Are you following the activation instructions here?
At what point does it say that you need a mobile number?
You should only need that if you're porting your existing number from another mobile provider over to 48.
If you don't need to do that then the SIM automatically comes with a new 089 number.
If you need to contact 48 support about this then see the links in my signature below.
