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 trans-
ports. Programs must be distributed on smart-
cards. WAP is an Internet-centric method of
deploying programs that is independent of net-
work 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 pro-
grams that also have an HTML version for desk-
top use. Work is currently underway on building
interfaces between the two technologies.
For an operator, a company or service provider,
SIM AT offers a powerful way to develop pro-
grams and services to users, without the need for
new or upgraded equipment. All necessary setup
and programming is distributed to the users over
the air, directly to their phones. In the T600/T602,
a separate menu is available, and there are also
functions which allow the phone to initiate calls,
send data and display information for the user.
