WiFi calling allows you to make and receive calls over WiFi instead of using your mobile network. This is useful in areas with poor mobile coverage or when traveling abroad.
Enable WiFi calling on your iPhone
- On the iPhone go Settings
- Select Phone (halfway down)
- Under CALLS select Wi-Fi Calling
- Slide to enable
- Select Enable on the popup Enable Wi-Fi Calling message
Once enabled, your iPhone will automatically switch to WiFi calling when you're connected to a WiFi network and your mobile signal is weak.
