How to prevent fraudulent telephone harassment?

I've never been harassed by fraudulent phone calls, because I don't usually answer strange calls.

1. If fraudulent calls come in frequently, you can always find the call on your mobile phone, and refuse it when it is a number. Set your harassing phone number in the list of rejected calls, so that harassing calls cannot come in.

2. Set up a firewall for incoming calls. Nowadays, smartphones can download a firewall to answer incoming calls. There is a blacklist in the firewall, which is similar to refusing calls. Just like the blacklist in QQ, set the number that often makes harassing calls as a blacklist, or set the answering mode on the firewall to only answer business cards, so that strange numbers outside the business card folder can't be called in.

3. For people who often make harassing calls, you can fight harassment by setting regular short messages on your mobile phone when you are free. The best anti-harassment time is between 2 am and 6 am.

4. Pay attention to protect your information. There are many promotions outside now. Sometimes it is easy to meet shopping malls or individuals engaged in promotional activities when shopping. You will be asked to leave your number then. At this time, you need to protect your number information.

Other methods:

1, take photos, leave messages, call records and other ways to collect evidence of harassing calls.

2. With the support of the police, go to the telecommunications bureau or mobile company to find users who harass the phone number.

3. Collect evidence of health damage caused by harassing phone calls, so as to prosecute those who make harassing phone calls.
