Unstructured Supplementary Service Data – USSD

What is USSD?

USSD stands for Unstructured Supplementary Service Data – a GSM service that enables a real-time connection between a phone and a software application, typically in the mobile operator’s network. 

Unlike SMS, USSD is a session-based protocol which allows real-time interaction between the software and the end user. 

Operators use USSD to allow end users to check their balance, re-provision their phone plan, check settings, and more. For instance, end-users can get their IMEI codes by dialing *#06#.  

What are the benefits of USSD? 

With USSD, end users don’t need to install any extra applications to access the services – it all happens through the network!  

Plus, USSD is very cost-effective and works smoothly in every corner of the globe.
