I just got a call. What should we do?

The handling of this situation is very simple. Now that you have answered this call, it will be OK if you hang up. It needs 1 dime! As far as the current mobile communication technology is concerned, the charging program is located at the outgoing party, so it is impossible to charge when answering the phone. So if there is a call, just answer it, and the other party will spend money! As long as you don't call back and touch any dialing keys, you will be safe. That's how I handled it. If you receive a harassing or fraudulent phone call from the other party, even if you don't talk, the other party will hang up within 60 seconds, because he needs to pay! International calls are more expensive! High school physics teacher wishes you happiness!
