Leading Mexican Operator Selects Evolving Systems' Active Number Management Solution


ENGLEWOOD, CO--(Marketwire - June 29, 2010) -  Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of software solutions and services to the wireless, wireline and cable markets, today announced that one of the largest wireless operators in Latin America has selected Evolving Systems to provide an active number resource management solution, based on three of the company's products; NumeriTrack®, Tertio Service Verification™ and Tertio Process Management™.

After years of explosive growth, and following the introduction of number portability in Mexico in 2008, the operator's existing legacy number management system had reached its limits. The operator sought to modernize its number management back-office systems with an off-the-shelf, proven solution. Due to the size of the project, and the complexity of number management processes necessary, the new solution needed to be extremely flexible and proven in a tier 1 environment. Following a lengthy and detailed evaluation of solutions from the leading vendors in the industry, the operator selected Evolving Systems' solution as the best fit.

Evolving Systems' NumeriTrack solution, a centralized resource management system, will track the entire number inventory of the operator's subscribers, including the lifecycle of individual subscriptions and the activities associated with maintaining the numbering topology across a wide and complex network. The Tertio Service Verification solution, which discovers and reconciles data inconsistencies among operational support systems and network elements, will enable increased levels of subscriber data accuracy, further enhancing the end user experience. The Tertio Process Management solution, which automates operational processes across multiple internal and third party systems, will coordinate the processing of engineering orders to implement the numbering topology throughout the network.

"We are very pleased to have been selected for this crucial project," said Thad Dupper, chairman and CEO of Evolving Systems. "Evolving Systems continues to win new business as we help carriers significantly improve their number management processes. The explosive growth that wireless carriers have experienced -- especially those carriers in markets where wireless subscription growth is very strong -- has created a challenge with the availability, assignment and efficient management of their number inventory. Our product, NumeriTrack, is designed specifically to enable carriers and regulators to overcome those challenges."
