choose to close iMessage, so as to avoid privacy exposure. Need to remind everyone that when you send ordinary information, the background of the information is green. When you enter a short message, the "Send" button is usually green, but when you and the other party open iMessage, the button will automatically turn blue within a few seconds. In other words, it will take a few seconds to automatically detect whether the other party can use iMessage. At this time, the message you send will also become a blue background box.
