MTS Awarded  Additional  Contract  by a National  Spanish  Operator  for Billing
Solutions

Tuesday May 24, 11:41 am ET

RA'ANANA, Israel, May 24 /PRNewswire-FirstCall/ -- MTS - Mer Telemanagement
Solutions Ltd. (Nasdaq: MTSL - News), a global provider of operations support
systems (OSS) and customer care and billing (CC&B), today announced it was
awarded an additional contract by a national Spanish operator for billing
solutions for its new triple play services package project. Its new services
package offers customers "Triple Play" services (voice, data, video) via DSL for
the home TV, and serves as an alternative to services offered by the cable
operators. The value of MTS' contract for these services with this national
Spanish operator has reached $750,000 to date.

The MTS billing system consists of a powerful pricing rating engine that
integrates into the carrier's main Legacy Billing system. By implementing the
solution's many features, including its flexible self-web-care and very
sophisticate rating machine, the MTS CC&B system allows the carrier to bill for
services like Video On Demand, Music On Demand, News On Demand, Digital and
Analog Video channels and others interactive value-added services. The billing
system will be used by the national Spanish operator to bill for "Triple Play"
DSL services to its home TV customers.

The national Spanish operator began building a national network to support these
"Triple Play" services in 2002 and commenced its "Triple Play" offering in early
April 2005. At that time, MTS was awarded a contract to expand its billing
services to include 100,000 end users. In May, the contract was expanded to
include a reach of 500,000 subscribers. The national Spanish operator wants to
expand its "Triple Play" services project to include a reach of 3 million
Spanish subscribers by the end of 2007. In addition, it plans to deploy these
services and billing solutions to customers elsewhere in Europe and Latin
America.

Ilan Arbel, MTS' VP for Billing Sales, said, "Our demonstrated ability to
provide high quality, accurate billing services in a fast and easy format
enabled us to expand this contract to half a million users. Our CC&B system
platform is scaleable, which allows the carrier to sustain growth and ensures
the solution serves them as the technology evolves. We are excited to work with
this national Spanish operator, and look forward to expanding our service
offering as its business grows."

MTS' billing-rating solution enables the carriers to provide customers with one
bill, containing all special charges and regular monthly telephone charges, as
well as provides the operator with an easy, fast and simple means for
customizing and changing its pricing plans. MTS' hardware and components are
fully scalable and its hardware modules may be added at any time as the need
arises due to increasing subscribers and services.
