Goober 3.0 offers HD voice calls (with higher-quality audio). Rates are a little complicated: it’s 1 cent a minute for landlines in the U.S. and Canada, and 1.4 cents for mobile lines. Calls to landlines in Europe are usually less than 3 cents a minute, but some areas are more, and mobile lines are 20 cents and up. Asia calls start at 5 cents, and go up from there depending on the country and type of line. The company is making a point of saying that its advertised rates tend to be lower than Skype’s.
