Major Central American Operator Selects Evolving Systems' NumeriTrack(R) Solution for Number Resource Management

ENGLEWOOD, CO--(Marketwire - March 2, 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 leading Central American converged network operators has selected the Company's number resource management solution, NumeriTrack®, for its central number management and inventory system.

As telecommunications markets mature, operators are faced with increasingly complex numbering requirements stemming from fierce competition and regulatory changes, such as the introduction of number portability. There is now a critical mass of countries in the Central and Latin American region entering this dynamic stage, following the lead of the early adopters, Brazil and Mexico, in 2009 and 2008, respectively.

The operator's legacy numbering system has become increasingly expensive to maintain as the business continues to grow. It also lacks the flexibility needed to comply with changing business and regulatory requirements, including number utilization reporting and tracking number inventory to the individual number level to support number portability in the future. After an exhaustive evaluation of the leading solutions in the industry, the carrier selected Evolving Systems' NumeriTrack solution as the best fit.

"This award represents another win in a string of international numbering projects in recent months, and marks our continued commitment to deliver successful projects in Central America," said Steve Farnsworth, vice president of Evolving Systems' Numbering Solutions.
