How to block calls from Taiwan?

For mobile phones, dial 10086 (10010 for China Unicom and 10000 for China Telecom) to switch to manual and activate free interception. At the same time, the mobile company will send each intercepted call to the owner in the form of a text message. This is very good. It intercepts harassing calls and overseas calls, and the same applies to China Unicom and China Telecom.

In daily life, due to the leakage of information due to business transactions or certain reasons, we often receive various harassing phone calls.

The purpose of harassing calls is to make money through fraud. Through extensive phone calls, many people can realize that it is a scam, but there are still a few people who will be deceived, follow the prompts of the harassing phone calls, and disclose their money or personal information to others.
