If removing the SIM-card does not help to solve the problem, you either need to replace your SIM card or hard reset your phone. Do not put back the SIM card before you have completed the next step.

If yours is an iPhone 7 or iPhone 7 Plus, press the Power and Volume Down buttons simultaneously and hold them until you see the Apple logo.

For iPhone 8, iPhone 8 Plus, iPhone X and newer models, press the Volume Up and release it quickly, then release the Volume Down button and release it quickly, and then hold the Power button until Apple log comes out on the screen.
