The time to send text messages to mobile phones has changed. Will the business hall time change?

There are several reasons why the SMS time will change: 1 Sometimes, the SMS time will be affected by the wrong setting of the mobile phone of the person who sent you the SMS, but this is rare. I have received a short message from my classmates in other provinces three days ago because it is 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 has problems. When you send it, you will find that you have not received it at all. After being fixed by the mobile operator, you will also find that you received a short message at the wrong time.
