I can't make voice calls on my Apple Watch Ultra 3 watchOS 26
Cause 1 of 7: Not adequate 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.
