Is there a mistake in the short message?

There will be mistakes, one of which is delay, which is not the most troublesome. There is also packet loss, which means that the information is completely lost. There is another kind, that is, text messages are sent to someone else's mobile phone number by mistake. This kind of situation is rare, and four mobile phones will happen at the same time. That is to say, two pairs of mobile phones that originally sent text messages to each other inexplicably received messages from another team, and their own messages were also sent to two other people. I have used my mobile phone for so many years, and this situation is one.
