Why do mobile phones frequently receive feedback of successful SMS sending?

Mobile phones frequently receive the feedback information of successful SMS sending, mainly because of the opening of the information reporting column. If you don't need this function, you can enter the SMS function menu and set the "Information Report" column to "Off".
