Vonage and Facebook today launched a new calling program that allows users to call their Facebook friends for free. In order to participate in the program, users must have either the new Vonage Mobile for Facebook application for iOS or Android installed.
Once the app is downloaded, users can sign in with their Facebook account and see a list of their Facebook friends they can call for free, as well as other users they can chat with via IM.
The app works anywhere you have 3G or Wi-Fi coverage - even overseas. There are no international calling fees or data roaming charges when on Wi-Fi, and you don't use your cellular minutes. If you do not have an unlimited 3G data plan or Wi-Fi subscription, check with your mobile carrier, as charges may apply. When traveling abroad using the local 3G network, just be sure to have an international data roaming plan from your carrier to avoid excessive roaming charges.
Users can also take advantage of the app's chat capabilities or the program's Facebook page to easily invite their friends to download the application to allow for free calling.
