However, there are different reasons behind, and it may imply to your region as every country has different telecommunication companies.

1Update Cellular Settings or iOS Version

Your network might have updated the carrier settings, but your phone could have made a mistake, so we have to update it manually. It is an easier process, so you have you take out the SIM card from the device and clean it properly. Put the SIM card back in the device after cleaning it properly.

  • Swipe down a little and then tap on “Carrier” to update the settings automatically. The carrier will give you an update pop-up automatically on the screen and then tap on “OK” to install it.

Your phone should have updated the carrier settings in a few seconds, and it will work normally. If this problem persists, then restart your device a couple of times to flush the temporary system files.

Apple is releasing a new iOS version every year, while it consumes a lot of time to create a stable environment for the previous versions. We encourage the iOS 13 or iOS 14 users to update the device immediately and ensure that you are not missing out on new updates.

2Turn on 4G VoLTE

Many telecommunication companies have switched to 4G voice calling and 5G network and millions of callers are depending on this technology. However, the iPhone is slightly different from the rest, and that’s where you have to perform manual actions for the Voice & Data to work normally.

Give the device 10 seconds, and it will start working again. If it doesn’t work normally, then restart the iPhone, and then check, if the problem is resolved.
