When was it working ok last?
Did anything change in the meantime?
E.g. phone software update, settings changes, factory reset/restore, new phone handset, returned from roaming abroad, etc.?
Can you receive calls, send/receive texts, use mobile data?
Do you have a connection to the 48 network - i.e. signal bars?
If you need to contact 48 support about this then see the links in my signature below.
