If you’ve just finished setting up your new iPhone and haven’t been able to get Wi-Fi Calling to work, you’ll need to confirm that it’s working in iOS. To do that, open Setting application and select Mobile. Then tap Call over Wi-Fi and turn on the switch next to it Call over Wi-Fi on this iPhone (if disabled).

Enable Wi-Fi calling for other devices
Your mobile carrier may also allow any iOS or macOS device where you’re signed in with the same Apple ID as your iPhone to make calls over Wi-Fi. If you can’t do that, you probably haven’t activated the relevant settings.
On iPhone, go to Setting > Mobile > Call over Wi-Fi and turn on the switch next to it Add Wi-Fi calling for other devices.
Then, going back to the previous screen, tap Calls on other devices and toggle the switch next to each Apple device on which you want the feature to work.
Try restarting your iPhone. That often helps with minor issues that prevent features like Wi-Fi Calling from working properly. However, since iOS doesn’t have a direct option to restart the device, you must manually turn it off before turning it back on.
To do this, visit Setting > Shared > Turn off and slide Power icon to power off your iPhone. Then press and hold Edge to restart it.
Eject and reinsert the SIM
If your carrier supports Wi-Fi calling but you can’t see an option to enable it, try removing and re-inserting the SIM in your iPhone. That usually works as a quick fix to make it visible.
Use the SIM eject tool or a bent paper clip to remove the iPhone’s SIM tray. Then, restart the device before re-inserting it.
Update carrier settings
Your service provider periodically releases updates that address bugs and introduce new features. iOS automatically installs them. But if it hasn’t applied the latest update yet, you can install it yourself.
To do that, visit Setting > Shared > About and wait up to one minute. If you receive a Update carrier settings prompt to request an available update, tap Update.
