After more than 15 years covering everything Apple, it’s with a heavy heart we announce that we will no longer be publishing new content on iMore and the iMore forums will be closing as of November 1st, 2024.
I am not able to receive or make calls out on my phone. What should I check?
Have you tried a simple reboot/restart of the phone? That is hold the home button and power button at the same time for about 10 seconds until the Apple logo appears. Also you might try turning on airplane mode waiting 30 seconds then turning it back off, this will cause your phone to try to reacquire its signal.
