Vonage introduced the World Premium Unlimited calling plan. This new offering builds on the value of the popular World plan by expanding the number of countries for unlimited calling from 60 to 80, including unlimited calling to mobile phones in 42 countries.

"People who make international calls to mobiles are frustrated by the huge premiums they pay to their phone company," said Mike Tempora, senior vice president of product management for Vonage. "World Premium provides these callers with the peace of mind to call any landline or mobile number in 42 countries including Brazil, Costa Rica, Japan, Australia, France, Spain and the UK for one flat price. Customers who use World Premium Unlimited to call as little as one hour a week to mobile phones in countries like Mexico and the UK will save over $400 a year versus the best pay per minute rates from major phone companies."

The World Premium Unlimited plan is $54.99/month (plus taxes and fees). The service uses a high-speed Internet connection and an existing home phone. For more details on the World Premium Unlimited calling plan, please click here.
