AT&T (s t) is launching a new mobile app that allows its smartphone customers to make international calls via VoIP. The new AT&T Call International will allow customers to make calls overseas at cheap rates like 4 cents per minute to China, Germany, France and the UK and 9 cents per minute to India.
The app was developed with communications and VoIP provider 8×8 (s eght) and will work on Android (s goog), iPhone (s aapl) and BlackBerry (s rimm) devices, although many Android and BlackBerry models are not supported. You can check what devices work with the app here.
The new app will allow users traveling overseas to also take advantage of these rates when calling over Wi-Fi on Android (s goog) and iPhone handsets. Once users establish an account, they can make phone calls right from their address book, with calls billed to their credit card. They will be able to manage their bill online.
It’s an interesting move for AT&T in that allows it to offer international calling to a wide range of users via VoIP. It shows that even the big boys can get into the VoIP market and offer cheap mobile calls overseas. But it also makes you wonder why AT&T couldn’t make this phone on its own.
