Does the Lumia 650 do T-Mobile Wi-Fi Calling?

[Windows Central Question]

When you bring an unlocked Lumia phone to T-Mobile, you cannot use T-Mobile Wi-Fi Calling. (T-Mobile branded phones come with unique software required for T-Mobile Wi-Fi Calling.) Many users believe that Windows 10 Phone would solve this problem, because Windows 10 Phone contains a Wi-Fi Calling app.
The Lumia 650 comes with Windows 10 Phone preinstalled.
So the question is, if you bring an unlocked Lumia 650 (because at this writing there is no T-Mobile version of the 650) to T-Mobile, will Wi-Fi Calling work?
(Related question: If it does work, is there any special set-up required on T-Mobile to "activate" it?)
Thanks!

Nope, it wouldn't work. There are only a few unlocked phones that support WiFi calling, but none of those are Windows Phone/Mobile.

So, this means that T-Mobile USA does not recognize/support the Native Wi-Fi Calling that is part of Windows 10 Mobile?

Correct. In order for that to actually work, the carrier has to approve it.

The only exceptions are t-mobile branded windows 10 mobile phones such as the fierce xl by alcatel.
