Sorry not allowed call this number - only on some numbers

[RobertO6998]

My phone will only allow me to call certain mobile numbers yet when i try to ring someone else , i am being told "sorry you are not allowed to call this number" , just wondering how this could be fixed? All numbers working fine before I joined 48.

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.
