Set up call
If the user is on a call when the “Set up call, putting
all other calls on hold” command is sent, the user
will see the text, “Let SIM card setup call”. The user
can press OK for the current call to be put on hold
and the new call to be set up.
If the user is on a call when the “Set up call,
disconnecting all other calls” command is sent, the
user will see the text, “Let SIM card set call.” The
user can press OK for the current call to be
disconnected and the new call to be set up.
Set up menu
Incorporates a SIM Application Toolkit menu item
into the ME’s main menu structure.
If an Alpha Identifier is supplied in the Set Up Menu
command, this is used as the SIM AT entry in the
ME’s main menu. If no alpha identifier is supplied
and several items are found in the menu, a default
title is used. If the SIM AT Menu Item is selected by
pressing Select, all the items sent in the Set Up
Menu command are available for selection, in the
same way as the Select Item command.
