Pingo Delivers EZ Dial Smartphone App for Discount International Calling from iPhone and Blackberry

New Application Automatically Accesses Wholesale Calling Rates For International
Calls from More than 450 Smartphone Models
BURLINGTON, Mass.--(Business Wire)--
Pingo, the prepaid international calling service from iBasis (NASDAQ: IBAS),
today introduced Pingo EZ Dial, a new smartphone application that delivers
automatic access to discount international calling rates for users of popular
mobile devices including the iPhone, Blackberry, Treo and phones using operating
systems such as Nokia Symbian, Windows Mobile and Google Android.

Though largely unknown to consumers, iBasis is one of the largest carriers of
international phone calls in the world. Pingo is iBasis` only direct-to-consumer
offering, a prepaid calling service that can be purchased via a Web site
(http://www.pingo.com). Pingo EZ Dial now makes it extremely easy for users of
the iPhone, Blackberry, and other smartphones to access the Pingo service and
get the same reliable quality, global coverage and cost savings that iBasis has
provided for many of the world`s largest retail telecom carriers for years.

"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 I`ve tried, and the voice quality is consistently superior.
Add in EZ Dial and there`s 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 don`t 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*.

"iBasis is the second largest carrier of international voice traffic in the
world, and for the first time, consumers and businesses now have a smartphone
application that provides easy access to our low wholesale calling rates," said
Jayesh Patel, vice president of business development and strategy for iBasis.
"The quality and reliability is the same as we provide for carriers worldwide.
And, with no further contractual obligation, Pingo customers can make
inexpensive international calls and escape the `financial stranglehold` of
operators` international plans."

Companies can also gain access to the same low wholesale international rates
through Pingo Business, which offers small and medium-sized businesses similar
service for up to 999 employees, accompanied by easy-to-use online management
tools. IT managers and administrators can also automatically "push" the EZ Dial
application out to staff mobile devices. This ensures employees use the Pingo
Business service, providing an organization with dramatic savings on
international calling without requiring any change in individual calling
behavior.

Pingo offers easy online account management. Minutes can be purchased via credit
and debit cards. Subscribers can pay in four currencies; compare rates to any
destination in the world; and interact with automated phone voice prompts in a
variety of languages, including Chinese, English, French, Korean, Polish,
Portuguese, Spanish and Russian. Pingo customers can access the service by phone
in 35 countries, including the U.S., Australia, Canada, China, the U.K., France,
Germany, Israel, Japan, Russia and Thailand. Consumers can sign up for Pingo at
