Unstructured Supplementary Service Data (USSD) is service offered by network providers to get information about subscriber account, mobile-money services, menu-based information services etc. Subscriber sends a short code(ex. #225#, *43#)\u00a0 from the device to request for specific service on the network. As an example, in T-Mobile network in U.S, you can send #225# from your phone to check account balance and last payment. The short codes different in each network.<\/p>\n

AT+CUSD command is used to send USSD codes to network. The short code and encoding format are passed as command parameters. Network response is usually received within few seconds.<\/p>\n

AT Command Tester tool provides an east interface to test USSD messages. User can enter the USSD code and look at the AT command request and response on the command window. The network response is parsed and displayed as well.<\/p>\n
