When was it working ok last?
Did anything change on the phone in the meantime?
E.g. software update, settings changes, factory reset/restore, returned from roaming abroad (including Northern Ireland), new phone handset, etc.?
If you do a manual search for networks can you see and connect to 48?
If not then what happens?
If you need to contact 48 support about this then see the links in my signature below.
