Make free calls thanks to Wi-Fi Calling.
A feature hidden in Settings → Phone, would allow you to call any number from home country for free, providing that you’ve enabled Wi-Fi Calling on your device, and connected to a Wi-Fi Network. This feature works on three carriers in the United States – Verizon, AT&T and T-Mobile.
Here is how to make phone calls without a cellular connection:
- Enable Wi-Fi Calling on your device. Go to the Settings App and Tap ‘Phone‘ → WiFi Calling. If you have an Apple Watch, the feature will automatically enable on the smartwatch.
- You may have to register your Emergency ‘E911‘ address at the carrier. This is your default address in which you are most of the time. It’s used as a backup in case of emergency if your device can’t ping cellular towers and Wi-Fi networks to determine exact location.
- Connect to a Wi-Fi network. You should see a ‘Wi-Fi’ sign next to the carrier name at the top of the screen.
Unfortunately, you can’t force use Wi-Fi calling on iOS. Unlike Android which allows you to set a default network to make calls, iOS only uses Wi-Fi networks when the cellular connection is weak or missing. Future updates for iOS may be adding new options in the coming years.
