Southeast African Wireless Carrier Selects Evolving Systems' Tertio(TM) Service Activation Solution

ENGLEWOOD, CO--(Marketwire - September 29, 2009) - Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of software solutions and services to the wireless, wireline and cable markets, today announced a Southeast African wireless operator has selected the Company's Tertio™ service activation solution to support its business growth strategy.

The operator's activation system is becoming increasingly inflexible and hard to manage, leading to the delay in some orders being processed as the operator looks to scale and grow its business. The carrier selected Evolving Systems' Tertio solution to provide a flexible next-generation service activation system capable of carrying out current and future provisioning requirements, as well as support its business growth strategy.

"We are pleased to add a new customer for our leading wireless service activation solution, Tertio," said Thad Dupper, president and CEO of Evolving Systems. "As a direct result of our focus on emerging markets, we have been very successful winning business in Africa, and this new name represents our 10th customer."
