Ok. here’s a list of product codes for the Asian market:
What is a Nokia product code?
It’s a 7-digit code that identifies the firmware installed in your Nokia phone. It also defines the features and languages installed in it. Product codes are region dependent. Where you purchased your Nokia phone corresponds to the code it has.
Some Nokia enthusiasts will change the product code of their Nokia phones to alter their phone’s features. The most common reason is to “de-brand” a Phone company-issued phone, most of which have limited features compared to the retail ones.
Where can I find my Nokia product code?
It is usually printed on the sticker at the back of your phone when you take out its battery. Look for a 7-digit code just below your Nokia’s IMEI (International Mobile Equipment Identity).
How do you change the product code?
The most common program to change the product code is the Nemesis Service Suite, or NSS. The latest version of NSS has no problem detecting the E71. There are also some programs that can change the product code, diagnose and and even upgrade or downgrade the firmware of your Nokia phone. But these programs costs a lot and needs proprietary hardware to work with.
What happens if I change my product code?
You will lose your warranty. 😛
