I had spent some time in Taiwan this past five days. But my lovely wife and daughter didn't come with me this time. Thanks for the technology we have in this era, I was able to see my love ones through Skype. But when they were not home, I had talked to my wife by using Viber. But sometimes the 3G/4G quality was not good. So I took advantage of the Google voice which embeded in Gmail to make a free call to the states.
The voice quality is perfect, no delay, no echo. That makes me wondering when Google is going to make Google voice as a true VOIP service.
