I want to port my new number to old number

If you want to port a number from your old mobile service provider to 48 then follow the instructions here:

"port my new number to old number" doesn't really make much sense. 

You'll need to explain in more detail/more clearly what exactly you mean by this. 

If you need to contact 48 support about this then see the links in my signature below.
