Type: The NM-GPRS/GSM module supports 3 types of operation modes. The choices are GSM,
GPRS, and SMS.
SIM PIN: This is a pin code that locks the SIM card until you enter the correct code. This protects
your account. The default code is set by the Service Provider.Note that a cell phone must be used
to change the PIN.
Selecting the Radio Band: Although GSM-900 and GSM-1800 are used in most parts of the
world, operators in United States, Canada, and many other countries in the Americas use GMS-850
or GSM-1900. A quad-band industrial cellular modem such as the NM-GPRS/GSM module makes
it relatively easy to prepare the product for shipment to different parts of the world. The
GSM/GPRS band of NM-GPRS/GSM module is configured to 900/1800 MHz by default.
Additional settings for each of the three modes are described in the following subsections.
GSM Operation Mode
PPP Mode: PPP provides standard PPP dial-out service.
PPPD Mode: PPPD (PPP Daemon) is used for dial-in services, since it provides PPP services only
when receiving a request from a remote PC.
