What exactly do you mean by "no coverage"?
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?
When were things working properly for you last?
Did anything change in the meantime?
What exactly do you mean by "account in credit"?
Do you have an active membership plan?
If you need to contact 48 support about this then see the links in my signature below.
