General Guide

USSD (Unstructured Supplementary Service Data) is a Global System for Mobile Communications (GSM) protocol. USSD uses codes made up of the characters that are available on a mobile phone. A USSD message, which can be up to 182 characters long, establishes a real-time communication session between the phone and another device typically, a network or server.
USSD can be used for Wireless Application Protocol (WAP) browsing, mobile money services, prepaid callback service, menu-based information services and location-based content services.
With USSD, users interact directly from their mobile phones by making selections from various menus. During a USSD session, a USSD message creates a real-time connection. This means USSD enables two-way communication of information, as long as the communication line stays open. As such, queries and answers are nearly instantaneous.

How USSD works
Typically, USSD involves a query from a mobile phone user, such as a request for a bank account balance. Once the user sends the request, the USSD gateway forwards it to the user's USSD application, which responds to the request.
The process is then repeated in reverse, i.e., the response goes back to the USSD gateway, which displays the content of that response on the screen of the user's mobile phone. Generally, the responses, which contain a maximum of 182 alphanumeric characters, are sent in a format that's easy to display. The user sends and receives data by dialing a specific short code usually, five numbers.
USSD applications run on the network, not on a user's device. As such, they don't have to be installed on the user's phone, which is an advantage for users with feature phones that have limited storage space. USSD apps are instantly available to every subscriber the moment they're deployed to a network.

This USSD System simplifies the process of acquiring various services from the University without need of users having internet at the time.
Currently, the service is only accessible by Tigo Subscribers whom their numbers are registered in their respective ZUMIS system Accounts.
