Hi @chunk35
The issue could be one of several variables.
- Network Signal is poor.
- Cell Masts have issues with them.
- The sim card maybe failing.
- The person your calling / calling you might be having issues.
Does this happen in a particular area or everywhere.
Can you as a process of elimination try your sim card in another phone and then another sim card in your phone and then see what happens.
A person can reset their network connections via Settings > General Management > Reset > Reset Network Connections.
There is a diagnostic tool in your Samsung Members App under the GetHelp section.
A Samsung Service Centre can check out the phone for faults.
I wish you all the best.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
