AT&T this week joined the VoIP fray with the release of its own application that hopes to offer customers cheaper international calling rates. The company yesterday announced AT&T Call International, a free mobile VoIP app that provides customers with cheap international long distance calling over 3G. Available for iPhone and and selected Android and BlackBerry smartphones, the application was developed by and is operated in collaboration with 8x8 Inc.
Calls made using the application while in the U.S. will eat into your minutes and if you plan on using it abroad, you'll need to first find a WiFi connection. AppleInsider reports that calls made to wireline numbers in China, France, Germany and the UK cost 4c per minute, while Mexico is 8c and India is 9c. Calls to cell phones cost considerably more, with European numbers costing between 21c and 27c per minute.
AT&T said in a statement that once installed, the app provides simple, step-by-step instructions to establish an AT&T Call International account and make calls. The carrier also mentioned that all calls are billed directly to the customer's credit card.
