Working fine for me in Dublin city.
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?
If you have a network connection then does anything work?
If not then what happens when you try to make a call, send a text, use mobile data, etc.?
Any error messages?
Do you have an active membership plan?
Has anything changed on your phone recently?
Software update, settings changes, factory reset, new phone?
If you need to contact 48 support about this then see the links in my signature below.
