What sort of number?
Membership/add-on call allowances only cover calls to Irish mobile and landline numbers.
And calls to Northern Ireland landlines dialled using the 048 rather that 0044 prefix.
Some other calls only work if you have cash credit on your account to pay for them.
If you need to contact 48 support about this then see the links in my signature below.
