Project Details

  • The client was seeking a one-stop shop for all telecommunications needs; offering a wide range of products and services for individuals, enterprises, and homes through an application.  The client further wanted a platform with its own billing solution and real-time customer insights.  


  • The client did not have any consumer-facing digital applications.  
  • Additionally, Emtel did not have its billing solution, instead, the existing system was routed through the Ericsson payment and billing module.  
  • The key challenge with this system was that the consumer did not have an access to their real-time consumption of services which led to user dissatisfaction.  
  • Emtel was not able to cross-sell or upsell its services as there was no real-time visibility of customers’ usage.  
  • The other key challenge was to comprehend the backend engine built by Ericsson and integrate it with the proposed application. 

Our Approach

  • Big Oh assessed the entire architecture and created Restful APIs.  
  • We created a middleware written in LARAVEL that could convert data from SOAP to JSON and vice versa so that the systems (Ericsson and Emtel) could seamlessly talk to each other. 
  • Additionally, we built a consumer-facing digital application (Android and IOS Native)  
  • Big Oh custom-created Content Management System (CMS) for Usage and Retention/ Marketing so that Emtel can create on-the-fly offers for its consumers. 
  • A store locator solution was developed to map nearby stores for their consumers. 
  • We also developed a consumer-facing in-app wallet and self-care portal for the client. 


  • With Big Oh’s solution, there was a direct impact on the business growth- sales increased by multiple folds.  
  • The application facilitated greater customer satisfaction which further led to higher customer retention.  
  • Real-time offer management led to higher average revenue per user (ARPU).  
  • Accurate billing and usage details led to a reduced number of customer care calls which in turn led to higher cost savings. 
  • The number of features and flexibility with the plans led to more customer acquisition.
