Nokia 1600: any way to find out the default security code?

[dynexxx33]

I recently damaged my phone and needed a cheap unlocked device so I could hold off for a hardware upgrade. I purchased a used and unlocked Nokia 1600 off Kijiji that is causing me problems. The so called unlocked phone is asking me for a security code, and no matter what I do, I get the same message "code error" I have tried the standard code (12345) and visited countless sites devoted to unlocking phones in search of this phones code. The original owner says he never locked it, and Rogers (my service provider) says it is not my SIM card. Any suggestions?

I think it is the service provider. To justify this you could use the simcard in a different Nokia Unlocked phone and see if it gives the same error. I think I would give 0000 a try too. But, that is your best bet, but Rogers.

The security code is related to the phone, not the sim. The default is 12345 for Nokia phones. If it is not 12345, it has been changed by someone and they need to tell you what it is. There is a master unlock code generator out there somewhere that gives you the master security code based on the IMEI number of the phone. This doesn't work for all Nokia phones though.

It's been a long time since I've owned a Nokia but I seem to remember that there is a security option to ask for the security code whenever a different sim card is inserted in the phone.You can try using the mastercode generator here,I don't know if it supports your model but it will cost nothing to try,just use the mastercode in place of the security code.If that fails I suppose the only other option is to contact the previous owner and ask him for the code.

Thanks for all the advice guys. Previous owner has no clue what it is and thankfully will take it back. Oh well that's life no?

Another popular security code is the last four digits of the telephone number ... ATT sent me an e-mail with my phone number ... the phone arrived without a hint of a telephone number ... and the last four digits of my phone number unlocked it.

After you've tried three or four codes .... the phone will now need the PUK or PUK2 code, which the carrier has.

Another possibility is a cell phone repair shop who can reset everything with hardware.
