For Nokia - X and C Series
The Nokia mobile phone can be used for multimedia and other storage functions. The handset saves all items, such as music and pictures, to a memory card instead of the built-in storage. Memory cards such as a microSD can be locked to prevent unwanted access to your private items. The card cannot be used in any other phone. If you purchased a used card or forgot your password, you can unlock the memory card.
