USSD

Short for Unstructured Supplementary Service Data, (USSD) is a technology unique to GSM that enables session-based text-
messaging as opposed to SMS, which is store-and-send text-messaging. Turnaround response times for interactive applications
are generally shorter for USSD than SMS. USSD is not currently available on all carrier networks.
USSD communicates with a USSD application portal, a news portal or a chat session with a co-worker.
