Unlocked Version - Tmobile WIFI Calling

[Patriots1959]

Does anyone know if the unlocked version will work with Tmobile WIFI calling?

I don't have one but it's not likely that it would work. T-Mobile generally doesn't support WiFi calling on unlocked Windows Phones. They only do that for their own phones.

What T-Mo does...

Android and iOS have an app for T-Mo WiFi calling. WP does not so they put it in the firmware.

Last I heard, you can flash the T-Mo version to the unlocked via WDRT and that would get you there most likely. However, anyone who flashed an unlocked over to T-Mo is not able to revert to unlocked firmware.

YMMV

Actually I believe T-Mobile whitelists devices to work with wifi calling, since it's actually baked into the OS these days on iOS and android.

LOL it has been awhile since I used T-Mo.

On iOS, it is, it detects it when you put in the SIM. On Android, not so much, it's phone dependent. Some OEMs do the certification with T-Mobile, some don't. It's not exactly an Android given.

For Windows 10 Mobile? Not sure on T-Mobile. However from my perspective and what I know so far, if it is anything like AT&T then it would involve Carrier specific SW or baked in settings for the ROM on the phone and a white listed subset of devices (Certified IMEIs) from that OEM for the carrier. However AT&T won't even go that far yet. We can get VoLTE services but Wifi Calling is excluded.
