What Is Wi-Fi Calling?

Toggle Airplane Mode off.

7. Turn Off Cellular Data

Some users have found that if you can “force” your iPhone to use a Wi-Fi network instead of relying on the cellular connection, this will make Wi-Fi Calling work. That’s because there’s nothing else for your iPhone to use when it tries to connect to the internet.

To turn off your mobile data:

Start the Settings app.
Select Cellular.
Turn Cellular Data off.
Wait up to one minute.

Keep in mind that you’ll need to reconnect to all saved Wi-Fi networks and reconfigure VPNs after doing this. To reset network settings:

Start the Settings app.
Select General.
Scroll down and tap Reset.
Select Reset Network Settings.
Enter your passcode.
Confirm the operation.

9. Reach Out to Your Carrier

If everything is fine with your iPhone and your Wi-Fi network at home, the problem may lie with your carrier. Wi-Fi Calling must be supported by your carrier, so reaching out and explaining the situation may be the best route.

It’s possible that there is an outage in your area, or that your plan is not properly set up to have Wi-Fi Calling enabled.
