Why are there calls from overseas?

There are several situations:

1. The other party uses disguise software when calling, causing the phone to display as an overseas call. This kind of call is usually a scam call, so it's best not to answer it.

2. Criminals’ fraudulent calls. Criminals generally commit crimes in other places, commit fraud in other places, and withdraw money from different banks in other places. If they defraud citizens, they usually make calls from other places, or use mobile phones from other places to make local calls. Criminals mostly come from the same area and have a strong sense of "protecting" each other.

3. International friends dialed the wrong number and called by mistake. (When you hear a foreign language, you may have dialed by mistake. When you call back, the number is empty. It may be that international long distance is not activated.)
