Nokia 3595: Phone restricted

I was given a second-hand Nokia 3595 phone. Powering it up with the SIM card that came with the phone (and the previous owner's AT&T service, now canceled), it says "SIM card registration failed" but the phone still operates off-line. No surprises there.

I did expect it to work with my own SIM card, which does work with my Cingular service in my Nokia 5190. However, when I put it into the 3595 and power on, it says "Phone restricted [Undo]". When I select "Undo" it prompts "Enter restriction code:". Of course I know such code, so I can't even use the phone off-line.

What can I do now? I'd really like to use the 3595 with my Cingular service; it's nicer than my 5190 in many ways.
