What Are USSD Codes?
USSD, or Unstructured Supplementary Service Data, is a communication protocol used by cellular telephones to communicate with the service provider’s computers. It allows users to interact directly with the computers of the cellular network operator and facilitates a range of network services.
- USSD codes are composed of numbers and symbols, for example, *123#, which are used to send queries to the mobile network.
- Unlike SMS, USSD provides a much faster way to communicate since it establishes a real-time connection during the session.

How Do USSD Codes Work?
USSD codes function as a session-based service, enabling users to keep a connection open with the operator’s server for a limited time. Here’s a breakdown of how they operate:
- The user initiates a USSD session by entering a defined code on their mobile device.
- This triggers a session request to the service provider’s network.
- During the session, the server can send a text-notifications or menus that the user interacts with using numerical inputs.
- The session ends once the user disconnects, or after a predefined period of inactivity.
USSD has a distinctive safety mechanism, ensuring any data sent during a session remains secure due to its session-based nature.
