It supports four GSM bands: GSM850, GSM900, DCS1800 and PCS1900.
Parameters can be set using the dedicated configuration software or by sending AT commands through the serial port.
The device draws 69 mA in standby mode.
GPS data can be sent periodically by enabling the heartbeat packet or retrieved on demand with the AT+GPS command.
