How to prevent numbers starting with 00 from coming in?

With the development of communication technology, our life depends more and more on mobile phones, but there are more and more harassing calls, especially those international long-distance numbers starting with 00. How to effectively prevent these harassing calls from coming in has become the focus of attention. Here are some effective methods:

Method 1: Use the blacklist function that comes with the mobile phone.

Now most mobile phones have a blacklist function, which can add the number of harassing calls to the blacklist, so that when the number in the blacklist comes in, the mobile phone will automatically intercept it. If your mobile phone doesn't have its own blacklist function, you can download some third-party blacklist software in the app store, such as "360 Security Guard" and "Panda Guard".

Method 2: Use the service provided by the operator.

Some operators provide harassing phone interception service, and users can apply for opening the service by calling the operator's customer service phone. After opening, users can add harassing phone numbers to the blacklist, and when these numbers come in, they will be intercepted. It should be noted that this service may incur a certain fee.

Method 3: Use third-party interception software.

In addition to the blacklist function of mobile phones and the services provided by operators, there are also some third-party interception software, such as "Cat's Eye Seeing the World" and "Call Show". These softwares can automatically identify harassing calls and intercept them. However, it should be noted that when using third-party software, we must ensure the security of the software and avoid downloading malicious software.
