How to set the phone blacklist?

If you use a vivo phone, just enter the phone/contact-long press a number-(more)-and join the blacklist.

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

When you add a contact to the blacklist, calls and text messages from this contact will be blocked.

Note: You can view it in I Housekeeper-Harassment Interception-Blacklist, and you can cancel the blacklist number as long as you need it. Click Delete to cancel the blacklist.
