How to keep mobile phones from generating spam messages?

If you use a vivo phone, you can refer to the harassment interception setting method:

1. Go to Settings-(Application and Permission)-(System Application Settings)-Phone/Information-Harassing Phone/Information Interception-Open the corresponding interception option;

2. Enter I Housekeeper-Utility-Harassment Interception-Telephone Interception/Information Interception-Open the corresponding interception options;

3. Some models have no harassment interception, so you can enter Settings-Set Blacklist in your mobile phone.

If you have more questions, you can go to official website /vivo Mall APP-My-Online Customer Service or vivo official website Web Edition-Slide to the End-Online Customer Service-Enter the manual customer service for consultation and understanding.
