How does Xiaomi unlock SMS?

After turning on Xiaomi's mobile phone, click the short message on the desktop.

In the SMS interface, you can see that there is a separate option to intercept SMS.

Turn on Block SMS, and select a SMS.

There are two options below, one is not to intercept, the other is to reply to the short message, and click not to intercept.

Then a confirmation dialog box will pop up, allowing you to confirm that you will no longer intercept, and directly click the Don't intercept button.

Then this short message will appear in the normal short message interface.
