How to display voice in the text editing bar of Apple mobile phone, but not text?

1, confirm that the signal is normal and close the flight mode.

2. Check whether the SIM card status is normal.

3. Check whether the send key is displayed in bright color and clickable.

4. If you can't click Send after entering the text, the "Send" key is still gray. Please turn off the "Show Subject Bar" in the setup SMS.

5. If you send text messages to multiple people and manually enter numbers, please make sure to use line breaks instead of spaces to separate each number.
