Samsung Galaxy Note20 Ultra 5G

Android 10.0

I can't make voice calls on my Samsung Galaxy Note20 Ultra 5G Android 10.0

Cause 4 of 12: 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 make calls.

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