AT&T Call International app offers low rates at home and abroad

AT&T has introduced an AT&T Call International Application. What it lacks in name originality, it makes up for in cheap long-distance rates from all Apple iPhone models and a number of Android and BlackBerry smartphones.

Plus, when abroad, the app can be used - by the iPhone and Android devices, anyway - over a Wi-Fi connection for the same low rates.

In the U.S., users simply launch the app, dial the international number and hit call, for rates such as 4 cents a minute to wireless or wireline phones in China.

When abroad, they connect to a Wi-Fi network, dial the number and can be calling the United Kingdom for 27 cents per minute...
