To use Wi-Fi Calling, you must
first turn on Wi-Fi, connect
to a Wi-Fi network, and then
turn on Wi-Fi Calling.
When the Wi-Fi Calling feature is
turned on, your phone displays
the Wi-Fi Calling icon on the
Status bar.
To stay on a Wi-Fi call, you must
remain within range of the Wi-Fi
network. When your Wi-Fi signal
weakens, your phone will beep
and display a warning message
alerting you that your call will
drop if the signal gets weaker.
Wi-Fi Calling offers three connection options:
Wi-Fi Preferred: All calls are
made over an available Wi-Fi
network. If there are no available
Wi-Fi networks calls are made
over the cellular network.
Cellular Preferred: All calls are
made over the cellular network
unless the cellular network is not
available, then calls are made
over an available Wi-Fi network.
Wi-Fi Only: All calls are made over
an available Wi-Fi network. If there
are no available Wi-Fi networks,
your calls will not connect.
