I have a Nokia 6061 and a Cingular Pre-Paid SIM card. The phone is not a Cingular phone, but takes Cingular SIM cards. When I put the card in, the phone reads it and registers it, and I am able to make and receive calls. HOWEVER, when I try to access the Web I get a message that says "Subscribe to packet data first". I am not sure how to do this. Please help, as I need to download a game build for testing purposes.
