Are you sure that your phone is unlocked for use on any network and also compatible with Irish frequencies?
What happens if you do a manual search for networks?
Can you see and connect to 48?
If not then what happens?
Any error messages?
In some cases iPhones need to be activated on a new network and this involves the iPhone silently sending a text message to a UK activation server.
This will fail silently if you don't have cash credit on your account to pay for the UK/international SMS.
So maybe put €1 cash credit on your account, switch the phone off and on again, wait a little while, and see if that helps.
You can check what phone number is associated with your account via your My48 account:
If you need to contact 48 support about this then see the links in my signature below.
