USSD (Unstructured Supplementary Service Data) is a user-friendly and highly scalable mobile service that leverages the underlying GSM network. Users can access various services by inputting a short code on their mobile device, initiating a text-based interaction. This simplicity and flexibility allow operators to customize services to specific user needs.
