Why is SMS replaced by WeChat? Is texting really useless?

As long as the mobile phone has SMS function, it will not be replaced.

The bank sends you the balance change information. Why don't you use WeChat?

When notifying an important meeting, you can only enter the venue by telephone confirmation or SMS authentication.

You don't have a chat record on WeChat, and the data won't be stored in the phone memory, but SMS will. As long as your mobile phone is not restored to the factory settings and deleted, the text message will always be there, but you can try it on WeChat every other year. Can you find the chat record from a year ago?
