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
requests the G24-L to pass local information to the SIM, for
example, the mobile country and network codes (MCC + MNC)
of the network on which the user is registered.
Send DTMF Defined as part of the proactive SIM service, this command
requests the G24-L to send DTMF tone(s) during an established
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.
Launch Browser Defined as part of the proactive SIM service, this command

interpret the content corresponding to a URL. Refer to “Launch
Browser”, page 3-264.
