MTS Breakthrough Enables Enterprises to Control Mobile Phone Usage and Pricing

Monday May 8, 8:30 am ET

- New Mobile Phone Reconciliation Module Quickly and Easily Identifies Usage and
Rating Overcharges Without Relying on Service Provider Data -

RA'ANANA, Israel and FAIR LAWN, N.J., May 8 /PRNewswire-FirstCall/ -- MTS - Mer
Telemanagement Solutions Ltd. (Nasdaq: MTSL - News), a global provider of
business support systems (BSS) for comprehensive telecommunication management
and customer care & billing solutions, today announced that a major
technological breakthrough using its patent pending solution has produced a
system that can continuously monitor mobile phone usage and pricing
independently of the service provider's data. The MTS Mobile Phone
Reconciliation (MPR) module, a part of the MTS Invoice Management solution, e
nables enterprise customers to run an independent rating and billing process of
their actual usage and then reconcile it with the service provider's invoices to
detect usage and rating overcharges. The MPR module enables enterprises to
obtain information about calls and other usage events (such as SMS messages,
data and MMS) made from the organization's mobile phones in almost real time
regardless of the identity of the service provider.

This new service module, which can be purchased and run separately, takes the
mystery out of service provider invoices by quickly and easily deciphering the
complex maze of mobile phone fee structures, pricing calls using the correct
roaming tariff and verifying them according to contracted rates and special
plans, such as corporate VPN calls, special international corporate tariffs,
etc. The Mobile Phone Reconciliation module is the latest addition to the MTS
Application Suite platform, which comprises a number of modules that work in
tandem to manage all telecommunications expenses, such as invoice management,
bill verification, call accounting, and workflow management.

Corporate mobile phones equipped with MTS' unique solution enable corporate
administrators to obtain continuous usage reports from such devices as if they
were PBX extensions, thereby enabling over-usage real-time alerts to offending
employees, and fraud detection according to corporate rules and other
applications.

Eytan Bar, president & CEO, remarked, "I'm extremely pleased that MTS has
developed a solution that allows our enterprise customers to independently
verify their mobile phone bills. This new module provides MTS with yet another
opportunity to act as an 'honest broker,' rendering real prices for calls and
potentially exposing unintentional billing errors."

Mr. Bar added, "Using the MTS Mobile Phone Reconciliation Module, enterprises
now will have a true picture of the telecommunications expenditures of each
mobile phone user. By using the full complement of our Application Suite, they
will have a fully converged solution that is user-centric, displaying all
landline, mobile phone, calling card and other telecom expenses according to
invoices received."

Initially, MTS will roll out the Mobile Phone Reconciliation module to
enterprise customers. The Company also plans to roll out the product to
individual customers, via a subscription service to a systems house that will
serve as an outsourcing service in an ASP model.

Finally, the Mobile Reconciliation Module also can be fully integrated into the
MTS Telecommunications Expense Management (TEM) solution. TEM features an
automated simplified tool for managing, monitoring and routing invoices for
payment or correction. Invoice data is transmitted from all sources, including
calling cards, purchase orders, mobile lines and landlines, and automatically
analyzed relative to real usage, thereby reducing overhead costs caused by
invoice discrepancies, disputes and errors. These features provide the means by
which an enterprise can realize a timely positive return on investment.
