9. SIM Operation 

 

 

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: 
 

• 

Mobile-originated (MO): allows making a service request (such as, making a call or sending an 
SMS) 

 

• 

Mobile-terminated (MT): allows receiving a service request (such as, receiving a phone call or an 
SMS) 

 
It is imperative for the Enfora Enabler II-G A-GPS module that the SIM be configured for the optional 
services that     are required for the application. 

 

 

The Enfora Enabler II-G A-GPS module supports four GSM services (modes of operation) that must 
be enabled by the operator: 
 

• 

Voice calls (MO and MT): requires a telephone number 

 

• 

SMS (MO and MT): uses the telephone number for Voice 

 

• 

Circuit-switched data calls (MO and MT): requires a telephone number 

 

• 

The GSM SIM can have multiple telephone numbers. 

 
 

 

The Enfora Enabler II-G A-GPS module supports the following GPRS (modes of operation) that must 
be enabled by the operator: 
 

• 

GPRS Packet Connectivity (MO and MT) with Both Dynamic and Static IP option 

 

• 

GPRS SMS (MO and MT): uses the IP (Dynamic or Static) set by the operator 

 

• 

Multiple APN Setting
