I can get on my Blackberry no matter where I am, and without dialing any access numbers, immediately call people throughout the world for pennies, said Fred Rooney, a longtime Pingo customer who resides in Pennsylvania and New York. As Director of the Community Legal Resource Network for City University of New York (CUNY) School of Law, Rooney relies on the service for personal and business calling to India, Europe and Latin America. The rates are phenomenal, beating any other services Ive tried, and the voice quality is consistently superior. Add in EZ Dial and theres just no better or easier way to save on international calling.

iPhone and Blackberry users can easily download EZ Dial from the Apple iTunes AppStore or via text message to their mobile device. Then, whenever an international phone number is dialed or selected from the address book or contacts list, EZ Dial sends the call to the Pingo service for immediate savings. EZ Dial users dont dial access numbers, PIN codes or change their calling behavior in any way. The application complements existing voice plans and does not require users to connect to Wi-Fi.

Consumers can purchase international calling minutes on the Pingo.com site at very competitive rates and without hidden fees or any further contractual obligations. Pingo users save as much as 90 percent on international calling rates compared to traditional mobile calling plans. Plus, Pingo customers that download the application receive $5 in free Pingo EZ Dial calls*.
