How can I tell if I am currently using Wi-Fi Calling?
You can tell if you are using Wi-Fi Calling by these symbols on the smartphone display:
Android: In the notification bar of the phone, the symbol for WLAN connections indicates when a WLAN connection has been established and the service is ready.
This symbol shows that Wi-Fi Calling is ready for use. Calls can be made via Wi-Fi Calling.
This symbol shows that Wi-Fi Calling is not ready for use. Make sure your phone is connected to the WLAN and that the Wi-Fi connection is strong enough.
