Steps to Fix “Call Failed” Issue on any iPhone

1. Check Network Coverage

One of the most common reasons for call failure on iPhone is poor reception. So, check if your area has a bad network signal and whether the issue occurs only when you’re in a particular area. If yes, then the issue is network-related, and you can’t really do much about it.

A quick reboot can solve most temporary glitches and bugs on your phone. So, hold down the power key and swipe the power icon to the right to turn off your iPhone. Then, long-press the power key to turn it back on.
