How does Xiaomi 3 prohibit receiving such short messages?

Go to ~ Security Center ~ Harassment Interception ~ Click the settings file in the upper right corner of the current page to turn on harassment interception ~ Then set the interception rule ~ Set it to ~ Interception of strange numbers. You can also customize the interception mode and add keyword interception. For example, if you add "bank card" as a keyword, you will not receive the information of this word. In addition, you can turn off blocking notifications, so that you won't receive notifications of blocking SMS messages, as shown below. Hope to adopt!
