WiFi Calling on US Tmobile - ZTE Axon 7 Questions & Answers

I can not find the option to turn this on in the Settings menu unless I search for it. After searching & selecting it, I can enable WiFi Calling. Unfortunately as soon as I leave that screen the option turns off. Can anyone else get the function to remain turned on after leaving the selection screen? I am using a Tmobile SIM card. Also on Z.A.D's ROM v3.

I don't think tmobile supports WiFi calling for our phone. But ZTE is working with them to make this happen

T-Mobile WiFi Calling hasn't been added yet.

Thanks. Since I could enable it, I was thinking it was ROM related. Weird that I can't find the option in Settings without searching for it.

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

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

Verizon only offers WiFi calling for approved phones on there network. I do not have that option either with my 6p on Verizon however my wife's Galaxy S7 does.

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

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

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

Thank you so much! That is so great to know! I know that my setting for WiFi calling was there because I received the phone and played with it before I activated it and the setting was there. It was there when I was with AT&T and with T-Mobile.
I just found out what the problem/solution. It's the sim card. Today I purchased a T-Mobile sim card and even before it was activated, as soon as I popped it in my phone presented a notification about wifi calling and sure enough I checked the settings and the wifi calling option was back.
So if you have a 6p and the wifi calling option is not visible it's because of your sim card. Removing the wifi calling disabled sim card, rebooting the phone, reflashing the rom/firmware does NOT restore the visibility of the wifi calling option. The only thing that will restore the visibility of the wifi calling option is to insert a sim card that is wifi enabled.
I wish the good folks at Google or Huawei knew that the wifi calling setting's appearance or disappearance is tied to the sim card. It would have saved me a lot of work and headache
So having installed the sim from T-Mobile got you back the Wi-Fi settings back but when you put back the Sprint/Verizon sim did it remove it again or not? And if it didn't did Wi-Fi calling work on Sprint/Verizon? Or do we have to call and order a Wi-Fi enabled sim from our carrier?

Video calling?

I have the T-Mobile version, VoLTE is on, Wi-Fi calling is on, video is enabled....
No matter what network I can't video call. I've tried with friends on Verizon and T-Mobile, same phone.
I'm unrooted, on nougat, and beyond peeved an advertised feature won't work on stock device.
Has anybody gotten video calling to work?
Clearly nobody here either uses this feature or has this phone anymore.
Thanks for the total and complete lack of help, but I fixed it myself.
Wi-Fi calling must be enabled and activated in someway in order for this feature to work. I had to force Wi-Fi calling on and preferred, then changed it to cellular preferred.
I had video calling it was working then I updated my phone and now it's gone:/ how can I get it back?

How do you for wi-fi calling on?
Whenever I try video calling someone, I can see myself on the screen but the other person isn't showing up. The other person says it's the same on their end.

Wifi calling disappeared

Thank you

j730f/ds wifi calling problem

As I mentioned on the titile, I am facing a problem when I try to use wifi calling feature. There is an option on the scroll down menu, but when I tap it nothing happens. And the color of wifi calling is lighter than the others. I tried to open the menu with an app, but it showed empty. Is there a way to make wifi calling work?
Phone bought from Bulgaria. CSC code is ROM (Romania). Phone was sim locked, but lock was removed by using the method from instruction manual. Mobile operator supports wifi calling(feature works normally on an iPhone5s).

AT&T LG G6 Keeps Hanging 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.
