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 ?

    Hmm...that would kind of make sense, but that would be too bad for me.  I just switched to Tmobile earlier last year, too.  Thanks for your input.

    FYI- I ordered a renewed unlocked version N20U direct from Samsung today for $700. Reg. $850 but they have $150 instant savings. Plus if you use Rakuten, you can get 3% back.
