About Wi-Fi Calling
Wi-Fi Calling can improve your coverage
and allows you to make phone calls and
send messages over a Wi-Fi network
(when a Wi-Fi network is available).
Unless your rate plan provides otherwise,
Wi-Fi Calling minutes count the same as
T-Mobile cellular calling minutes on your
phone bill.
