USSD Full Form: USSD stands for Unstructured Supplementary Service Data. QuickCodes and feature codes are alternate names for USSD. It is a networking protocol that GSM (Global System for Mobile) phones use to send contact or text messages from a cell phone to an application hosted by the mobile operator. In a nutshell, it is a system that allows GSM-based cellular phones to communicate with the network operator’s equipment.
USSD is a session-based specification that establishes a real-time session between a mobile device and a network operator’s device. The only difference between it and SMS is that, unlike SMS, USSD transactions take place only during the session between the parties involved. USSD is a bidirectional knowledge exchange that takes place as long as the link is open.
