Hello. I was wondering if unlocked (never carrier, never AT&T) Samsung Galaxy S7's have a reputation of working well on T-Mobile, including using Band 12 towers, and having T-Mobile's Wifi calling and VolTE.
Related to this was my question about a former AT&T unlocked Samsung S7 Active, which had all kinds of problems:
I am wondering if all this is avoided if the unlocked phone never was on AT&T.
