Unlock a security code

SOURCE: Security code on my Nokia 1600

I need the IMEI (International Mobile Equipment Identity) number. Type this code in your phone to get it: *#06# you can also find it beneath the battery.
Then I’ll give you the Master code to reset your Security code.

WELL IT SHOULD BE 12345 BUT IF THAT IS NOT IT YOU WILL HAVE TO PROVIDE US WITH YOUR IMEI# YOU CAN GET THIS BY PRESSING *#06#

You cant unlock these phones by code, unless you buy the network code directly from your network... To reset the security code you need to connect the phone to professional equipment like Jaf, etc...

These are BB5 handsets...

The default code is 12345. That is if you did not change and forgot it. If forgotten then re-installing the firmware is the only answer. Go to the nearest Nokia Care.
