How to make a mobile phone not receive messages and incoming calls from a number?

1. Your mobile phone must support an incoming call firewall and a short message firewall to reject incoming calls and short messages at this number;

If you don't want to answer his phone, you can answer it and ignore him. Put your mobile phone on the table. Everyone else is talking. It's meaningless if he can't hear your reply.

3. The worse trick is to answer his phone and then whistle into the microphone, and the other party will definitely not be able to stand it;

You can also ask another man to answer the phone when he calls. If he hears every time he answers the phone, he will naturally stop calling.

The second method is the easiest and works well. You can have a try and come back to scold me if you are not satisfied.
