SIM application toolkit
The SIM Application Toolkit (SIM AT) is a smart
card-centric method of deploying programs that
applies 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 network
technology. Programs and content are kept cen-
trally on web servers and downloaded as required.
While there is some overlap, WAP is a particularly
good choice while deploying programs that also
have an HTML version for desktop 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 deploy programs
and services to users, without the need for new or
upgraded equipment. All necessary setup and pro-
gramming is distributed to users over the air,
directly to their phones. In the J200, a separate
menu is available for functions residing on the SIM
card. These can include submenus for controlling
functions, and also functions that allow the phone
to initiate calls, send data, and display information
to the user.

that enables secure distribution, promotion and

The J200 includes implementation of EMS ODI

content).
While downloading content via WAP, the J200
includes support for OMA (Open Mobile Alliance)
defined DRM solution forward lock, meaning that
content is packaged in a DRM package and
delivered to the device. The support of forward lock
means that it is not possible to forward the
downloaded content to any other device. Forward
lock is useful for all types of content that the
provider wants to charge for.

Write protection and copyright
Operators may choose to have some of the cus-
tomized content in the phone write protected, so
that it cannot be deleted from the phone.

There is also the option to copyright customized
content in the phone, such as pictures and sounds.
A copyrighted picture or sound cannot be redistrib-
uted via IR or EMS, for example, and in the user
interface, the “Send” option for the item is greyed
out.
