The Problem

International consumers relied on scratch cards and memorized PINs. They wanted a modern app that handled account balances, promotions, and auto-dialing with reliable voice quality.

The Challenge

We had to integrate carrier-grade VoIP gateways, provide real-time rate updates, and deliver a frictionless dialing experience that works across varied network conditions.

Support secure, rapid top-ups and track balances in real time.
Provide carriers with insight into usage patterns and promotion performance.
