What is a UAC code?
Who is asking for this?
You shouldn't need any code to port your number from 48 to another provider.
Other than the porting security code sent by text to your phone with the 48 SIM still installed and working in your phone.
This verifies that you actually own the number in question.
Are you sure that you're inputting the correct account type.

If you need to contact 48 support about this then see the links in my signature below.
But you might want to contact the other provider's support to ask them for clarification on this UAC issue.
