I have an old Nokia that i found and it works. But there is a security code that I forgot from along time ago. Is there like a code that works or somesort of method that resets the passcode?
The phone is a Nokia and its type is: nsd-1aw

If you can't remember the security code for your old Nokia mobile phone, The best option is to do a master reset to your phone. Doing so would restore your phone to default factory settings. So your security code also will get restored to default "12345" . You can get the free master reset code for a Nokia phone from Unlocking4Free.com . This site provides free master reset codes for certain basic model Nokia phones. I hope you would get a solution for your old Nokia too. Good luck mate.
