How can I not answer anyone's phone or receive information?

You can turn on the switch that intercepts all calls and all short messages in your mobile phone.

Take Huawei's mobile phone operation as an example:

1. First, open the phone, find the mobile phone housekeeper on the phone, and click Enter.

2. Enter the phone housekeeper interface, and click the harassment interception.

3. Then enter the harassment interception interface and select the following interception rules.

4. Select the phone interception rules and SMS interception rules under the interception rules to enter.

5. Turn on the switch to the right of intercepting all incoming calls and intercepting all strangers in the telephone interception rules.

6. Turn on the switch of all strangers in the SMS blocking rules, and you can't receive other people's mobile phones and SMS after setting.
