Set up Wi-Fi Calling on iPhone

1. Go to the Settings app on your iPhone.

2. Tap Cellular, then—if your iPhone has a dual SIM—choose a line (below SIMs).

3. Tap Wi-Fi Calling, then turn on Wi-Fi Calling on This iPhone.

4. Enter or confirm your address for emergency services.

   Note: Emergency calls on your iPhone are routed through cellular service when available. In the event that cellular service isn’t available, and you have enabled Wi-Fi Calling, emergency calls may be made over Wi-Fi, and your device’s location information may be used for emergency calls to aid response efforts, regardless of whether you enable Location Services. Some carriers may use the address you registered with the carrier when signing up for Wi-Fi Calling as your location. When connected to Wi-Fi calling, your iPhone may not receive emergency alerts.
