How can I not receive the blocked blacklisted SMS completely?

This function can use the following methods:

1. Set SMS filtering: Most mobile phones have SMS filtering function. You can find similar options in the settings. Add the blacklist number to the filtering list, so that the received SMS will be automatically filtered without informing you.

2. Use third-party applications: There are many third-party SMS applications that can help you block messages with specific numbers. These applications usually have more powerful filtering and shielding functions.

3. Contact the operator: You can also contact your mobile operator and ask if there are related services that can help you block short messages at specific numbers.

4. Change the number: If the SMS harassment is very serious, you can also consider changing your mobile phone number. This is an extreme method, but it can effectively avoid unnecessary harassment.
