SIM application
toolkit
The SIM Application Toolkit (SIM AT) is a smart
card-centric method of deploying programs that
apply only to GSM and to SMS and USSD
transports. Programs must be distributed on
smart cards. WAP is an Internet-centric method
of deploying programs that is independent of
network technology. Programs and content are
kept centrally on web servers and downloaded
as required. While there is some overlap, WAP is
a particularly good choice when deploying
SIM AT services supported by the T68i

programs that also have an HTML version for
desktop use. Work is currently under way on
building interfaces between the two
technologies.
For an operator, a company or service provider,
SIM AT offers a powerful way to deploy
programs and services to users, without the
need for new or upgraded equipment. All
necessary setup and programming is distributed
to users over the air, directly to their phones. In
the T68i, a separate menu is available for
functions residing on the SIM card. These can
include submenus for controlling functions, and
also functions which allow the phone to initiate
calls, send data, and display information to the
user.
