Chapter 3: AT Commands Reference
April 15, 2008 G24-L AT Commands Reference Manual 3-247
•In the first step, the customer application informs the G24-L module that it wants all features
to be supported. This operation is performed using the AT+MTKE (Motorola ToolKit
Enable) command, which allows activating or deactivating the SIM Toolkit functionality.
•In the second step, an unsolicited result +MTKP (Motorola ToolKit Proactive) is sent by the
G24-L in order to indicate the customer application, command type the SIM Application
Toolkit is running on the SIM card, and the relevant information.
•In the third step, the customer application uses the AT+MTKP command to respond to the
SIM ToolKit command, given by +MTKP.
STK Mechanisms
The mechanisms defined for the STK (Table 3-162) are dependent upon the relevant commands
and protocols found in GSM 11.11.
+MTKR, Profile Download
This command displays the profile that is downloaded from the G24-L to the SIM during the SIM
initialization process. This profile includes the facilities relevant to the STK that are supported by
the G24-L,enabling the SIM to limit its instruction range to those STK features the G24-L
supports. (Refer to “Profile Structure”, page 3-248) Without a profile, the SIM assumes that the
G24-L does not support the STK.
Table 3-162:STK Mechanisms
Mechanism Description
Profile Download Enables the G24-L to tell the SIM what its capabilities are. (The
G24-L is aware of the SIM’s capabilities via the SIM Service
Table and EFPHASE.) Refer to “+MTKR, Profile Download”,
page 3-247
Provide Local Information Defined as part of the proactive SIM service, this command

call. Refer to “Send DTMF”, page 3-263.
Set Up Idle Mode Text Defined as part of the proactive SIM G24-L,this command
supplies a text string to be used by the ME as stand-by mode text.
