ENGLEWOOD, CO--(Marketwire - October 2, 2007) - Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of software solutions and services to the wireless, wireline and IP carrier market, today announced that Malaysia's leading telecommunications carrier has selected the Company's Tertio™ Service Activation solution. Evolving Systems will be delivering the solution with a regional partner.

The carrier selected the Company's Tertio solution to provide a single convergent service activation layer to support its pre-paid and post-paid fixed, mobile and broadband services. The carrier currently uses separate provisioning systems for each of its services, with a mixture of home-grown and legacy systems as well as manual processes. Launching new services with multiple provisioning systems was becoming increasingly costly and complex, particularly since not all of the systems were integrated with the carrier's CRM platform.

After a competitive evaluation, the carrier selected Evolving Systems' Tertio Service Activation solution, including the Tertio Service Composer, Tertio Activation Designer and Tertio Content Connector modules.

Evolving Systems will provide the core solution technology, as well as related technical and agent development services. The regional partner will develop custom functionality, service logic, configuration of business rules and provide dedicated in-country support.

"This is an exciting new customer for Evolving Systems, not only because it is our first Malaysian customer but also because it is our second new customer for the region in the last five months," said Thad Dupper, president and CEO of Evolving Systems. "We are pleased to be able to support its consolidation plans. Our Tertio solution will provide it with a single unified activation layer supporting fixed, mobile and broadband services. In addition, our customer is a key communications carrier in the region with majority stakes in a number of operators. We look forward to expanding our relationship with this customer to address opportunities with its affiliates."
