Some issues may prevent WiFi from functioning correctly on your iPhone. There can be various reasons why WiFi calling on your phone may not function properly and keep turning off. For example, the WiFi calling setting on your phone is off, or you do not have a WiFi network connection. Your device might use a cellular network connection when the WiFi connection isn’t strong enough to make and receive calls. You have not yet installed your device’s most recent operating system or network settings.

Here Are Some Measures You May Take to Attempt to Resolve the Issue

1. Check Wifi Calling’s Status in Settings

The first thing to verify is that the WiFi calling capability is enabled. It is conceivable that you have not activated this feature, or that you accidentally disabled it. As device-dependent, the capability is not enabled by default on most phones.

To check out whether WiFi calling is enabled, perform these steps:

Select and open the Settings application on your Android device. Utilize the search box to research WiFi calling. You may also go to Network & Internet > Mobile network. There you will locate the WiFi calling option. To enable the function, click the toggle.

2. Restart the Router and Cellphone

If WiFi Calling is enabled but not functioning correctly, try rebooting the phone and router. It is usually a good idea if you have WiFi calling-related troubles or temporary phone bugs. It is tested that restarting your device will solve the majority of network problems. To restart an Android device, press the Power button until the available power options appear. Then, select Restart. This should resolve problems such as a momentarily slow WiFi connection.

3. Perform a Software Update Check

Apple provides small software upgrades to solve software issues regularly. This means that upgrading may restore WiFi Calling functionality if you are not on the most recent version.

Follow these steps to upgrade settings.

Tap General. Tap Update Software. If there is an available update, press Download and Install.

4. Switch Airplane Mode Off and On

Wireless sensors and antennas can no longer communicate with each other while the device is in airplane mode. Cellular data, Bluetooth, and WiFi connections are disabled when you activate Aeroplane Mode.

Control Center is the simplest way to toggle the Airplane mode setting.  Open it by swiping up from the screen on phones with a home button or down from the top of the screen on phones with face unlock.

Tap the Flight mode button. Wait 30 seconds for the connections to terminate. Tap the Airplane button again to reactivate all connections.

5. Disable Mobile Data

Some users have discovered that if you “force” your iPhone to utilize a WiFi network rather than the cellular connection, WiFi Calling will function. This is because your iPhone has no other option when attempting to connect to the internet.

To deactivate mobile data:

Launch the App Settings. Select Cellular. Turn off Cellular Data. Hold for up to one minute. Reactivate Cellular Data access.

If this does not resolve the issue, you can try turning off cellular data for longer and switch it on again after you go.

6. Reset Your Phone’s Network Settings to Default

If you’re encountering WiFi Calling issues, resetting your phone’s network settings to default is one of the last things you’ll want to do. It’s important to note that after this action, you will have to re-join your WiFi network.

Remember to reconnect to any previously connected WiFi networks and make any necessary adjustments to your VPNs after doing this process. Reset your network settings by simple steps as follows:

Launch the App Settings. Choose General. Down the page, tap reset. Choose Restore Network Settings. Enter your passcode. Confirm the procedure.

7. Reset Your iPhone to Default Settings

Have you performed all previous WiFi calling troubleshooting steps, but the functionality is still not functioning properly? 

The final step is to restore your cellphone to factory settings. This will delete all data, which may eliminate any underlying issues causing WiFi calling to fail. Remember that doing this reset will permanently delete all data from your device. 

Conclusions

Several solutions are available if WiFi Calling is not functioning on your Android phone. You are now aware of how to validate that your carrier supports the functionality, repair any existing issues, and verify that it is activated. You may now make calls via WiFi using your phone.

Can Wifi Phone Calls Be Intercepted?

The good news is that calling over WiFi will never put you in danger of a WiFi attack.
