So then the answer is more or less “Maybe but it depends on where you are” I guess Re: does Xiaomi 12s ultra work with T-mobile? I'm not so sure that phone calls wouldn't work. The 12S Ultra does have the 2, 4, 5, and 12 bands for the 4G network, and I'm able to make calls over VoLTE on my Mi 9T which only has the 2, 4, and 5 (no 12, and no 5G at all)
