The internal modem option requires a SIM card connection. The SIM card slot is located on the left side
panel of the device. Two types of SIM-card-slot mechanical covers are provided for card protection:
Rubber cover that allows the end-user access to the SIM card during operation
Plastic cover that prevents SIM card access from the end-user. Once inserted, after the SIM card
installation it can only be broken (physically) by an external mechanical tool to expose the card.
NOTE:
The GSM / GPRS option is a significant power consumer of the platform. If your solution
requires Portable operation including cellular communication, consider the Enhanced
battery option while specifying your device configuration.
