Wi-Fi Calling
Wi-Fi Calling is a free feature for T-Mobile customers using
this device with the new SIM card. Wi-Fi Calling is an
excellent solution for coverage issues in and around the
home or wherever cellular coverage is limited. Minutes used
while connected to the Wi-Fi network count against available
rate plan minutes.
For more information, refer to "Wi-Fi Calling" on page
