The Unstructured Supplementary Service Data (USSD) allows cost-effective, interactive communication between subscribers and applications across a UMTS/GSM network. Its functionalities make it ideal for information queries like available balance, content downloading and any information services.

The LeibICT USSD Gateway is a carrier-grade system to integrate with many USSD applications and at the same time minimizes cost and maintenance of multiple information systems. Its HTTP, XML/TCP/IP and provided Java and C++ client libraries reduce the time of development and lets you concentrate on the service itself, not on the protocols.
The AES-256bit/RSA-4096bit channel encryption, a unique feature, makes the USSD Gateways secure and ideal for banking and billing applications.
USSD is primary used on real-time and instant messaging type phone services because there is no store-and-forward of messages typical of the short message services (SMS). The response time for a USSD request is measured between 100 and 200ms compared to the 5-10 seconds of SMS.
