Important: Do not use a mini-UICC SIM card, also known as a micro-SIM card, a
micro-SIM card with an adapter, or a SIM card that has a mini-UICC cutout (see figure)
in this device. A micro SIM card is smaller than the standard SIM card. This device does
not support the use of micro-SIM cards and use of incompatible SIM cards may damage
the card or the device, and may corrupt data stored on the card.
A SIM card may be already inserted in the device. If not, do the following:
1 Open the cover of the SIM card slot.
2 Insert a SIM card in the SIM card slot. Make sure the contact area on the card is facing
up. Push the card in.
