    Hello All,

    I just switched from ATT to T Mobile and kept my iPhone 6+.

    I had ATT unlock my iPhone last week and got the "congratulations your phone is now unlocked" message in iTunes once i got the go ahead to restore.

    Everything works as expected, although i don't have an option for switching on WiFi Calling anywhere.

    I restored, as new, from back up (both) updated, etc....but no luck.

    Does it mean i need a T Mobile iPhone in order for this to work?

    Any help is appreciated, thanks!

    The AT&T iPhone 6 and 6 Plus versions are the same as the T-Mobile ones.

    Where are you checking for the WiFi calling option? Have you checked Settings > General > About to see that T-Mobile is listed there as the carrier version and there are no new updates? Have you tried resetting network settings? Perhaps take out your T-Mobile SIM and put it back in?
