Can you see the message before the six messages are out of sync?

I do not see any at all. You can't switch mobile phone messages without synchronization, but you can still see them without changing your mobile phone. Message information is unsynchronized, that is, messages received locally are not synchronized to the cloud server. Because the time set by the person who sent you the text message is wrong, it sometimes affects the time of the text message. However, this situation is less because of cross-provincial SMS or maybe because of the signal problem of mobile operators, especially at the end of the month and the beginning of the month.
