MTS ANNOUNCES FIRST QUARTER 2007 FINANCIAL RESULTS

RA'ANANA, ISRAEL - MAY 9, 2007 - MTS - MER TELEMANAGEMENT SOLUTIONS LTD. (NASDAQ
CAPITAL MARKET: MTSL), a global provider of business support systems (BSS( for
comprehensive telecommunication management and customer care & billing (CC&B)
solutions, today announced its financial results for the first quarter of 2007.

Revenues for the first quarter of 2007 were $2.45 million, compared with
revenues of $2.8 million in the first quarter of 2006. Operating loss for the
first quarter of 2007 was $602,000 compared with a loss of $588,000 in the first
quarter of 2006. Net loss for the first quarter was $585,000 or ($0.10) per
diluted share, compared with a net loss of $485,000 or ($0.08) per diluted share
in the first quarter of 2006.

MTS ended the quarter with approximately $1.9 million in cash and cash
equivalents, including marketable securities.

MTS ended the first quarter with an accumulated backlog of orders of
approximately $1 million. The backlog represents orders booked but not yet
recognized as revenue (excluding deferred maintenance revenues) as of March 31,
2007.

Mr. Eytan Bar, President and CEO of MTS said, "We gained market visibility and
were exposed to a solid pipeline for the billing market, in the IPTV, mobile,
and WiMax areas. We also increased our business opportunities in the field of
Interconnect Billing following the successful implementation of this product by
one of our customers, Bezeq International. As a result, additional sales
opportunities have opened for our company. In the area of Telecommunications
Expense Management (TEM), we concluded the first installations of our Invoice
Management solution.


     During the first quarter of 2007, we didn't succeed in converting a number
of business opportunities in the different segments of the market in which we
operate into orders that would lead to revenues for our company. Nevertheless,
we expect to penetrate the market in the next few quarters. We see the market
opportunities and are ready to leverage our solutions," concluded Mr. Bar.
