Several iPhone users have started reporting an issue where they are not having cellular service on their iPhones to make any calls, messages, internet, etc. No Service error appears on their iPhone screen when they open the control centre.
This happens when the user is not under the coverage area of the mobile network which is the main valid reason. Other possibilities are some software bugs/technical issues within the iPhone, network connectivity faults on the iPhone, problems with your sim card, etc.
Having these factors in our mind, we have come up with certain best solutions that would help you resolve the No Service error on your iPhone in the article below.

If you are facing any issues, particularly with the cellular network on your iPhone, it could be due to the sim card placed inside the iPhone. In order to fix this issue, we recommend our users try removing the sim card from the iPhone and cleaning it once.
To do so, you first have to take a pointed pin and insert it into the sim card holder on the side of the iPhone. This ejects the sim card holder from the iPhone.

After the sim card is cleaned, place it again on the sim card holder and insert it back into the iPhone. Now you will see that the service is back in action on your iPhone.
