African Carrier Selects Evolving Systems for Dynamic SIM Allocation and Number Management

ENGLEWOOD, CO--(Marketwire - April 15, 2009) - Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of software solutions and services to the wireless, wireline and cable market, today announced that a long-standing customer located in Africa has selected the Company's Dynamic SIM Allocation™ and NumeriTrack® solutions to help streamline network capacity utilization and manage its number inventory.

The carrier's prepaid SIM cards are currently batch pre-provisioned, making utilization, network capacity and regulatory constraints increasingly an issue. Pre-provisioning of SIM cards requires space on the carrier's HLR (Home Location Register) and other network platforms, regardless of whether the SIM card ever becomes active or generates revenue, resulting in significant costs and potential overloading of the network due to uneven distribution of SIM cards across the HLRs.

Evolving Systems' Dynamic SIM Allocation solution will allow the carrier to avoid these issues by instead provisioning the SIM card when the phone is first switched on and used. Key network elements such as the HLR will only be provisioned at the time of first use, meaning that the carrier only need purchase HLR capacity for active SIMs and not those currently inactive in the supply chain. The solution also enables uniform loading of HLRs, optimizing network capacity and significantly reducing costs.

As part of this project, the carrier also selected Evolving Systems' NumeriTrack solution to provide a robust number management system for both prepaid and post-paid subscribers, as well as a centralized database to store, assign, track and manage all of the carrier's number inventory. Number management is currently carried out by the billing and rating engine and the carrier wanted to remove this functionality from the billing system and deploy a comprehensive solution to carry out all their number inventory requirements. In addition, the NumeriTrack solution will automate SIM card ordering, which is currently a manual process, plus provide real-time reporting on number utilization.

"Evolving Systems' Dynamic SIM Allocation and NumeriTrack solutions will support this carrier's growth initiatives by bringing innovation to their prepaid wireless SIM card management and activation processes," said Thad Dupper, president and CEO of Evolving Systems. "The local telecoms authority charges carriers for MSISDNs (number ranges) so it is vitally important that carriers can track and report on number status and utilization rates as well as ensure there are enough numbers available to support subscriber needs and ongoing marketing campaigns. Our Dynamic SIM Allocation solution will enable the customer to achieve significant savings by avoiding the costs associated with inactive SIMs with both number ranges and network capacity as well as help with uniform loading of their HLRs. Our NumeriTrack solution will allow for more efficient use of their number inventory and prepare them for number portability. This is our second Dynamic SIM Allocation win this year and we continue to see opportunities and growth in this space."
