Pingo ‘Free Calls for Life’.

Pingo, the prepaid calling card service of iBasis, is celebrating its first birthday by giving two lucky winners free calling time for life.

Other prize winners will get $100 in free calling time, and bonuses for joining and successfully referring friends to the prepaid virtual calling card service have been doubled to $10.

“We launched Pingo a year ago to provide consumers with the savings of a superior prepaid calling card and tremendous convenience features like PINpass PIN-less dialing, RateWatcher(TM), and international access,” said Ofer Gneezy, president and CEO of iBasis.

“We’re proud of the Pingo service, and we’re celebrating by giving our friends the gift of cheaper long distance with better service, and for two lucky winners, Pingo will truly be the last calling card they will ever need.”
