Topmark USSD


USSD allows for interactive, menu driven, 2-way communication between subscribers and applications and offers a quick and direct way of transacting with clients.


USSD works over mobile channels as sessions, or “conversations”. The user communicates with an application by navigating through a menu based structure. Customised menus and services can be easily created using Topmark’s proprietary USSD builder. USSD technology requires no software installation on the handset or SIM card. A session can be initiated by the mobile user or the back-end system, using an SMS, voice call, predefined web trigger or a USSD short code.

This solution has been developed from Topmark’s years of engineering experience in the telecoms market. It is stable and secure and is able to meet every kind of business requirement. Topmark USSD is seamlessly integrated into any existing platform, regardless of industry.
