You'll need to post a bit more information than that if you want assistance from the Community Forum.
When was it working ok for you last?
Did anything change since then - phone software update, settings changes, factory reset, new phone, returned from roaming abroad, etc.?
Could Storm Darragh have knocked out services locally?
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?
Are any services working? Calls/texts/mobile data?
If you need to contact 48 support about this then see the links in my signature below.
