    Hello people i just a simple question
    Do all iphone 5c,5s,6, and 6plus have wifi calling built in? If i get a Att iphone and unlocked it and use it with tmobile will it work? or one has to get one directly from tmobile?

    Yes once you put the T-Mobile SIM card in the phone the option for Wifi calling will show up.

    All iPhone 5C, 5S, 6, and 6+ that are unlocked will work with T-Mobile's WiFi calling. When you insert the SIM, it'll have you download a carrier update file which will enable WiFi Calling. The option is in the Phone options.

    don't know about others, but 6 and 5s works fine.

    man this is awesome, you can even text for free while you are on a flight.
