Why is SMS blocking turned on or can I still receive it?

Interception mechanism of mobile phone itself, SMS interception and interception notification reminder of operators.

1. Interception mechanism of the mobile phone itself: Interception of mobile phone short messages is just an interception mechanism that comes with the mobile phone. It can help users filter some unimportant information, but not all short messages can be intercepted. So even if SMS interception is turned on, some normally received SMS messages can still be received.

2. SMS interception of operators: In addition to the interception mechanism of mobile phones, some mobile phone numbers will be blacklisted by communication operators due to complaints, SMS unsubscribe and other reasons. At this point, messages sent to these blacklisted numbers will be blocked, even if the user turns on SMS blocking.

3. Interception notification reminder: Some mobile phone systems will give corresponding reminders after intercepting short messages, such as "Interception notification" or "No attention notification". Therefore, even if SMS interception is turned on, users can still see the intercepted SMS notification in the notification bar.
