iBasis Enables Pingo to Offer its Lowest International Long Distance Phone Rate on Discount Prepaid Calling Card Calls.

iBasis, the global VoIP company(TM), today announced that Pingo (http://www.pingo.com/aboutus.do), its discount calling card call service, has reduced its International long distance phone rates by as much as 30%. Now, Pingo customers using the service's local access numbers in the U.S. can call more than 75 countries for 3 cents or less per minute.

"Pingo's RateWatcher(TM) promise is to continually look for ways to add value for our Pingo customers so that Pingo really is the last calling card they'll ever need," said Ofer Gneezy, president and CEO of iBasis. "This time, we're leveraging local access numbers across the U.S. to lower our costs, and we're passing that savings on to our customers so they can Pingo the world for less."

Pingo's local access numbers are available in more than 800 communities in 38 states plus the District of Columbia. By using local access, Pingo customers can save an additional one cent per minute off the already discount prepaid calling card for long distance calls. Whenever a local access number is not available, Pingo customers can always rely on toll-free numbers, which are available in 35 countries, including the U.S., Canada, and the U.K. The full list of U.S. local access numbers and international toll-free access numbers are available on the Pingo website.
