Wi-Fi Calling on an iPhone allows you to make and receive phone calls using a Wi-Fi network instead of relying solely on your cellular signal. This is especially useful in areas with poor cellular coverage but a strong Wi-Fi connection.
How Wi-Fi Calling Works on iPhone
- When Wi-Fi Calling is enabled, your iPhone routes calls and texts over the internet via your Wi-Fi connection to your carrier's network, which then connects the call to the recipient as usual. This is not a VoIP service like Skype; it uses your regular phone number and carrier service but over Wi-Fi
- If your cellular signal is weak or unavailable, your iPhone automatically uses Wi-Fi Calling to maintain call quality and connectivity. If the Wi-Fi connection drops during a call, it can switch back to the cellular network using VoLTE if available
- Emergency calls are routed through cellular service when available, but if not, they can be made over Wi-Fi. Your registered address or device location may be used to assist emergency responders
How to Enable Wi-Fi Calling on iPhone
- Open Settings on your iPhone.
- Tap Cellular.
- Select Wi-Fi Calling.
- Turn on Wi-Fi Calling on This iPhone.
- You may be prompted to enter or confirm your address for emergency services.
- When Wi-Fi Calling is active, you will see "Wi-Fi" displayed next to your carrier name in the status bar
Additional Features
- You can enable Calls on Other Devices to make and receive Wi-Fi calls on your iPad, Mac, or Apple Watch using the same phone number, as long as the devices are signed in with the same Apple ID and have the latest software
- If Wi-Fi Calling is unavailable or turned off, calls will default to the cellular network.
In summary, Wi-Fi Calling on iPhone uses your Wi-Fi internet connection to send your calls and texts to your carrier's network, improving call quality and coverage in low cellular signal areas while using your existing phone number and plan
