(NYSE:CVG)

Southeast Asia's Largest Mobile Operator Selected Convergys Rating and

Billing Software for Its Ability to Handle Complex Transactions and

Pricing Models

Convergys Corporation (NYSE:CVG), the global leader in integrated billing, employee care, and customer care services, announced today that its Geneva(TM) rating and billing software is now in live operation at Advanced Info Service (AIS) Plc. AIS is the largest mobile operator in Thailand and Southeast Asia with more than 9 million subscribers. Geneva provides usage processing, rating, and discounting for AIS' post-paid business and residential subscribers.

Geneva is being integrated with third-party customer relationship management, mediation, and provisioning applications to replace AIS' legacy billing system as part of a phased implementation. The final stage is scheduled for mid-2003 under the terms of a Geneva license contract announced in January for the company's GSM (Global System for Mobile Communications)/GPRS (General Packet Radio Service) network.

AIS selected the award-winning Geneva software for its ease and speed of implementation, scalability, and its ability to handle large numbers of diverse transactions and complex pricing models. The software, which features convergent pre-paid capabilities, also will support international roaming (TAP3) and content settlement.

"The on-time progress of the implementation and the essentially error-free performance of the Geneva software affirms our decision to work with Convergys," said Arpattra Sringkarrinkul, AIS' Vice President of Information System Support. "We're confident that Geneva will enable us to accelerate revenue growth and expand our subscriber base through cross-discounting and bundling of our next-generation wireless voice and data service bundles."

"Innovative operators like AIS are accelerating the availability of advanced communication services for Thailand's business and consumer markets," said Steve Robertson, President of Convergys International. "We appreciate the confidence AIS places in its partner-style relationship with Convergys to provide the world-class billing and customer care solution AIS will use to differentiate its offerings and build loyal customer relationships."

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, pre-integrated application suites, and application modules enables communication providers to create fully integrated billing and customer care environments that are adaptable, reliable, and cost-effective.
