14. SIM Application Toolkit (SAT) Commands
This chapter offers a brief reference of commands and responses related to the MC35i's SIM Application Toolkit
(SAT) implementation. Detailed information is available with the document "Remote-SAT User Guide" [5]. Please
contact the Wireless Modules Application Engineering Department at Siemens AG for details.
ETSI specification GSM 11.14 [22] defines SAT in detail.
SAT allows for the execution of applications provided by a Subsciber Identity Module (SIM). Usually SIM cards
are used for storing GSM network provider and user specific data, e.g. phonebook entries and Short Messages
(SMS). However, a SIM card may also hold a SIM Application.
Since the MC35i has SAT functionality it is able to execute the commands issued by applications implemented
on a network provider specific SIM card.
Two groups of commands are used between the ME and the SIM Application:
• Proactive Commands are issued to the MC35i's SAT from the SIM Application, such as "DISPLAY TEXT".
• Envelope Commands are responded to the SIM Application from the MC35i, such as "MENU SELECTION".
