You'll need to post a bit more information than that if you want assistance from the Community Forum.
When were you able to make calls last?
What changed in the meantime?
What happens at the caller's end when they try to call you?
Any error messages?
Can you make calls, send/receive texts, use mobile data?
Do you have a connection to the 48 network - i.e. signal bars?
If not then if you do a manual search for networks can you see and connect to 48?
Do you have an active membership plan?
If you need to contact 48 support about this then see the links in my signature below.
