Thank you very much for your help.
I tried both keys, but my phone says "Code Error".
What can I do something else?
And my "Nokia 1600" seems to be "Nokia 1600b" strictly.
Have I said you wrong model?
I can confirm something is different about Nokia 1600b speakout phones, I have tried two and they will NOT unlock using the online code generators and Cingular as the carrier.
Maybe they have a different carrier code than the unlock generators know about?
The 1100b's they have at 7-11 are not locked. Looks like they got wise and have locked it's replacement - the 1600b.
Hopefully some of you smart guys can figure this one out shortly.
