What is WiFi calling?

WiFi Calling allows you to make and receive calls, MMS and SMS over a WiFi network.

How does WiFi calling work?

When Wi-Fi calling is enabled, your phone will automatically identify the strongest network available. This means, your call will route through a Wi-Fi network only if it is stronger than your carrier’s cellular network.

  • Calling and texting with WiFi Calling. You can call, text and send picture messages as normal - no need to download an app or plug anything in.

  • Leaving WiFi coverage. If you leave WiFi coverage and your phone cannot find a mobile signal, the call will drop and you need to restart the call somewhere with WiFi or Mobile coverage.

  • Remembering the WiFi network. It will automatically reconnect each time you are in range to a saved WiFi network. When there is insufficient mobile coverage, WiFi calling takes place.
