    Does WiFi calling on TMO require the SM-G950T (T-Mobile branded) phone?  What happens if I activate an unlocked international model like the SM-G950F or FD on T-Mobile?  Will WiFi calling work?  In other words, is WiFi calling dependent on some additional software that is only present in the SM-950T?  Can the ATT model be brought over to T-Mobile and still have WiFi calling work?
