What is ussd? Unstructured Supplementary Service Data (Unstructured Supplementary Service Data) is a communication protocol used by GSM mobile phones for mobile phones. Communication with the mobile operator's computers is used. USSD can be used to browse WAP, payment services (banking portals), mobile payments, location-based content services, menu-based information services, and as part of a network configuration. What is the power of ussd? USSD messages have a maximum of 182 alphabetical characters. Unlike SMS messages, USSD messages create a real-time connection during user dialing and as long as the user is using ussd, this connection is still open (as long as the user is connected to ussd). And allows for two-way data exchange. This makes USSD more responsive to services that use SMS. What is the superior advantage of ussd? Another feature that no service other than ussd can find is that the USSD codes do not require internet and mobile charging, and the ussd runs on all mobile devices and does not require a special operating system or software installation. This unique advantage makes it possible for anyone with any mobile phone, with any operating system, to access and view and order your products and services at high speed.
