Hello, landlord, I'm glad to answer your question. This is the case with Apple 6plus (excluding human factors). It should be in the setting place, and the landlord did not open it (iMessage), so it is impossible to display and send it. Please follow my steps to set it up.

1: Please open the settings on the home screen first, and then open the following programs in turn.

2: Please open the information.

3: Please open iMessage.

4: Please open and send the read receipt.

5: Please open it and send it by SMS.

6: Please turn on sending and receiving MMS.

7: Please open the display subject bar.

8: Please turn on character counting.

9: Return to the settings page, please turn on privacy.

10: Then start the location service.

1 1: Please close Apple 6plus. After 3 minutes, please turn on the phone and restart it.

12: Turn on the flight mode after restart, and then turn it off.
