MobilisUSSD facilitates the use of Unstructured Supplementary Service Data on GSM phones. Popular applications of MobilisUSSD are for low cost real-time or instant messaging phone services, balance checking, and the delivery of 3rd Party promotions and information.
Because the USSD Gateway provides no store-and-forward capability an SMSC is not required for the delivery of service. Additionally, response times for interactive MobilisUSSD-based services are generally shorter than those used through SMS.
