I can't make voice calls on my Apple iPhone 6s Plus iOS 15.2

Cause 1 of 9: Not sufficient network coverage

The network coverage may differ from area to area. In certain areas it may so low that it's not possible to make calls.

Solution: Try making a call later when you're in an area with better network coverage. View our network coverage map.
