Need more info on unlocking Nokia 6620 phone

[dtm25]

After reading threads after threads of unlocking information, I still couldn't get my Nokia 6620 to unlock. I tried different versions of Crux calc, with Asic 5 and 2, but non of the codes worked. I did notice two weird things that I think might be the problem. First whenever I entered code #1 to #6, the phone would always display "Enter Sim Card". And second I have gotten "Code Error" more than 10 times, and my phone still works. I don't know if turning the phone off and on between the trials matters. My IMEI is I hope help is on the way.

Thank you all,
Dennis

Everyone,

I finally unlocked my Nokia 6620 purchased from AT&T. The dealer had to use a special device (dunno what it is called) to reset it. It took them two days to do it. The problem I had with it not accepting the unlock code might be because I tried too many wrong ones. In my case, the phone just stops accepting codes instead of disabling the phone.

ps. hopes this helps.
