If the SMS is out of sync, can I receive the message?

I can't. You can't receive information without synchronization of SMS, because the synchronization function of SMS is mainly to prevent users from losing SMS when changing their mobile phones or restoring their mobile phone data. Through the synchronization function, users can back up the short messages in their mobile phones to the network server, and then restore them to their new phones when necessary, thus ensuring that they will not lose short messages because of changing their mobile phones or restoring their mobile phone data, and they will not be able to receive information without synchronization.
