Will unlocked phones work with T-Mobile Wifi calling ?
If I purchase an unlocked phone, for example an S22 Ultra unlocked version, will I be able to make Wifi calls on T-Mobile ? This is assuming I use a T-Mobile SIM with it, or eSIM, of course.
The reason I ask is that I have no reliable cell coverage at home. Neither 3G/4G/5G offer reliable signals in all places in my home from any operator. A T-mobile cellspot in-home LTE tower also does not cover my entire home. The only thing that works reliably is Wifi calls, using a combination of 5 wireless access points.
My current phone is a T-mobile version (Note 20 Ultra) and works with Wifi calls. I need my next phone to continue to work with Wifi calls. Some unlocked phones are available for significantly less than the T-mobile versions, for example the S22 Ultra version sold by Google on Fi is $700 vs $1200 on t-mobile.com . But will it work with T-mobile Wifi calling ?

How would I know which model is a U or U1 and who sells it ?
FYI, my current Galaxy Note 20 Ultra is a SM-N986U, not U1, and supports T-Mobile Wifi calling. It was bought from T-Mobile and unlocked my T-Mobile, though. It wasn't unlocked from the start.
