AT&T smartphone customers now have another way to stay in touch with family and friends abroad. Introducing AT&T Call International – a free mobile VoIP app – providing international long distance calling at low, competitive rates.

Developed with and operated by 8x8, AT&T smartphone customers can use the app to make calls from the U.S. to international numbers; and when abroad, customers will benefit from the same low rates using the app over Wi-Fi. Countries and rates are available at www.att.com/callinternational.

The app provides simple, step-by-step instructions to establish an AT&T Call International account. Once established, customers can immediately make international calls through the app by either dialing directly or by accessing their existing contacts list. All calls are billed directly to the customer’s credit card.

The AT&T Call International app is available today as a free download in Android Market, BlackBerry AppWorld and more.
