Ever since iOS arrived, it is causing a lot of errors for iPhone users. Now after so many issues a new one I heard is No Service after updating iPhone to iOS 12. This is happening because of iOS 12 has a bug, or it might be possible that one of the carriers which you are using like AT&T or Sprint or Verizon or T-Mobile carriers are under maintenance.
We can’t judge what the main reason behind No service in after updating to iOS 12 is. However, instead of cursing the carrier or iOS 12 we better try some potential solutions that may solve this issue. The iPhone No Service issue also indication in the suburbs area due to the lack of coverage as well as after airplane mode, battery replacement, and after screen replacement.
You have never had iPhone NO service problems. Henceforth, you are worrying and thinking that the no service is the hardware problem (due to the component that has failed on the main logic board) or software bug.
