3- Remove the SIM Card:

The message "Not Registered on Network" may appear on your phone screen when you're trying to make a call because the phone can’t recognize or read the SIM card.

So, remove the SIM card from your phone and clean it well, then put it back in its slot and make sure you inserted it properly, and then wait. If the message was appearing due to a SIM card issue, it's likely that it will disappear and the phone will be able to connect to the carrier's network again.
