What do you mean by "48.ie service"?
The website/My48 account or your phone for calls/texts/data?
I'll assume the latter.
Do you have an active membership which is necessary in order to use network services?
Does your phone connect to the network?
If you do a manual scan for networks can you see and connect to 48?
Did anything change on the phone? Software update, factory reset, settings changes etc.?
If you need to contact 48 support about this then see the link in my signature below or email them at support@48months.zendesk.com
