How to deal with people who don't answer the phone

Under normal circumstances, excluding the factors that others deliberately don't want to answer the phone and blacklist your number, the second is that the mobile phone has no signal or is turned off. If the other party doesn't answer the phone all the time, you can send a text message to explain that you have something important, and wait for a call to come back and put yourself in the other's shoes. We can turn on a voice message function on the mobile phone, so that you don't have to get angry when the phone is disconnected.
