USSD (Unstructured Supplementary Service Data) codes are a type of communication protocol used by GSM cellular telephones to communicate with the service provider's computers. They allow users to access various services and features directly from their mobile devices by entering a specific combination of digits. These codes are usually preceded by a * and followed by a #, for example, *123#.
