iPhone 6 or above.Does Wi-Fi calling require a newer device? I'm guessing it's not going to work on my iPhone 5.
unless you have no service it sucks at least on att its just as bad as the microcell its takes forever to place a call and then you are lucky if they can hear you when they pickup I keep mine turned off this is my experience with wifi calling
That's not been my experience at all. To the contrary, the call quality seems better since it uses HD Voice when connecting with someone else on VoLTE.
