MTN Improves Number Utilization and Reduces Network Costs With Evolving Systems' Dynamic SIM Allocation(TM)

ENGLEWOOD, CO--(Marketwire - Sep 11, 2012) - Evolving Systems, Inc. ( NASDAQ : EVOL ), a leading provider of strategic solutions to telecoms operators worldwide, today announced that leading Information Communication Technology (ICT) company MTN Nigeria, the largest and most profitable operator within the MTN Group, reaps the benefits with Evolving Systems' Dynamic SIM Allocation™ (DSA) solution, providing improved number utilization through automatic number allocation and reduced network overhead costs.

DSA will allow MTN to achieve more efficient use of its network capacity and load balancing across its Home Location Registers (HLRs). By using the solution, MTN will also achieve number allocation efficiencies, as numbers do not have to be predefined on the HLR.

Until now, MTN had used a traditional pre-provisioning approach for new SIM cards. This means it had to buy its numbers from the national regulator and pre-load them on its HLRs. The new system means that it will no longer have to buy numbers as frequently as before.

This project is also an investment in better services for MTN's customers. MTN plans to use DSA's on-device user interaction to offer customers more choice and personalization when activating a new phone.

"We are confident that, moving forward, Evolving Systems' DSA solution will be key in enabling us to drive new operational efficiencies and keep costs down as we roll out SIM cards across the country," says Basit Arogundade, General Manager IS, Business Planning and Solutions Architecture, MTN Nigeria.

Thad Dupper, Chairman and CEO at Evolving Systems, said, "In the highly competitive wireless market, differentiation is key. By using DSA, MTN will be able to achieve significant savings both in resources and costs but most importantly it will be able to deliver strategic enhancements which will enable it to drive operational agility and ultimately competitive edge."
