What does the advertisement short message blocking list mean?

The blacklist set by mobile phone users is used to intercept advertising messages sent by numbers in the blacklist.

When a number is added to the advertisement short message blocking list, the mobile phone system will automatically block the short message sent by the number, so that it cannot enter the short message inbox. This can effectively prevent harassing calls and text messages and improve the experience of using mobile phones. The mobile phone system provides interception function. You can find the relevant options in the settings to add the number to be blocked to the blacklist.
