Available by almost all SIM vendors
Mobile application developers take advantage of proven and widely implemented technologies such as Cell Broadcast, USSD and DSTK to create mobile services that can reach a potential customer base of one billion subscribers. All the major SIM vendors have implemented SmartTrust Wib. To date over 115 implementations from 25 SIM vendors have been certified.

Tangible benefits
Operators are searching for new applications to promote to their subscribers. Operators that have launched services on SmartàLaCarte™ report revenues up to 5 times more than services only available through SMS and WAP. By introducing applications on an easily accessible menu in the handset, subscribers utilize the services that are convenient and easy to use. No need to get the handset configured, no need to browse for info or for downloading software. Just click and go!
SmartàLaCarte enables a dynamic menu context to be presented on any
GSM handset. The concept uses a card-based, light weight application
environment. It provides the user the simplicity of SMS services, the
possibility to retrieve information as WAP and to utilize GSM functions
like cell positioning. In short, the best of all worlds.
The solution behind
Value proposition to the VAS ecosystem
Make it easy
The menu is in the handset – no need to remember key words, navigate web sites or configure the phone. The subscribers get immediate and always-present access to services without configuration or installation, works from day one and always on-line. The personal menu follows the user when changing handset
Available to all - works on all handsets and SIM cards
It is a turnkey solution for launching value-added services to the entire subscriber base through a standard SIM, independent of handset model. Services are easily and quickly available via handset menus. And because the operator controls the SIM, it’s easy to ensure correct provisioning and that services are available from day one.
Immediate access to new services
Content and applications can be dynamically fetched and executed on the fly. Services can be changed and new services added “on-the-fly”. The payload is optimized for size.
Service usage
After service selection from the menu, the application on the SIM is initiated and sends a request to the application / content provider. The provider returns the information and sends it to the handset through the SmartTrust platform or via another technology such as SMS, USSD, WAP or voice.
"Making services available to any subscriber.
Always. Easily"
The are many opportunities for new income generating applications in
vertical industries. Here are some examples of generic services suited for
DSTK. What’s your idea?

What’s your idea?
There are numerous untapped possibilities for new Value Added Services, you have probably some great ideas that can be realized successfully on DSTK technology.
Mobile Banking
Gives the users a bank in their pocket. Ability to bank securely on the move and to transfer funds right when its needed.
Update Services
Sometimes the results is what counts. Let the subscriber keep abreast of information of his favorite interest.
Self Service Customer Care

Voting
The SIM technology can be used for secure personal voting. For example, for official ballots, competitions running on TV and Radio or customer preference surveys.
When designing or adopting a service to DSTK, it is useful to match the
subscribers’ needs with the capability of the technology. In the model
below you can depict these needs, and what can be realized with a
mobile phone using DSTK. If your services fit within the technical
boundaries you will succeed with the application!
Evaluation of dynamic SIM menus
Compare DSTK’s features with the users’ needs
Variable 1 – Need to remember
Does the user have to remember codes, numbers etc in order to perform the service (for example, USSD codes like *123# or short codes in SMS like ADTCKZA. A SIM menu based solution is then preferable as it will display the option in readable text, for instance: “Adult Ticket for zone A”
Variable 2 – Need quick transaction
Does the user need a quick transaction or will the user prefer to spend time writing text or browsing a webpage? A SIM menu solution is made for speedy transactions: “get me that now”.
Variable 3 – Need mobility
Does the user need mobility or can they solve the task in another way? A SIM menu based solution is simpler for accessing a mobile service faster and better: “I did it with my mobile”
Variable 4 – Need of information
Does the user need a lot of information or can the task be resolved with just 2-3 interactions? A SIM menu based solution is made for a lower number of interactions with concise information; WAP and WWW can better cater for demand of rich media.
Variable 5 – Need positioning
Does the user need a quick rough positioning in order to better solve the scope of his query? A SIM menu based solution with automatic positioning can enrich and facilitate the transaction, for example purchasing a ticket or updating of status in communities.
When a subscriber selects a menu entry on the handset, Wib is invoked
to execute the service chosen by the subscriber. The service can be
locally executed on the SIM to perform some task or asked to fetch
additional content from the server side of the application. Then the
SmartàLaCarte Universal Gateway™ will request WML instructions using
the https protocol from the application server and transfer the answers to
the WIB on the SIM card converted into byte-code, also known as
“wiblets”.
The execution of a WIB application
The wiblets are sent and interpreted
by the WIB on the SIM card that then
orders the execution on DSTK
commands on the phone.
SmartàLaCarte enables dynamic
exchange of data between a content
or application provider and the
mobile phone.
The Wib concept enables your application to be utilized dynamically by the subscriber. It combines the features of dynamic information over the internet, core GSM network services and handset execution, making it optimal for applications used frequently by the subscriber.
SmartTrust has designed a development tool that enables the developer
to write code and test its functionality on the spot. The WAC tool
simulates the complete mobile environment including SmartTrust DP™,
the GSM network, the mobile terminal and the SIM card with SmartTrust
Wib. It also enables you to verify your WML code. Download it today, its
free!
Wireless Application Creator - WAC
Pushes wiblets for
one time execution
to the phone.
Key features of the WAC:
• Edit your own WIG WML applications in an editor included in the tool
• Verify them in a Wib and phone simulator (the WIB Phone) included in the tool
• Fetch and simulate live WML applications directly from URL addresses on a web server
• Push WML applications to an existing SmartàLaCarte system for delivery and test on a real phone with Wib.
