When was it working ok last?
Do you have a connection to the 48 network - i.e. signal bars?
If not then what happens if you do a manual search for networks?
Can you see and connect to 48?
If not then what happens?
Any error messages?
Assuming that you do have a connection to the 48 network...

What happens at the caller's end when they try to call you?
Any error messages?
Do you have an active membership plan?
Can you send/receive texts?
Is mobile data working for you?
Is your phone unlocked for use on any network?
