Let me elaborate. The feature is specific to genuine T-Mobile subscribers (MVNOs like SimpleMobile and Family Mobile are out of luck). The program IIRC checks against the SIM to make sure it's genuine T-Mobile, and IIRC it connects to servers specific to T-Mobile at the backend.I want to use wifi calling on my AT&T s4, can I load Tmobile ROM into my AT&T S4 to use WIFI Calling?
thx

What if I use a T-Mobile Custom rom with a AT&T S4, Im a T-Mobile customer, can I still use wifi calling since i have it enabled it in my plan?

Yes as long as it is a TouchWiz Rom.

We have winners! A T-Mobile customer with an AT&T S4 can most assuredly use a T-Mobile TW ROM and take full advantage of WiFi calling... Otherwise, no.
So if I load a t-mobile ROM on at&t phone I should be able to use wifi calling. But does anyone know how to load t-mobile frimware on at&t note 3?

You have to be a Tmobile customer, because the Tmobile sim and a Tmobile TW ROM are both required to have Wi-Fi calling.
