What does it mean to intercept strange text messages? Can you see them?

Interception of strange short messages means that the intercepted number is set by the mobile phone, which seems to be blacklisted, and all of them will not be displayed, but can be seen. Because since it is intercepted, it will not be displayed, but it can be seen. Every mobile phone has SMS function, and there is a cross plus button in the upper right corner. By checking the missed calls and choosing to intercept the message, only the other party can see the content of the message you sent to the other party. Generally, they don't choose the interception function. They usually don't care too much about this information and classify it as spam.
