Your phone has an expansion slot compatible with microSD memory cards, which are primarily used to back up or transfer files and data.
Note: Use only compatible memory cards with your phone. Using incompatible memory cards, such as Secure Digital (SD) cards, may damage the card, as well as the phone, and data stored on the card.
Inserting the microSD memory card
Push the microSD memory card into the slot with the label side face down until it clicks into place. The card is secure when it is not protruding from the phone
