How a Leading Telecom Provider Achieved Payment Gateway Transformation with Hexaware

Client

A Global Telecommunications Provider

The client is a multinational telecommunications provider operating across multiple international markets with millions of mobile subscribers. The organization delivers mobile connectivity and digital services across diverse regional operations and manages large-scale payment transactions across its customer ecosystem.

Challenge

Fragmented Payment Systems Limited Regional Scalability

The client relied on multiple independent payment solutions with limited connectivity across regions. As payment operations expanded, the fragmented environment created operational complexity and limited centralized visibility into customer payment data.

The organization needed to:

• Unify multiple payment systems into a centralized platform
• Improve visibility into customer payment activity
• Scale payment operations across 15+ regions
• Support multiple payment methods including credit cards and debit cards
• Simplify onboarding of new payment processors
• Improve operational efficiency during peak transaction periods

The client also needed a scalable payment gateway solution capable of supporting regional growth without operational disruption.
