We knew that someday we'd be able to make VoIP phone calls over the iPhone's 3G network. Apple and AT&T said so.
That day has come. iCall is the first app to offer free VoIP (Voice over Internet Protocol) calls on AT&T's mobile network.
That means customers with unlimited data plans can save money by buying the minimum number of voice minutes, because iCall places calls using data sent over the Internet, not voice minutes.
In a test, iCall was a breeze to use, if a bit tinny. The app is free, as are the calls it makes, but there are a few catches. People on the free calling plan will hear an ad before a call is connected, and calls are limited to five minutes. A $10 monthly subscription eliminates the ads and the time limit and provides services like voice mail.
The other caveat is that most unlimited data plans have limits on certain kinds of apps, like peer-to-peer file sharing. So far iCall appears to be in the clear, but it's early yet.
