Activate Wi-Fi Calling
Wi-Fi Calling lets your device make and receive voice
and video calls over a Wi-Fi Internet connection
when your 4G coverage is weak or there is no cellular
coverage.
Texts and multimedia messages over Wi‑Fi can also be
sent and received just like when you use these services
on a cellular network. For Wi‑Fi calling to work, you
need to activate Advanced Calling first.
To activate Wi-Fi Calling:
1. From a Home screen, tap
2. Tap Advanced calling.
3. Tap Activate Wi-Fi calling.
Settings
Apps > Settings.
4. Enter a valid emergency address. This will be used
whenever an emergency call is placed over Wi‑Fi.
Once the address is saved successfully, Wi-Fi
Calling is turned on.
•
Voice and video calls will now be able to go
over Wi-Fi when your cellular network coverage
is weak or if you don't have cellular network
coverage in your area.
Note: You must be connected to a Wi‑Fi network for
this feature to work.
