Why did WeChat replace the SMS function?

First of all, WeChat needs the network, sometimes the network is uncertain, or now people often delay receiving information because of cleaning up the background, so the timeliness and reliability are not as good as SMS. Of course, there will be "nine to five" in short messages, but after so many years of use, people have relatively acquiesced in this situation.

Secondly, there are communication costs and procedures. This is also a message, especially in serious situations, such as situations involving interests, such as issuing bank card numbers. If it is sent by WeChat, it is ok between friends. If it is between companies, it is a bit frivolous. First, you need to add this person's WeChat, but if it is only a short-term business cooperation, there is no need to add WeChat. A short message of 10 cents and a free WeChat both conveyed the same message. Sending a message makes people feel that you attach importance to this matter, and he is the receiver of this message, although it is only a dime difference.

Third, coverage, including geographical scope and user scope. Geographically, there are still some places where the network coverage is not ideal, and WeChat can do nothing but rely on SMS. There is also that many elderly people don't use WeChat, and only some young people use it. At this point, you can only communicate by SMS. Generally speaking, whether WeChat uses a product depends on the Internet. These characteristics mean that it is not safe enough at present. However, SMS is a service provided by operators. As long as you have an operator, the service is open. As long as you have a signal, you don't need the Internet.

So at present, for most people, WeChat is more entertaining and life-oriented, and SMS is increasingly showing its value in relatively formal scenes.
