OZ TO PRESENT AT THE 2005 GLOBAL MESSAGING CONGRESS

Montreal, Canada - June 14, 2005 - OZ, the leading enabler of mobile messaging services, today announced Skuli Mogensen, OZ CEO and Founder, will present at the Global Messaging Congress on Wednesday, June 15, 2005 from 2:30pm – 2:55pm at Earl’s Court in London, England.

Mr. Mogensen’s discussion will review the issues surrounding the mobile instant messaging (IM) phenomenon in North America, answer European operators concerns about IM cannibalization of SMS, review how Mobile IM contributes to the mobile operators business model, and examine the value of Mobile IM to the carrier and to the consumer.

Instant messaging (IM) is one of the most popular methods of communicating today. Every day IM users send billions of PC-to-PC instant messages between themselves. All of this messaging traffic is however generating little or no revenues for the mobile operators, as IM usage is mostly limited to the PC world where no billing models for consumer IM services exist.

Mobile operators, on the other hand, charge subscribers for mobile messaging services such as SMS and MMS, as well as for Internet connectivity on their mobile phones. By mobilizing existing IM services, mobile operators are therefore in a position to offer subscribers mobile access to an already established communications phenomenon while also generating, for the first time, real revenues from the usage of IM services.
