voice works. Thanks all for your suggestions. Seems like it was a defective device.
I'm gonna make a post here since NOTHING seems to be working. I'm a T-Mobile customer. Yesterday, I purchased a great condition nexus 6P from someone because my LG G5 is cracked and I was getting tired of it anyway so I opted to just buy a nexus instead of using my insurance on that phone. Everything is all good except for one major issue. VOLTE and WiFi calling just refuse to work with my sim in the Nexus.
I've called T-Mobile twice. I've factory reset from back up and reset settings twice. I've hard reset from stock recovery once. I've wiped network settings and restored default apns. I've manually changed the apns from what I see on Google, reddit and here. I've copied my apns from my LG G5 where VOLTE and wifi calling work perfectly fine. I've cleared cache. I've cleared the cache of the project fi and hangouts apps just in case there's something left over from the previous owner. I've gone into the *#*#4636 menu and tried a bunch of different stuff several times but no matter what I absolutely can not get wifi calling or VOLTE to work with TMobile on my nexus 6P. LTE it's self works perfectly fine for data.
Yes, all settings for wifi calling and enhanced LTE calling and VOLTE are turned on lol. I've tried the trick where you toggle wifi preferred on and off and restart the phone. Nothing happens. I don't even get a wifi calling reg error. It never shows as active in the data toggle in the quick settings are nor the status bar or dialer. It just isn't active. Same for VOLTE. I AM getting band 12. I can see it in the LTE discovery app. VOLTE just isn't working though. Whenever I make a call I can see LTE switching off and it switches to HSPA therefore making calls really difficult in my shoddy signal area at my house which is why I really need it to work.
I'm fairly certain I can root and install a ROM which will fix these problems but I don't own a PC. . I thought MAYBE the previous owner had previously had the phone rooted and tinkered with something somewhere that may have messed something up but that doesn't appear to be the case. Bootloader is locked and recovery is stock.
Can anybody help and tell me what in the world is going on here? I don't want to have to sell this nexus and revert back to my cracked screen G5. I would just switch carriers but I still owe money on the G5 so I was just gonna ride it out til I payed it off.
O and one last thing, after scowling google and forums for hours on end yesterday and today I did see one post mentioning something about this stuff being related to IMS provisioning and settings which are tied to a phones IMEI on T-Mobile and not the sim card and how that person simply called T-Mobile and got a hold of wifi calling technical support who was clueless but created a ticket for him and within 72 hours the issue was resolved. OK well I did the same exact thing and they refuse to create a ticket for me because it's not a T-Mobile phone and because according to them they are not allowed to create a ticket because wifi calling works fine in my G5 and therefore it's the phone and not them or their network lol. What a crock. I'm willing to bet if I put the sim in another unlocked phone with 7.1.1 and wifi calling fully available that it isn't going to work either. There's some sort of communication error going on between the sim being in this phone and their network it appears.
Check these screenshots out. T-Mobile is clueless

I can only suggest;
1) Find a PC and re-flash the latest factory images from Google. Both "fastboot flashing unlock" and "fastboot flashing lock" will wipe all data, so backup first. Also confirm it fully boots correctly after flashing before you re-lock the bootloader.
2) Get a new 3-in-1 SIMM from T-Mobile. You can use their web site to switch cards and give it 24 hours to be fully provisioned.
3) Confirm your E911 address is correct on T-Mobile's site and wait 24 hours after any changes for Wi-Fi calling to actually start working.
I HAVE THE SAME EXACT PROBLEM AS YOU POSTED!!! GONE THRU THE SAME PAIN. LOL I'll attempt the ticket thing to see if I get anywhere. Did you ever get it resolved?
EDIT:
My theory is that since the phone was used in Project FI, they specifically turn off this feature in the back end for the specific phones, by Imei or something since project FI uses T-Mobile as well.
EDIT 2:
they wont' create a ticket for me either. I guess I will just have to ride it out.
EDIT 3: I FIXED IT!! NEXUS 6P VOLTE AND WI-FI CALLING FIX T-MOBILE
I flashed back to android 6.0 Build#: MMB29N (I used the Nexus ToolKit 2.1.9: google it. BTW, your phone will be wiped, so backup first) VOLTE just started working with this version of android 6.0. Then I upgraded using the OTAs and now i'm on 7.1.1 build#: N4F260 with VOLTE and Wifi calling working as it should! I hope this helps someone out there!
For what it's worth, reverting to the build you mentioned fixed it for me on my two Nexus phones coming from Project Fi to T-Mobile as well! Thanks for the help!
You only need to install the radio from build MMB29N. I did this by downloading the build from the android website. Extract the radio from the zip and install it (I used nexus root toolkit but you can also just use flashboot if you wanted). This means you don't even need to revert your image and lose your data.

wish I had seen this sooner. cheers!
Had the exact same issue and this fix worked for me. Wasted a couple of hours with T-mobile (they were actually very helpful and debugged everything on their end to confirm the provisioning was good) and then 2+ hours with Google support. Actually had already filed for a device replacement which I canceled after finding this post.
I'm so glad I found this thread - my VoLTE and WiFi calling has not been working on T-Mobile and I'm anxious to give this a try. Numerous phone calls and support tickets with T-Mobile haven't resolved the issue. I don't know much other than how to follow detailed directions. My phone isn't rooted and bootloader is locked. I'm on Android version 7.1.2. Is there a way for me to install the MMB29N radio on my Nexus 6P without losing my app data given that my bootloader is locked?

Flashing the radio -sadly- requires an unlocked bootloader.
Did you resolve your problem?
In android 7.1.2 did you notice in Set preferred network type is set at " LTE/GSM/CDMA auto (PRL) "? 7.1.2 has been giving me issues with sms/mms. I noticed Android 6.0 has this set to correct T-mobile bands.
All works for me in 7.1.2. Make sure you don't download the Verizon version of the stock ROM. That was my issue why I couldn't have volte and Wi-Fi calling
I have been going through a weird issue on Total Wireless. When I use Android 6.0.1 and below, I have no issues with my service at all, everything works as it should. The issue comes into play when I use any Android 7.0 ROM, be it official or custom. Outgoing calls/4G data are fine, but I cannot receive any phone calls or send/receive texts. The only way for me to be able to receive calls and send/receive texts is to dial out once. After this, everything works as it should, that is until I reboot. Then I it goes back to the partial working state until I dial out again.
The issue persists whether I am using CDMA/LTE or Global Network modes. I have tried every single possible combination of starting with a fully working 6.0.1 firmware and upgrading through Smartswitch, with and without a full Wipe performed afterwards, doing a full 7.0 firmware flash. The issue is always present, and I am not sure if TW has issues with Android 7.0 or if there is a problem with my account. Their CS is absolutely useless in helping me with the issue, and our chats always end with if I can make a phone call, then the issue is resolved. They don't understand that the issue is still present, but it only crops up after a reboot of my device.
I have tried 3 different SIM cards and they have deleted and re-added/reprovisioned my device/number to their system but nothing seems to help this issue. APN is the usual TRACFONE.VZWENTP. It's really weird that it happens on two separate devices that I activate with my mobile number.
My only thought as to what it could be is maybe some weird provisioning error with the number coming from Verizon. Total Wireless doesn't have any type of VOLTE capabilities on their network, yet I was able to use a rooted Note 4 device and activate Advanced Calling/HD Voice and I believe Wifi calling as well and use it fine on their service. One oddity I noticed is that when the phone is in the initial 'Searching for Service' state on a fresh boot when I dial out while connected to Wifi, sometimes I will see Mobile Network Type change to IWLAN, whereas it usually says LTE. After dialing everything works correctly.
Any ideas on further troubleshooting steps I can take? If nothing can be done, maybe there is some way I can have a boot up script that makes a ghost phone call to any random number and immediately disconnects so I don't have to remember to dial out whenever I reboot my device?
Thanks
I don't have a solution yet, but you're not alone. I have a stock G935V (running Nougat) with Tracfone service running over Verizon's network. Whenever I start up the phone, the phone will indefinitely remain in a "Searching for Service" status until I initiate one phone call. Then the network instantly switches to "Verizon Wireless" and everything works correctly for as long as the phone remains on.
A long phone call with Tracfone and Verizon yielded no solution: They indicated everything is configured correctly in my account. Various replacement SIM cards didn't change anything either.
This issue happens with both stock Samsung S6 phones and the Samsung S7 phone in my household. All are running Nougat.
Any update here? My girlfriend's phone has the same issue since moving from Verizon to StraightTalk.

Tracfone tried, half-heartedly, to solve the problem by sending me 3 different sim cards. The problem never went away. I just got in the habit of initiating a call to voicemail whenever I restarted my phone.
The problem went away when I upgraded my S7 Edge to Android v8 Oreo.
I have flashed the Nougat "U" firmware on my Verizon S7 Edge. I had VoLTE, hotspot, HD voice when calling someone on Verizon (but the HD symbol doesn't show on my dialer, only on theirs).
Only issue was that. when I introduced the TW SIM, the APN was auto set for Tracfone (and it wasn't working), so I had to manually change it to the TotalWireless one.
Since then I had received the Oreo upgrade and the following security update... and it's still OK.
Hi guys,
Been into android modification since 7 years but gave up since my last 2 phones. So i got this unlocked at&t galaxy s7 in uae and it worked like charm, the network and coverage. I then started usingthe phone in pakistan too and it worked well even here. So one day i connected to gear vr so that i can initiate the oculus data installation as first time setup but the gear vr kept on disconnecting automatically. I have used it before too but never had problem. Then i rebooted the phone and i find that i have no signals at all even though my sim contacts are being displayed and there is no “no sim” message on statusbar even. But dont have any signals at all. I then inserted my sim to iphone and it was working perfect. Then i inserted different carriers sims to s7 but yet they werent working even. I then cleared the cache, factory reset, cleaned the sim slot and the sim , but no success. I left ky ohone turned off for days andeven drained battery 100% many times to calibrate and perform hardware reset but no success. I then sent the phone back to uae for repairing from my friend as i thought that the antennae were the one’s responsible but before he even thought of disassembling the ohone, he inserted uae sim and it worked perfectly. Call and data were working perfectly. Any idea what is the problem? Kindly let me know pleaseeee. Is there any problem with frequency? Like gsm or cdma? But the phone worked before. I tried to enter the settings of manually selecting networks but there was error popup “No service and signal”. Signal strength 0asu -113dvm

Forgot to tell, my phone has never been rooted, i even tried to enable/disable “Enable hd LTE features” but no luck. Its on 7.0. Dont recieve OTA. Not blacklisted either. Pakistan doesnt have CDMA. I have even noticed it recieving weak signals compared to my iphone when the phone was working ok. And my radio is showing to be off and when i turn it on from the dial code menu. It doesnt keep turned on and it turns off automatically. I still have the imei amd baseband version. Dunno what the issue is.
Kindly reply guys

Manually enter your carriers information you'll have to ask them or look it up online sure its easy to find they might even help you in store
Its not good for you to buy these US phones outside of the US because changing CSC to INS/INU/PAK could prove to be difficult being it was never supported by snapdragon G930A model but only exynos G930F although it's not impossible
/system/csc/others.xml is where your answers are waiting for you unless you update to oreo then it'll be in /system/omc/cscfeature.xml and cscfeature_network.xml
You will need a root file manger to be able to see what I'm talking about then you will have to figure out what those "strings" mean
Unless you want to mod and figure out make your phone awesome just flash other US firmware that uses gsm network only i think ATT only uses gsm and you can root to debloat ect.
Here's a method for rooting
https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616/amp/
I'm sure there's people in your surrounding area that are into androids and rooting that understand and can help you figure things out if you know any one woth a G930F/G935F INS/INU/PAK thatd be awesome. If your imei number is truly gone from your phone its should still be on the back of the phone
I know this isn't the best help but you aren't the first post I've seen of Pakistanian with US S7 tryjng to figure it out.. idk if he ever did but if you learn you can help others as well
*note: when I say change csc I don't mean flashing firmware in odin, that is impossible. I mean porting it yourself with root like in the link below this one
*another note: I am not saying use the link below as anything other than an example because again that link was developed for Eynos phones and not your snapdragon so it probably wouldn't work but just so you have an idea of csc

Hi, I've seen where some users have reported success getting VoLTE to work on the OP 6 on AT&T, but I have not had the same success in the OP 6T. I followed the same steps and enabled it on the phone, which now shows that it should use VoLTE when available. I have also spent many (painful) hours in the phone with AT&T trying to resolve this issue, all without success. Has anyone else been able to get this to work, and confirmed that LTE data is still presented when in a call?
Thanks in advance!
I have the McLaren version and with TMobile and I can confirm that it is using VoLTE see picture below.
"technically" I'm using at&t, but it's a tracfone sim via Straight Talk. I enabled it for both VoLTE & VoWifi, and the LTE one took off but the wifi version did not.
I DID notice the difference in call quality. Much better audio response.
Yeah. I'm on AT&T and I got VoLTE working. I just made a call and did a speed test while on the call. Everything indicated it was still on LTE.

I had issues with VoLTE when I first got phone. Read my post from another thread. Basically had to wait for AT&T to get my line provisioned correctly. Don't know exactly what needed to be changed/activated.
sharksfan7 said:
I got my 6T on Friday. Used @crowsnestitsupport's instructions for the *#800# trick to get the VoLTE & WiFi calling settings to show. Popped in my sim. Had LTE data but didn't get VoLTE & couldn't get AT&T's VVM app to activate. Called support, ended up giving them my IMEI and not surprisingly it came up as Unknown Device. Guy basically said until the system can recognize the device there was nothing he could do to get VoLTE & VVM working. However after I got off the phone, I quickly realized I no longer had any mobile data at all. Called back, spoke to another rep, and she tried for an hour to get my data back. She wasn't able to. She had to escalate the issue and said it could take 24 hours or more to resolve. I figured out that if I changed APN from ATT Nextgenphone to ATT Phone I could at least have some mobile data, albeit only 3G. Wasn't until Sunday afternoon that LTE came back online including VoLTE. I don't know what had to change to get it all working. Just glad that it is now. Still no WiFi calling but I don't expect to get that.

It's well documented that that doesn't work, doesn't change anything. I spent two years with the OP5 and 5t trying to get them to enable VOLTE, in about 12 different ways and it never worked. Either you were on WIFI or just really, really special.

I appreciate the feedback, just wish I could get it working on mine. As much as I hate the experience, I'm thinking it might just be worth going to the AT&T store just to get them to use my SIM in one of their devices just to get VoLTE working on the line (and/or verify it works on one of their with it already activated)

So, I can now confirm that VoLTE works on the 6T. Basically, the system requires HDVoice to get VoLTE working. The solution? I bought a $25 AT&T Prepaid junk phone and enabled HDVoice and WiFi calling on my SIM. After that, I switched the SIM back in to my 6T and it is now working.

I did, numerous times. They submitted my IMEI to enable the features, and I was told that everything was set up correctly. Upon their recommendation, I went as far as sending my brand new 6T back and buying another one. It didn't matter how many people I talked to, it didn't work until after I used the junk phone to first get it working on the line.

When I first swapped it worked and then stopped. I had to put the SIM back in the AT&T phone and again enabled VoWiFi. I then pulled the battery, turned on the 6T, and inserted the SIM. It's been working on the 6T since.
Sorry to revive an old thread, but has anyone found out exactly what to do to get this working?
VoLTE was working perfectly on my 3T, albeit the only way to make the switches appear was with the VoEnabler module in Magisk.. but once they appeared, all I had to do was turn it on, and VoLTE was up and running. I tried the same thing on this phone after putting my SIM in, directly from the 3T; it worked for a few minutes, then the status bar icon disappeared and calls drop my connection to 3G, then go back to LTE once the call is over.. so clearly it has turned itself can off.
I then put my SIM card into my wife's At&t branded Galaxy s9, and after a few minutes VoLTE was working, using my SIM in her phone. I popped my SIM back into my phone, VoLTE was back working... Except, just as before, after a few minutes it stopped.
One thing I've noticed, while working correctly, under the IMS Service Status menu selection in the *#*#4636#*#* dialer menu -> Phone Information, it shows IMS Registration: Registered. Voice over LTE: available... But once it stops working, it says not registered, and unavailable respectively...
Since there are apparently people who seem to have it working, what am I not doing?
Could it be that the phone I put my SIM card into, is currently in use by someone else; someone else who also is provisioned for VoLTE? But what would be the reason it decided to stop working on my 6T and not my 3T? I used the same procedure to trigger VoLTE working on my 3T, and it never stopped working as it is doing on my 6T.
We work opposite shifts, and I used my few minutes we see each other a day to put my SIM in her phone then back into my 6T, I didn't put it in my 3T, which I will do next time I see her.. just to see if the 3T will hold onto VoLTE; that way I'll know for sure if it's something the 6T is doing differently than my 3T, or if I just got lucky before...
Any input or suggestions are welcome..
Edit:
Called AT&T customer service, put my SIM in the S9 and said I was unable to activate either WiFi calling or HD Voice, yet my wife's SIM in the same phone works.. they said that for some reason, my SIM was apparently attached to a non at&t Galaxy s9, she changed the IMEI associated with my SIM card and it's all good now.
With AT&T, If i enable VoLTE, i did not see the "HD" icon when making call. If i disable VoLTE, i see the the "HD" icon. Why is it backward?

Click to expand...
Click to collapse
Opposite for me... The HD icon only appears when I have VoLTE on, as shown.. perhaps something to do with using 2 SIM cards?
I got volte and vowifi enabled and only problem is that i cant see the volte icon on status bar.
