What's the difference between SMS chat and WeChat chat?

There are actually many differences. First of all, the network is different. One is the communication network, and the other is the Internet. In fact, from the point of view of charging, a short message costs ten cents, and a simple WeChat message may be less than 1 cent. The software used again is different. Finally, from the convenience of chatting, WeChat is faster. I hope to adopt.
