I can't make voice calls on my OPPO Find X9 Ultra 5G Android 16
Cause 1 of 12: Not sufficient 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.
