Huawei's mobile phone message was intercepted. Why can you still receive it?

Interception function only automatically filters out short messages with specified numbers or keywords, and puts them in the trash can or marks them as read.

After Huawei's mobile phone turns on the interception function, it can receive short messages. Interception function only automatically filters out short messages with specified numbers or keywords and puts them in the trash can or marks them as read, so users will not see intercepted short messages in the notification bar. However, SMS will still be stored in the mobile phone and can be viewed and managed in the trash can.
