Your post was blank @EamonnF7806 and the subject line doesn't really clarify your query.
If you want assistance from the Community Forum then you need to explain/describe your issue or question clearly.
When was it working ok last?
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 58?
If not then are you sure that your phone is unlocked for use on any network?
If you do get a network connection then...
Can you receive calls/texts or use mobile data?
What happens when you try to make a call or send a text?
Any error messages?
If you need to contact 48 support about this then see the links in my signature below.
