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 and the bevelled corner is facing toward the device. Push the card in.
