Hi, I just switched from T-Mobile to AT&T and I know T-Mobile did not support wifi calling on unlocked phones, but AT&T says they do and they said they have it turned on, and everything on Sony's support pages says that I should have it, but the option to turn it on is nowhere in the phone app settings or the Android system settings. This is a problem in both Oreo and the Pie ota update I got last night. Is there any fix for having the option to show up? I really need it where I just moved to and if I can't get it working I'll have to get a different phone and I'm really liking this Xa2 ultra and hope it's something that can be fixed.
