If you want to make a message on your iPhone unread, there are a few ways to do it. The first way is to go to the Messages app and select the message you want to delete. Then, tap the three lines in the top left corner of the screen and select “Delete Message.” The second way is to go to your iPhone’s Settings app and scroll down until you see “Mail, Contacts, Calendars.” Tap it and then tap “Message Alerts.” From here, you can turn off all of the alerts for this particular message by turning off the checkbox next to it. The last way is to go into your iPhone’s Settings app and scroll down until you see “General.” Under “Privacy,” tap on “Message & Data Usage.” Here, you can disable all notifications for this particular message by turning off the checkbox next to it. ..
