As networks evolve to LTE and 5G, long-established USSD services—such as balance checks, top-ups, prepaid credit requests, or self-care menus—must remain available in an all-IP environment. Via our CreaLog OSS Gateway, USSI delivers this continuity by bridging IMS infrastructures with existing service platforms. It converts USSD requests sent over SIP into the appropriate signaling for prepaid systems and call completion applications, ensuring that customers can still access familiar interactive services. By preserving these proven user journeys while integrating them into modern VoLTE and 5G networks, operators secure both service reliability and customer satisfaction.
