CINCINNATI & SINGAPORE--(BUSINESS WIRE)--June 12, 2002

Convergys Corporation (NYSE:CVG), the global leader in integrated billing, employee care, and customer care services, today announced that Indonesia's largest mobile services provider, PT Telekomunikasi Selular (Telkomsel), has implemented Convergys' Geneva(TM) software to rate and bill its GSM and upcoming GPRS services. Global solutions company Logica (LOG.L) performed the systems integration.

The project to migrate Telkomsel's legacy billing system to a sophisticated new convergent billing system was completed in approximately six months and is part of Telkomsel's overall efforts to position itself as a leading provider of next-generation telecommunications services. The new billing and rating system will allow Telkomsel to enhance its portfolio of service offerings by providing new value-added services for its subscribers, including mobile-commerce in the near future.

Mulia Tambunan, President Director of Telkomsel, commented that Telkomsel had chosen Convergys' Geneva because it was flexible enough to bill for a wide range of different services and could also meet future scalability and performance requirements. "Geneva is also extremely user-friendly and its fast implementation schedule allowed us to launch our new services very quickly."

Convergys' Geneva software replaced Telkomsel's existing billing system and is being integrated with third-party mediation software, Oracle Financials, and other in-house applications using BEA System connectors. The Indonesian operator is using Geneva's full mobile functionality including its TAP3 module for global roaming.

Telkomsel is one of the region's fastest growing mobile services operator and currently has nearly 4 million subscribers, about half of the total cellular market in Indonesia. The operator expects to hit 5 million subscribers by the end of the year. Indonesia's population is the world's fourth largest at more than 200 million. Although current cellular penetration is estimated to be just under 3 percent, this figure is expected to climb rapidly as the Indonesian mobile phone market registered an extremely high growth rate of 78 percent last year. Telkomsel has also recently embarked on a major network expansion program to enhance its cellular infrastructure and expand its coverage to cater to its booming growth in subscribers.

Steven Szeto, Vice President and General Manager of Convergys Asia Pacific, said, "Telkomsel is targeting 7 million users by 2003, and it also has its eye on expanding its portfolio for 2.5G and 3G services, so it was important for their billing platform to be able to support its aggressive growth plans. We are pleased that Telkomsel has chosen Convergys' Geneva as its billing platform for all future services."

Geneva is a real-time, transaction-based, best-of-breed rating and billing module offering the performance required by major carriers handling large volumes of data. Geneva can bill for any service or combination of services.

Convergys' product line of highly scalable end-to-end billing products, preintegrated application suites, and application modules enables communication providers to create fully integrated billing and customer care environments that are adaptable, reliable, and cost-effective. Convergys products are based on its proven and innovative Next Generation Framework, a component-based architecture that provides unsurpassed flexibility, investment protection, and support for convergent communication services.
