Use only original nano-SIM cards. Use of incompatible SIM cards may damage the card or the device, and may corrupt data stored on the card.
Use only compatible memory cards approved for use with this device. Incompatible cards may damage both the card and the device and corrupt data stored on the card.
Put a nano-SIM card in slot 1 and either a second SIM or a memory card in slot 2 with the contact areas face down.
Both SIM cards are available at the same time when the device is not being used, but while one SIM card is active, for example, making a call, the other may be unavailable.
Important: Do not remove the memory card when an app is using it. Doing so may damage the memory card and the device and corrupt data stored on the card.
