What is USSD?

Unstructured Supplementary Service Data (USSD) is a protocol used by GSM cellular telephones to communicate with the service provider's computers.

Unlike SMS, USSD creates a real-time connection during a USSD session. The connection remains open, allowing a two-way exchange of a sequence of data. This makes USSD more responsive than services that use SMS.

Common Use Cases:

  • Mobile Banking & Payments
  • Balance Inquiries & Airtime Top-ups
  • Surveys & Data Collection
  • Two-Factor Authentication (2FA)
  • Customer Self-Service Menus
