i don’t want rtt/tty on my phone how do i turn it off

To disable it, tap on Settings > Accessibility > RTT/TTY, and then, turn off both the "Software RTT/TTY" & "Hardware TTY" options.

Then try the following:

• Reset your phone's network settings: Tap on Settings > General > Reset > Reset Network Settings
• If that doesn't help, then try the "Reset All Settings" option.

You're welcome!

Settings, accessibility, RTT/TTY, turn off there.
