Apple's 5s short message, will it show delivered and read?

1. When Apple 5s sends a text message, it will show that it has been sent, but it will not show whether it has been read.

2. When sending a short message, there will be a progress bar at the top of the short message interface. When the progress bar goes from left to right and then ends, it will show that it has been sent. At this time, the SMS display has been sent.

3. It will not show whether it has been read, because the SMS that comes with the system cannot detect whether the other party's mobile phone is open for SMS reading. Some online chat software will have the function of prompting whether it has been read.
