USSD (Unstructured Supplementary Service Data) is a communication protocol used by mobile telephones to communicate with the mobile network operator's computers. It allows users to access various services such as checking account balances, topping up credit, and accessing other information or services. USSD messages are sent via the signaling channel, which means they are transmitted instantly and do not require a dedicated data connection.
USSD is widely used in many parts of the world, particularly in developing countries where access to data networks may be limited. It is a simple and reliable way for users to access various services and information on their mobile devices.
