Send a message to the little moon to inform silence.

What does the moon mean in Apple SMS? "There is a moon in front of Apple's SMS, which means that the anti-jamming function in the message is turned on, which means that this SMS notification is hidden. If you send another short message with the same number, the notification bar will not display the notification reminder of receiving this short message. When you swipe a message to the left, the Hide Reminder option appears. If you click this option, the message from the current contact will be muted, and there will be no notification reminder, which can only be viewed when you open the Messages application. If you want to restore the reminder, you can swipe the message to the left again and click Show Reminder to restore the information notification. " ?
