Tier 1 Southeast Asian Carrier Selects Evolving Systems' Dynamic SIM Allocation(TM) Solution

ENGLEWOOD, CO, Jun 16 (MARKET WIRE) --
Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of software
solutions and services to the wireless, wireline and cable markets, today
announced that a Southeast Asian carrier has selected the Company's
Dynamic SIM Allocation(TM) solution to help streamline its SIM supply
chain logistics, manage its number inventory and enable prepaid number
selection.

The carrier selected Evolving Systems' Dynamic SIM Allocation solution
after a competitive evaluation because of the solution's ability to manage
SIM cards and numbers more effectively: the number is selected and
assigned at point of sale, leaving a larger pool of available numbers for
customers to choose from. The ability to select a number with cultural or
personal significance is a feature welcomed by the carrier's pre-paid
customers. In addition, the carrier operates under a regional numbering
plan and all of its pre-paid SIM cards are currently pre-provisioned.
However, with the Dynamic SIM Allocation solution pre-provisioning is
unnecessary; the operator can distribute a single SIM card type across
the whole country, so stock can be moved to meet changes in local demand,
as a regional number will not be assigned until a card is sold. Evolving
Systems' solution will offer the additional benefit of number choice to
subscribers in rural areas where Internet coverage is limited, as the
number can also be selected via the handset, rather than a sales terminal.

"Evolving Systems' DSA solution will provide the functionality required to
help this carrier better manage its SIM and number inventory. They will
now only need one generic SIM that can be used in all of their regions,"
said Thad Dupper, president and CEO of Evolving Systems. "Furthermore,
they will now be able to assign numbers at the point of sale, providing
them the ability to monetize more 'valuable' numbers."
