As a mobile network operator, you have invested heavily in USSD applications that support subscriber self-service, mobile money, prepaid services, loyalty programmes, service activations, account enquiries, CRM integrations, and countless other business processes.
These applications represent years of development, testing, and operational refinement. They contain proven business logic that you want to preserve, yet their capabilities remain largely locked behind interactive USSD sessions.
At the same time, customer expectations are changing. Mobile apps, web apps, WhatsApp, partner systems, AI services, chatbots, and enterprise applications require standards-based API access rather than interactive USSD sessions. Simply redeveloping existing USSD services for each new channel would be costly, time-consuming, and a big headache to maintain.
The challenge, therefore, is not replacing your mature USSD applications or duplicating functionality that already exists. It is finding a way to preserve your existing investment while making these proven services available to modern digital channels for customers on newer network technologies.
Ziwa USSD gives you modern self-care channels by automatically exposing your existing USSD services through APIs. Your proven business logic remains intact, ensuring that the same services, rules, and processes are applied consistently across all your digital channels.
Ziwa USSD lets you extend the value of your existing USSD investment without the cost, time, and risk of redeveloping established services. It does not replace your mature USSD applications or duplicate functionality that already exists. Instead, it makes their proven capabilities available to today's digital channels.
Ziwa USSD achieves this by connecting to your existing USSD services and interacting with them just as a customer would, navigating menus, supplying inputs, and collecting responses. Your existing applications do not need to be changed, redeveloped, or even touched.
A single Ziwa USSD integration point is all that is required. As shown in the figure below, every USSD application already deployed behind your gateway can be accessed through this common integration point. This means you can make multiple existing USSD services available to digital channels without creating separate integrations for each application.
And to get your first digital channel up and running quickly, Ziwa provides a ready-made Web-Based Self-Care UI. It automatically converts your existing USSD services into a modern web experience, complete with customisable menus, favourites, search, and advertising space. It’s the fastest, simplest way to bring your USSD services into the digital era.
As part of the wider Ziwa platform, Ziwa USSD transforms, normalises, and structures the data it collects before exposing it through clean, standards-based REST OpenAPI interfaces.
These APIs can then be consumed by a wide range of modern applications and channels, including:
The result: you keep the services you already invested in, your business logic remains untouched, and you bring new digital services to market in a fraction of the time a rebuild would take.
Digital transformation doesn't always mean replacing what works. Ziwa USSD unlocks the value already built into your network.
