How to hack the phone number

If you use a vivo phone, you can refer to the following settings:

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 calls the mobile phone, there will be a prompt "The subscriber you dialed is busy, please redial later".

After adding a contact to the blacklist, incoming calls and text messages sent by the contact to the mobile phone will be blocked.

If you refer to other blacklist settings, you can enter vivo official website-My-Online Customer Service-and enter the online customer service feedback for manual consultation.
