Calling people outside the US isn't as expensive as it used to be, but the charges can still add up; even the better deals at big American wireless carriers have you paying both a monthly rate and by the minute. T-Mobile thinks it can shake things up a bit. It just revamped its Stateside International Talk plan to offer unlimited international calling to as many as 70 countries at flat rates. You'll pay a relatively modest $5 extra per month if you only need to reach landlines, and $10 per month if your foreign friends use cellphones. And importantly, this covers every line on your account -- your kids can speak to family overseas without racking up huge bills. There are some catches (only "30+" countries qualify for unlimited mobile-to-mobile), but this could still be a solid deal if you frequently chat with people around the globe.
