state of the sending of the SET UP
MENU proactive command (37),
refer to AT#STIA? command
A typical SAT/USAT session, running on AT interface, starts when the user
receives the #STN: 37 URC. The unsolicited result code must be previously
enabled by the #STIA command. The #STN: 37 notifies the user that the
main menu of the SIM/USIM Application has been sent to TA, and TA has
stored the just received menu. Later, at any time, you can type in
the AT#STGI=37 command to display the main menu of the SIM/USIM
Application on TE.
Upon receiving the #STGI response, you must enter the #STSR command to
confirm the execution of the proactive command and provide any required
user response. In this case, you must enter the AT#STSR=37,0,x command
to select the x item of the SIM/USIM Application menu.
The #STN: 237 URC indicates that the main menu of the SIM/USIM
Application has been removed from TA, and it is no longer available. In this
case, AT#STGI=37 command returns ERROR message.
