Using the SIM card slot
The SIM card slot holds one SIM (Subscriber Identity Module) card. A SIM card is a smart
card, about the size of a postage stamp, that stores information about your wireless
account.
You need to use a SIM card only if you are using Mobile Broadband on a GSM/UMTS/HSPA
network. Contact your service provider for details.

below the diagnostic port.
3. Place the SIM card label side down on the battery tray. Ensure that the notch on the SIM
