Go omni-channel across all brands while reducing TTM and TCO

A new legacy on top of an old one

Sprint, which has since merged with T-Mobile US, had an ambitious wish-list: to go omni-channel across all brands, improve time to market for promotional offers, empower business users to define offers, and have always-on scalability. 

The solution we provided was on top of their legacy billing system. It’s a platform designed to support continuous innovation and enable a digital omni-channel customer experience. It comprised our DigitalONE suite (commerce, order management and care) as well as CatalogONE and Microservices360 foundation. 

Unified, simplified and working – in just weeks

We used TM Forum’s open APIs and a unique co-development model across the lifecycle of this complex, end-to-end modernization project – applying microservices development practices and a seamless continuous integration and continuous delivery (CI/CD) process.

The result? The business moved from a heavily siloed environment to a unified, simplified cloud-native architecture that delivered new functionality in weeks rather than months.


  • Common UI across all channels
  • A single catalog derived from over 20 catalogs
  • Time to market down by 50%
