Knowing what time messages were sent and received
The default settings on your iPhone don’t allow you to see the timestamp for sent or received messages. Instead, all you get are the day and time of the first message of a conversation. If you want to see the timestamp of every message, there’s not a lot you have to do.

First, open up the Messages and open up any conversation. To see the timestamp of every message, slide your finger from left to right. You’ll immediately see what time messages were sent and received. You might have to do this every time you open up Messenger, but it’s a minor inconvenience at most.
