You'll have to contact Eir to see if they can do anything.
See here:
If your current SIM isn’t active and your unable to receive SMS to the number you want to keep, you’ll need to contact your old provider regarding your account. Your current number and SIM need to be active to move to 48.
Your number may no longer be available to port depending on how long "a long time" is.
If you need to contact 48 support about this then see the links in my signature below.
