With the development of science and technology, the phone is getting more and more intelligent. Now the phone can be used to make the ordinary phone calls, but also to make the special free phone calls with some third party apps. The main reason is the Voice over Internet Protocol technology, or you can call it VoIP for short. The VoIP can send our voice on the Internet.
