Delivery partner to Teraflow. This was not a direct contract with Cell C.

Checking a balance or topping up may look simple in an app. Each journey depends on the wider product, its data, service rules, and integrations working together. The engineering challenge is to make those tasks clear for customers while respecting the behaviour of the systems behind them.

Abantu led frontend architecture and delivery as part of the Teraflow delivery partnership on the Cell C programme, from March 2024. Our work focused on the customer-facing mobile experience and the engineering needed to deliver it within a larger telecommunications environment.

The published app supports balance checks, recharges and top-ups, linked numbers, and account and settings controls. It is available on iOS and Android.

In a complex customer product, responsible engineering starts with understanding what the system does, what customers depend on, and how a change can affect related journeys. That context makes it possible to improve the experience without treating the app as an isolated piece of code.

Let's talk about the business context and the engineering challenge.
