Your phone’s cellular network connection might just need to refresh and toggling the Airplane Mode on and off should suffice. Here’s what to do:

  • Swipe your finger down from the top-right corner of your screen to bring up the Control Center.
  • Find the Airplane Mode icon and tap it to enable the feature.
  • After at least 30 seconds, toggle the Airplane Mode icon again to turn it off.

2. Force reboot your iPhone.

This will refresh your phone’s system as corrupted cache files and data will be dumped out after the reboot. Often times, system cached and data hinder the phone from acquiring signal from the available tower resulting for the phone to show “No Service” error message. Here’s what to do:

  • Quickly press and release the Volume Up and Volume Down button.
  • Press and hold the Side/Power button until the Apple logo appears.

If this simple solution fails to correct the problem, try the next one.

3. Remove and re-insert your SIM Card.
