What is the reason for the wrong message time?

There are many reasons, and I have met them. There are probably the following reasons: 1 Sometimes, the SMS time is affected by the wrong time set by the person who sent you the SMS, but this is rare. I received a short message from a classmate from other provinces three days ago, because it was an inter-provincial short message or because of the signal problem of mobile operators (especially at the end of the month and the beginning of the month). Because the format or content of the short message sent by the other party is too complicated or problematic, it will be found that it was not received when it was sent, and the mobile operator will find that it received the short message at the wrong time after repairing it.
