USSD service can be used to allow MTN Eswatini mobile users to access enterprise services (applications) like banking services, service enquiry and more, from any type of phone. The users interact with the content provider (CP) enterprise in real time.
The CP is allocated a unique 3 or 4 digit USSD code e.g. *001# which the users would dial to access that particular CP’s content or service.
