This mechanism allows SIM applications to generate powerful menu-driven sequences on the customer
application and to use services available in the network.
The commands used for this operation are:
+STIN (SIM Toolkit Indication),
+STGI (SIM Toolkit Get Information),
+STGR (SIM Toolkit Give Response).
Data Download to SIM
Data downloading to the SIM (SMS, phonebook…)allows data or programs (Java applets)received by
SMS or by Cell Broadcast to be transferred directly to the SIM Application.
This feature does not need any AT command. It is transparent to the customer application.
Menu Selection
A set of menu items is supplied by the SIM Application ToolKit. The menu selection command can then be
used to signal to the SIM Application which menu item is selected.
The commands used for this operation are +STIN, +STGI and +STGR.
Call control by SIM
The call control mechanism allows the SIM to check all dialed numbers,
supplementary service control strings and USSD strings before connecting to
the network. This gives the SIM the ability to allow, bar or modify the string
before the operation starts.
The commands used for this operation are :
+STCR (SIM Toolkit Control Response),
+STGR (SIM Toolkit Give Response).
