Why did it take a few days to send messages when they blackmailed each other?

It should be that the other party's mobile phone is not normal.

This situation is generally because the other party's mobile phone has no signal or the communication is abnormal, which leads to the information not being sent out and the information is out of date. It is also possible that the other party received your message, but did not open it to read the message you sent. This will also happen.
