Evolving Systems' Dynamic SIM Allocation(TM) Solution Supports Customer in Strategic MVNO Initiative

ENGLEWOOD, CO -- (Marketwired) -- 05/21/13 -- Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of strategic solutions to telecom operators worldwide, today announced that a Latin American customer plans to use its Dynamic SIM Allocation™ (DSA) Solution to support a strategic Mobile Virtual Network Operator (MVNO) initiative.

Competing effectively and gaining market share is of paramount importance to this customer as the second largest mobile operator in their country. For MVNOs, being able to use an existing operator's infrastructure means banks, supermarkets and other outlets can set up their own mobile service without having to invest in expensive network equipment. For operators, having the ability to quickly ramp new MVNOs into their networks is key to maximizing their revenues in this growing market segment.

With few existing MVNOs in this country, supporting the creation of new ones with DSA will help the customer take onboard new MVNOs quickly, and enable them to offer their subscribers the unique DSA activation experience. DSA's capabilities will help the operator leverage this growing new market with more services and generate additional market share and business opportunities by targeting corporations as well as individual subscribers.

"The MVNO market represents a significant opportunity for telecom operators to increase their revenues and tap into new channels of innovation available in new market segments," said Thad Dupper, Chairman and CEO of Evolving Systems. "DSA's configurability allows the mobile operator to compete effectively in the wholesale market, enabling them to extend the OPEX-saving and revenue increasing benefits of DSA to their MVNO offering."
