RSL Communications to Realize Estimated $300 Million in Revenue From Commercial Agreement With Largest European Cellular Reseller.

HAMBURG, Germany and NEW YORK--(BUSINESS WIRE)--Feb. 2, 1999--

Debitel to Resell RSL COM Global Network in Germany,

Europe's Largest Telecom Market

RSL Communications, Ltd. (NASDAQ: RSLCF), today announced that its subsidiary, RSL COM Deutschland GmbH and Debitel Kommunikationstechnik GmbH & Co. KG, Europe's largest mobile reseller company, have agreed that Debitel will utilize RSL COM's fixed wire network for new services that it will be promoting to German consumers using its proven successful marketing force. The deal is estimated at $300 million in revenues to RSL COM over three years and is the largest commercial relationship entered into by RSL COM since it was founded in 1994.

Debitel was formed in 1992 by Metro Holding AG, Europe's largest and the world's second largest wholesale and retail management company, and Debis (Daimler Benz) and has nearly 3 million customers. Metro Holding is a significant shareholder in Debitel and holds more than six percent of the outstanding shares of RSL Communications, Ltd. As a result of the joint venture agreement between RSL COM and Metro Holdings, Metro Holdings' subsidiaries have begun seeking ways to promote and market RSL COM services. The Debitel agreement is the most recent and potentially largest result to date of the Metro/RSL COM joint venture.

Itzhak Fisher, President and CEO of RSL Communications, said, "When we entered into our joint venture with Metro, the most powerful and highly respected trading group in Europe, it was intended to give RSL COM access to a wealth of customers through a variety of distribution channels and to build relationships with Metro's strategic partners. The results are beginning to show. The selection of RSL COM by Debitel is a strong endorsement of the quality of our fixed wire network. The agreement with Debitel, having resulted from the Metro relationship, is a strong endorsement of RSL COM's strategy to generate significant revenues by attracting customers through nontraditional distribution channels. These customers can now utilize the vast pan-European telecommunications network that RSL COM has built."

Lutz Meyer-Scheel, Chief Executive Officer of RSL COM Deutschland GmbH said, ARSL COM's agreement with Debitel may represent one of the largest telecommunications marketing transactions in Germany since Germany underwent deregulation early last year. In addition, this is the first time that a fixed wire carrier and mobile provider have converged to provide residents of Germany with a full menu of telecommunications services. With the assistance of Debitel, Germany's largest cellular reseller, RSL COM is now positioned to be a major telecommunications force in Germany and throughout Europe."

Dr. Joachim Dreyer, Chief Executive Officer of Debitel, said, "Debitel's agreement with RSL Communications represents a milestone in the German telecommunications marketplace and brings our relationship with RSL COM to the next level. Debitel's portfolio of services will now be greatly increased. This is the most significant cooperation thus far between a cellular reseller and a fixed-wire carrier."

The first product to be offered by Debitel utilizing RSL COM's fixed network will be open Call-by-Call (no registration necessary), which is anticipated to be introduced on February 3rd under Debitel's brand name. The service will be handled by RSL COM Deutschland's national telephone network. Other services to be provided by Debitel in the future are expected to utilize the RSL COM international network, RSL NET, in addition to the network of RSL COM Deutschland.
