I have an unlocked Galaxy S7 Edge (SM-G935U). My carrier is Total Wireless (Verizon MVNO). I recently got a new office at work, and the Verizon coverage in this part of the building is terrible. I use wifi for data but cellular calling basically doesn't work at all.
I've been looking at other networks, and I'm leaning toward T-Mobile or MetroPCS, one of the reasons being they have wifi calling and the wifi at my office is plenty fast. I checked in settings to see the wifi calling option, but when I go to settings > connections > more connection settings, which is where the wifi calling setting is supposed to be, there's nothing about wifi calling.
I had a thought that maybe the wifi calling option isn't there because my current carrier doesn't support wifi calling, so I contacted Samsung support. I asked if I get a SIM from a carrier that supports wifi calling, would the wifi calling option be enabled. They said that unlocked phones don't support wifi calling at all.
This confuses me, because this thread mentions some people were able to use T-Mobile wifi calling on an unlocked S7/S7Edge. But that thread is older, so maybe for some reason wifi calling was removed from the unlocked S7 Edge with the Nougat update?
I suppose the only way to find out for sure is to get a T-Mobile or MetroPCS SIM and see what happens. But is anyone able to shed some light on if this is even worth trying? I suppose it's also worth trying out just to see if regular cellular calling on T-Mobile might be fine at my new desk, but hopefully there's some way to do wifi calling.
Unfortunately I think you need the sm-g935f to get t mobile wifi calling. Don't think it was ever achieved on the U models
I had an s7 edge from T-Mobile (SM-G935T) but I flashed the unlocked firmware essentially making it a SM-G935U and I had VoLTE and Wifi calling working with no issues. It was about a month ago, so it was on Nougat. I would expect no issues with an actual SM-G935U on T-Mobile.
Well, I answered my own question. I switched over to the T-Mobile 10 GB $50/month prepaid plan and when I changed SIMs the phone gave me a "reconfiguring your device for new SIM card" message. Wifi calling is now active.
Also, this is a list of phones that support T-Mobile wifi calling. I probably should've checked here first.

My phone is MHA-AL00C00 and I want to use VoLTE in Rogers network. But the menu of volte is missing and I heard some body using C636 and enabling Volte in US T-Mobile networking. So I re-brand my phone to C636B191. But still there is no VOLTE menu available. Then I used QuickShortcutMaker to enable WIFI calling setting anyway. Then I upgraded to Andorid O(MHA-L29 8.0.0.0.360(C636)) and I found Volte menu is available and it is enabled. But the real phone call is still back to 3G and there is no VOLTE icon in status bar. So I used another SIM card with VoLTE enabled in Iphone 6+ and I found there IS VOLTE ICON in status bar. Please see the attached screenshot and I placed a call and it didn't switch to 3G so it is real VOLTE call. But unfortunately this icon is gone after a while. I guess the Mate 9 phone is not VOLTE certified device in Rogers network.

thought Mate 9 was not VoLTE capable, at least not the chinese version in US.

I played with Oreo (China version AL00) and came across VoLTE tab (see attached). But I was not able to make it display on status bar.

I saw that but does not do anything, still my phone is switching from 4g to 3g when I do calls, I know my sim has VoLTE activated if I used with my carrier phone works fine.

Did you call to Rogers? How they did comment this?
From Rogers forum somebody mentioned to contact level 2 support to add your IMEI to Rogers database then you should be good to use volte.

Afaik, to get working VoLTE phone must support this and mobile operator too. And they will turn support by request if they can do it.
Just chat with Rogers and this function is not enabled on my account. After enabled you have to update your emergency address and submit to Rogers. I have done this on a Rogers iPhone 6. Now I have volte icon always.

On Mate 9 ? No fallback to 3G when calling?

Yes. no fall back to 3G when calling. But it only lasts 2 hours and this VoLTE is gone again. Re-chat with Rogers agent and they said it is not working on non-Rogers phone even you are lucky to get working for a while.
Sad!
Update:
This morning I just found the VoLTE icon is shown on status bar. After place a call the call log shows it is a VoLTE call (It also indicates it is VoLTE call during the call)
It looks like Rogers remove VoLTE restrictions on non-Rogers phone.
If the IMEI on your account is VoLTE capable, then VolTE will work for non branded devices, as long as the imei doesn't change.
I have a S10+ that was bought from US Cellular that I am now using on Straight Talk with a TMobile sim. I had Wifi calling working just fine before I switched to the new Beta update. After switching back to Android 9 it now says "This is currently unavailable under the call settings for Wifi calling. I am at a loss. I live in an area were the cellular signal is spotty at best and need Wifi calling to work.
Anyone have any ideas?
Thanks

AT&T doesn't like unlocked phones so it's possible the option isn't showing up because of that. Many AT&T customers with unlocked phones have reported that they needed to contact AT&T customer service to get WiFi Calling or Volte working.
Currently using Airtel sim on samsung galaxy S8. I'm facing some network problem in my area so I can't able to make or receive a call due to this problem. So I decided to use wifi calling feature. Now I came to know that wifi calling feature is not available in that list which was published by Airtel. Then I contacted airtel regarding this issue. They said that my mobile phone doesn't support Wifi calling. Then I have searched wifi calling feature on my phone. Its available. The thing is I cant able to disable or enable it. (I have attached screenshot of it )
Then I just switched my primary sim to JIO for checking whether wifi calling is working or not. Happly it's working fine on JIO sim.
Jio is supporting wifi calling why not Airtel..?
OS Version : Android Pie one UI 1.0 (using Samsung original software)
is there any other way to unlock this feature .....?
I have an unlocked and rooted H910. It is my backup phone and I want to get it to work with a T-mobile mvno sim for wifi calling.
Calls and data work with the sim and the wifi calling toggle is there - but when I switch it on it spins and spins for a bit and then says failed.
I tried 10r stock and Alpha-Omega and they both do the same fail when the toggle is switched on.
I would download another ROM but am I chasing something that just will never work? Or is there a app or service that I can delete that ATT is checking for ATT sim before enabling Wifi calling?
Any tips are appreciated.
Thanks
Not sure if it matters to anyone - but I couldn't find an answer to this. I tried freezing a handful of ATT apps with Titanium Backup. I probably could have wrestled with that a little longer but I gave up. I now have an ATT MVNO sim and it all works fine. So I can confirm that the LG V20 works with wifi calling and VOLTE calling without much issue. (I did have to ask the provider to enable WiFi calling on their end - they made me confirm my 911 emergency address but then it just worked 10 mins later with a reboot)
So - if someone figures this out I am still interested in the answer!
Thanks for looking.
