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.

You didn't provide any detailed information about your phone model, firmware or even a step by step description of how you did a factory reset. So we have no way of discerning whether you missed any essential steps or narrow anything down.
Nevertheless you have an odd problem that no one else seems to be reporting. Ergo the most likely explanation is odd settings or corruption on your phone. As a factory reset (clearing user settings) apparently didn't work, the most plausible remaining cause would be a cache problem or some anomaly in your system files.
To that end, try wiping the cache from recovery mode. If that doesn't help, then use Odin to write a full stock firmware to your phone to replace the system files as well. If your problems persist then open a support ticket with your carrier to look into your account configuration. The latter is unlikely though if the SIM works in another phone. So in as much as we can tell given the paucity of details, you should try replacing your system files with Odin. Also check your APN information.

I'm on AT&T and having the exact same problem. I switched from Verizon as AT&T has a new tower in my rural area for better reception. I have 3 bars in my home and when talking on the phone it goes up to 4 bars. No problem calling out. Purchased the new Samsung Galaxy S5 on 9/15/14.
Incoming calls go directly to VM. Sometimes the phone works as it should and calls and messages came thru in a timely manner.
Mostly the calls go to VM and text messages are delayed. Vm doesn't show up as having a vm for hours.
I have gotten a new sim card, exchanged the phone and the new phone does exactly the same thing, I am now past my 14 days so I am stuck with this phone unless I agree to a warranty replacement phone from AT&T. (Same phone S5)
I have has 4 cases with AT&T and nothing has helped. Last case will be resolved bu Oct 4.
I will try turning off WIFI while at home and see if that helps.
I have reset the new phone, did not help. I don't understand why with 3 bars I can't receive calls.
Calling out is no problem. Incoming doesn't work correctly. Any suggestions are greatly appreciated. Thanks in advance.

Friends of mine were at my house over the weekend and he had a samsung s4 and had the same problem after logging onto my wifi. It is the wifi causing the problem. I had an old modem and netgear router that we hooked up and then we were able to receive calls like you should. We switched out the modem/router combo on Sat to my older setup and my phone is still working normally! I called my dsl provider and told them about the problem as I just bought the modem/router combo from them recently.
They never heard of anything like this. I do find it hard to believe that the home wifi equipment disrutes the cell phone signal. But my phone is now working!!! Anyone ever heard of this or that can explain why this would happen I would love to hear about it.
I have been trying to get wifi calling with AT&T is working on my International S7 edge. I have made headway.
1. First of all I told AT&T I had their branded S7 edge and gave them an IMEI that will show up that phone. So I can activate my phone.
2. I have narrowed down the required apks to the following, but some are obviously for the Wifi Calling, and other's I am not sure. If people know what some of these apks do, please let me know.
3. I have used the Note 7 Port and flashed TTKG CSC selection and chosen the ATT CSC, we are still working on getting it working in the S7 and Edge CSC.
4. The following APK's I feel are related to Wifi Calling are.... If you can help me eliminate some that aren't. They are deodexed, and I have uploaded them, you will need to change the permissions to match the ones in the system folder.

Did you ever get this resolved? So far I can not for the life of me, get WiFi Calling working on my S7 Edge exynos. Basically throws an error stating the activation failed, and never brings up the screen to enter in my emergency contact address like AT&T is supossed to re-direct you to.
The activation fails because AT&T doesn't have an AT&T wifi capable phone on your account which then allows you to activate the wifi. I have two imei's that are linked to AT&T s6 and s7. I can give you the imei. Go to att tech support give them the imei and tell them to update your account to be able to get visual voice mail and wifi calling. After you do this, they will alow you to activate it. However I gave up after a while. If you flash the custom csc, you must do it before your phone boots up after a factory reset and flash a custom rom. I am waiting as I am on Nougat now, so until ATT updates it's apps again.

Thanks, although I'm a bit confused on the steps your outlining here. I assume you're stating that I'll need to somehow modify a ROM (in this case SAC's N7 ROM for S7 Edge Exynos), and inject an IMEI? I'm not entirely sure how to do that to change the IMEI (this would be my first time attempting to do that). Then I would reflash that image, and then re flash the CSC update to AT&T? Maybe I'm not understanding, but my iPhone 6 is on my account and fully capable of wifi calling. In fact we have 2 iPhone 6s on the account. What exactly did you give up on?
Hate to sound like a newb here (although in a way... I am), but can you step me through the process so I can follow your line of thought? Appreciate the help!
So first of all an Android WiFi Calling and IPhone Android WiFi calling are different you will need to tell at&t you have an AT&T branded Android phone that has WiFi calling. This will lead at&t to add the ability to add wifi calling on your account.
Have you rooted your phone and installed a custom rom? If so then you would flash ttkg84's csc package and choose att. Which will flash most if not all the files. I got all the way to confirm my address and enable wifi calling, but it never worked.
Do not insert another phones imei into your phone, you will brick it and will have a expensive paper weight.
I have given up for now and am waiting for a full release of Nougat.
PM my I can give you am imei to give AT&T to enable video calling, visual voice mail and give the ability to activate WiFi Calling, but it's not likely to work. Some things are still missing.
You may never get wifi calling working because at&t uses a slightly different method then everyone else. I think they will standardize with Nougat.

That's what I thought.... So what about the King of Nougat ROM that's lingering out there currently? I realize Nougat is still beta, but have you tried the beta?
I haven't tried King of Nougat. I am currently using Nougat? Are you on telegram?

So... Interestingly enough. I just got WiFi Calling to work this morning...
Basically, I did the following steps:
1. No SIM Inserted into Galaxy S7 Exynos - SD Card only
2. Reboot to Recovery
3. Wipe
4. Download and Install SAC23's Full n7 ROM located here: http://forum.xda-developers.com/s7-edge/development/rom-n7-rom-port-romcontrol-t3430358 - I did the V8 Debloated version
5. When prompted - Wipe Dalik
6. Insert SIM Card from AT&T iPhone (ensured WiFi Calling was turned OFF on the iPhone prior to removing from iPhone)
7. Reboot first time into N7 ROM
8. Go through the setup and connect to a WiFi location that you know WiFi calling works at.
9. Download a browser (Chrome or whatever) at a minimum
10. Eat a Bacon, Lettuce, and Tomato Sandwich :good:
11. Reboot to Recovery
12. Flash CSC for the N7 located here --> http://forum.xda-developers.com/note-7/development/utility-flashable-csc-selection-v1-0-t3450911 - Grab the CSC snapdragon the Exynos zip
13. Reboot
14. Status bar will indicate VoLTE enabled up at top eventually.
15. Try going to the pull down from the top, and clicking WiFi Calling option a couple times.... no dice.
16. Try going to the phone app --> Click Settings --> Note WiFi Calling is off --> Try clicking it on a few times.... you'll get an adroid app stopped working.
17. After sitting on this sceen for a few minutes, note the VoLTE dissapears, and the icons on the phone app screen (The Call Start Button and the Call End button) switch to WiFi magically.... Try making a call with 0 zero cell reception, and indeed, the call is being made through WiFI on AT&T's network.
Now.... I have absolutely zero idea what's going on with the VoLTE icon disappearing.... and the WiFI calling suddenly working. If you reboot the phone, the same thing occurs. It starts in VoLTE.... and then eventually disappears, and eventually after a couple of minutes being connected to a WIFI connection, switches auto-magically to WifFi calling.
I'll take some screenshots.

Followed the method above using Superman 1.16 and CSC selector 1.86.
Haven't been able to test wifi calling since I haven't found an area with wifi and no cell reception, but so far everything looks like it's working.
Important to note that the AT&T account probably does need to be provisioned for a G935A rather than G935F, which is done by reporting a G935A IMEI to AT&T (and not changing it on the device itself) as mentioned previously.

Hmmm, gotcha.... but if you report a G935A they typically want you to power off and power on the phone to check the provisioning while on the phone with them. And what happens if someone calls in and then tries to re-provision the same IMEI on another account? What happens to my SIM in my G935FD? Thanks!

Far as I can tell they don't check IMEIs against different accounts.
I can't say for sure, but I haven't had an issue as my phone has a different IMEI (or IMEIs--G935FD) than the one listed on my account (which reads as a G935A).
In short, asking AT&T to change the IMEI on the account hasn't affected or changed the IMEIs on my phone, or caused any problems.
As far as provisioning, I told them I was on the phone, so they called me back a few minutes later and didn't report any issues or discrepancies to me.
It'd be just as easy to tell the rep the phone isn't available though, so just ask them to change the IMEI and you can call them back later if there are issues if that's a concern.
Looks like great news. I was happy I was able to activate my 935F via AT&T (I gave them the actual IMEI and they activated it). I'm on Superman ROM and flashed ATT CSC. I get visual voicemail and the WiFi calling button, but it doesn't actually work. I'll see if I can get a valid 935A IMEI and ask them to activate again. Hopefully that will do the trick. I get a horrible signal at home, and the 4G/LTE icon is constantly flickering on and off... AT&T Video call option shows up in settings, but won't turn on... no wifi calling setting in the settings menu, just the quick settings button.
Any guidance appreciated!

My v20 drops all calls between 2 and 4 minutes in, and usually around the 3 minute mark. The call drops, signal goes to zero, and a moment later I get a toast message saying "Loading SIM card contacts..." and then I can immediately dial back in.
WiFi calling is disabled, though the setting being on or off doesn't seem to make a difference. I've cleaned the SIM card and added tape to the back to ensure good connectivity - no change. I also went to T-Mobile and they replaced my SIM on the spot but it immediately happened again in the store and in front of the clerk when we tried a call. They've suggested a warranty exchange.
One interesting thing I've found though is that disabling VoLTE calling fixes it entirely - it no longer drops calls, but of course there's no HD voice and I can't use band 12 and they're already cutting back on HSPA coverage.
Haven't found anything else useful via Google or XDA. Even with VoLTE enabled there are no data drops, VOIP calling via hangouts works fine. Anyone have any ideas short of a full exchange? Not rooted and while the LG backup app is pretty good, I really don't want to go through the day-long process of restoring everything if I can avoid it.
Hey there! I had the same issue, exchanged the phone for a new one, and STILL have the same isssue! Did you ever find another fix? This is so annoying and I cant believe a bigger deal isn't being made of it.
Something wrong with ur

Been owning V20 for about 5 weeks now. The first 3 weeks were pleasant until I started seeing dropped calls. Disabling VoLTE did not help. Changing sim card wouldn't help either.
I'm having similar issues H915 Freedom Mobile.
Was roaming on AT&T in the US when I first did the update. And everything was fine till I was home and on Freedom.
When Wi-Fi calling is enabled. It makes no difference if mobile preferred or VoWIFI preferred is selected. It enables either way after reboot or turning Wi-Fi adapter off and on again.
Incomming calls frequently don't come through regardless of whether vo wifi is on or off. Texts same problem. And persists sometimes on cellular and sometimes on VoWifi.
Get SIM errors, signal drop constantly. And have tried everything I can think of to rectify the issues with zero success.
Anyone with Freedom having similar issues? Or any suggestions I might not have thought of that may be the the cause?

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.

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
Hello all,
Got my G955N in my hands. Followed the threads here to get TWRP installed, used it to install Batman ROM, then used TWRP to flash the AT&T CSC as my provider is AT&T.
In my pull down menu I do have the option for WIFI calling, however whenever I hit it, it fails (seems I can't post pics, so here is the text I get: "Loading, this may take a few moments" then it blinks a few seconds in and repeats. Then it goes to "Please try to set up WIFI calling again later."
I know it's an issue with my phone specifically because my wife's AT&T iPhone7 has WIFI calling working fine (not an ISP issue at home) and I swapped her SIM into my phone and I still got the same error. So it's something with the phone and not likely an account level issue (although maybe? Who knows at this point?)
Also, when I enter the testing menu, I see that "Data Service: Disconnected" which I'm not sure is right? Also, VOLTE Provisioned is not selected, however each time I do select it, it immediately goes back to deselected the moment I navigate away from the testing menu. I can reselect it all day and it still goes back to deselected the moment I move out of the screen.
I've read until my eyes bleed and tried just about everything I could find to try and no joy.
Any ideas?
P.S. got pics if anyone wants me to email them to you for clarity. Guess I'm too new here to be allowed to post pics
To follow up:
Turns out it was an account based issue. Seems AT&T tries to verify the IMEI when attempting to use Wifi calling. So unless registered in the network, it isn't going to work.
And the kicker is, AT&T won't allow Wifi calling or other services with any phone they didn't sell. You can toss in your SIM and use calling, but they won't activate other features if you try to bring your own phone.
So I spent yesterday switching to T-mobile and am now fully functional with all the features of my phone working as they should. AT&T lost me as a customer.
