Note: All GSM service providers may not support transparent mode. In those
cases, the Novatel Wireless M2M Enabler IIIG module can be configured to switch
automatically to Non-Transparent mode. This capability depends on the settings
in the AT+CBST command.
SMS: Short Message Services
l
Short Message Services (SMS) is a feature-rich GSM service. The Novatel Wireless M2M
Enabler IIIG module can perform the following tasks:
l
Sending and receiving binary messages of up to 160 characters (7-bit characters)
l
Sending and receiving text messages of up to 140 bytes (8-bit data)
l
Submitting a SMS Protocol Data Unit (PDU) to a SMSC (Short Message Service Center)
and storing a copy of the PDU until either a report arrives from the network or a timer
expires
l
Receiving a SMS PDU from a SMSC
l
Returning a delivery report to the network for a previously received message
l
Receiving a report from the network
l
Notifying the network when the module has sufficient memory capacity available to
receive one or more SMS messages (after the module had previously rejected a
message because its memory capacity was exceeded)
Provisioning The SIM
The SIM can support optional features or services. Most operators typically configure the SIM
to send/receive voice calls and to receive SMS; however, some may require an additional tariff
to enable the SIM to send SMS. The transmission of circuit switched and GPRS data are also
additional services that may be required to allow the service:
l
Mobile-originated (MO): allows making a service request (such as, making a call or
sending an SMS)
l
Mobile-terminated (MT): allows receiving a service request (such as, receiving a phone
call or an SMS)
It is imperative for the Novatel Wireless M2M Enabler IIIG module that the SIM be configured
for the optional services that are required for the application.
GSM Services Supported By The Novatel Wireless
M2M Enabler IIIG Module
The Novatel Wireless M2M Enabler IIIG module supports four GSM services (modes of
operation) that must be enabled by the operator:
