The average Nokia 6500 owner may not be aware of the phone's hidden codes, which aren't readily available to the end user. Much like with other Nokia phones and also other phone brands, these hidden codes reveal certain information about the phone that can come in handy.
IMEI
The International Mobile Equipment Identity (IMEI) is a number uniquely designated to all mobile phones, including the Nokia 6500, for identification purposes. From the main of the Nokia 6500 phone, tap *#06# for the phone to display the IMEI number. You can save this number to furnish to your network operator for blacklisting purposes should your phone be stolen.
Default Unlock Code
Should you forget your security unlock code on your handset, you can enter "12345" as the pass code to unlock the Nokia 6500 handset. Since this code is a universal master pass code, remember to change it once you gain access to your phone.
Firmware Version
In order to update the software of your Nokia 6500, you have to know the current version of your phone to check whether it can be updated to newer firmware. Dial *#0000# at the main screen to view the handset's version and date.
Warranty Information
Dial *#92702689# from the main screen of the Nokia 6500 to display the Life Timer, Date of Manufacture and date of repair (if any). This information is essentially important, especially if you intend to buy a used Nokia 6500 from a third party.
