Major Brazilian Operator Selects Evolving Systems' Dynamic SIM Allocation(TM) Solution

ENGLEWOOD, CO--(Marketwire - June 15, 2010) -  Evolving Systems, Inc. (NASDAQ: EVOL)

Streamlining SIM Supply Logistics and Optimizing Number Inventory

Solution Delivered in Partnership With Leading SIM Manufacturer

Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of software solutions and services to the wireless, wireline and IP carrier market, today announced that a leading Brazilian operator has selected the Company's Dynamic SIM Allocation™ (DSA) solution to help streamline its SIM card supply chain logistics and optimize its telephone number inventory. A leading SIM manufacturer will jointly deliver the project.

Due to the operator's rapid growth, and in order to comply with number utilization regulations imposed by ANATEL, Brazil's telecommunications regulator, the operator faced an urgent need to optimize its SIM card provisioning process in a very short time frame. The operator carried out an industry-wide evaluation of solutions using functionality, flexibility and vendor experience as key selection criteria and, after a stringent RFP process, chose Evolving Systems' DSA solution. 

Once in production, DSA will revolutionize the operator's SIM provisioning process, enabling it to activate SIM cards 'on-the-fly' upon first use, thereby optimizing phone number usage, streamlining SIM logistics and reducing network overhead costs. DSA will also help the operator offer a unique customer experience to its subscribers by allowing dynamic phone number selection and other value added services right to the user's handset upon first use of the network.

"We are extremely pleased with this major win achieved with our leading SIM manufacturer partner," said Thad Dupper, CEO and Chairman of Evolving Systems. "This award proves that Evolving Systems' market leading technology and experience, combined with our partner's strong local presence, are a valuable business proposition for carriers in the large and competitive Brazilian market."
