SIM Application Toolkit (SIM AT) is a smartcard centric method of deploying applications that
applies only to GSM and to SMS and USSD transports. Applications must be distributed on
smartcards. WAP is an Internet centric method of deploying applications that is independent of
the network technology. Applications and content are kept centrally on web servers and downlo-
aded as required. While there is some overlap, WAP is a particularly good choice when deploy-
ing applications that also have an HTML version for desktop use. There is current work on
building interfaces between the two technologies.
For an operator, a company or a Service Provider, SIM AT offers a prowerful way to deploy
applications and services to users, without the need for new or upgraded equipment. All neces-
sary setup and programming is distributed to the users over the air, directly to their phones. In
the Ericsson R320s, a separate menu is available for functions residing on the SIM. These can
include submenus for the user to control the functions, and also functions which allows the
phone to initiate calls, send data, display information to the user.
