What is the code of a Nokia mobile phone:
The Nokia mobile phone code represents the identity of this mobile phone. Because even mobile phones of the same model are sold through different channels or telecom carriers in the same region, nokia has set a code attribute to further differentiate mobile phones of different channels (or even colors. Basically, all configurations of mobile phones with the same code value are identical (even including the body color ).
Mobile phones with the same firmware (type identifier) also have different code values due to different selling countries, channels (such as whether a custom Telecom machine is used), and body colors. These code values can be changed as needed through software.
