Sonopia Drives Massive Proliferation of Mobile Carriers with Easy-to-Use Services

Menlo Park, CA – April 23, 2007 – Sonopia announced today that it has been named to the annual FierceWireless “Fierce 15” list, designating it as one of the top wireless companies of the year. FierceWireless editors evaluated hundreds of organizations, and found Sonopia to be amongst the “fiercest“, proven by their creativity and innovations in the marketplace.

FierceWireless, an internationally recognized daily email newsletter reaching more than 74,000 senior wireless industry executives, provides executives in over 100 countries with a quick, authoritative briefing on the day's top wireless stories, including new trends and technologies.

"Sonopia's strategy of allowing any individual, company or organization to create their own MVNO is an innovative twist on the mobile virtual network operator model," said Sue Marek, Editor-in-Chief of FierceMarkets.

Sonopia is democratizing mobile services by making it possible for anyone – whether a major corporation, a charity or an entrepreneurial individual – to become a mobile carrier in a matter of minutes. The company is changing the way people think about their cell phones by providing consumers with branded mobile services tailored to their lifestyles and preferences, eliminating today's “one-size-fits-all” approach.

"The wireless community depends on FierceWireless to provide the most up-to-date news along with analysis of major industry trends.
