Mine is also from Cingular (USA) and my imei = 358804007504361 I have tried some of the unlocking programs to generate a code, but none seems to work. I am wondering if maybe the phone is "hard locked"?? How could I tell? I am trying to unlock it so I can use my current T-Mobile service. If I put the Cingular chip back in it, it still boots up normally.
Model: Nokia (6102) IMEI: 358804007504361 Network: 31017000 #pw+124 934 447 146 123+1# #pw+713 910 336 056 206+5# #pw+150 334 270 740 027+7# If it says "cannot undo restriction" when you type these codes then it means the mobile is hard-locked.
Still no luck... it continues to say the restriction is on, and to insert smartchip... It does not say "Cannot undo restriction" however....
