How does WeChat send short messages for free?

Wechat is a new mobile phone information service launched by Tencent.

Wechat is as free as qq, but the difference is that WeChat will be a software that works randomly in your mobile phone. After the first login, it is turned on by default. As long as your mobile phone is connected to Internet channels such as gprs and wifi, you can send and receive information!

What you spend is your internet browsing fee, just like the concept that you need internet fees when you use qq on your computer!

At this stage, WeChat is in the testing stage, and there are still many problems. I believe that a fully functional and relatively stable WeChat will soon impact the existing SMS market of the "three major telecom operators".
