AT&T`s new app will allow users to make international calls over 3G and WiFi, in that it`s different from other VoIP apps. The app has other benefits as well, like the ability to dial contacts straight from your iPhone’s address book and near real-time call billing reports.
After setting up an account, users will be able to make calls all over the world with rates like $0.09/per minute in India, and $0.04/per minute in France.
In addition to the availability on iPhones the app is also available on selected Android and Blackberry cellphones. You can also request for separate billing to your AT&T account. And the good part is there is no contract or minimum calling required.
