How do mobile phones intercept spam messages?

If you use a vivo phone, you can block harassing messages by turning on harassment interception.

Harassment interception setting method:

1. Enter Settings-(Application and Permission)-(System Application Settings)-Information-Information Interception-Open the corresponding interception option;

2. Enter I Housekeeper-Utility-Harassment Interception-Information Interception-Open the corresponding interception option;

If you often receive spam messages with the same number, you can add the number to the blacklist for interception.

How to set a blacklist:

Enter the call record-long press a number-to join the blacklist.

You can also go to I Housekeeper-Utilities-Harassment Interception-Blacklist-click the "+"icon-you can check it or manually enter Add.

After the contact is blacklisted, if the contact makes a call, there will be a prompt "The subscriber you dialed is busy, please redial later".

When a contact is blacklisted, calls and text messages from that contact will be blocked.
