I can't make voice calls on my Apple iPhone 11 Pro Max iOS 18

Cause 9 of 10: Not adequate network coverage

The network coverage may differ from area to area. In certain areas it may be 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.
