what is TTY on iPhone

1 Answer from the Community

  • TTY = Teletypewriter or Teletype machine.

    Teletype (TTY) machines are used by deaf and hard of hearing people to communicate by typing and reading text. If you have the iPhone TTY Adapter, available at Apple online store, you can use iPhone with a TTY machine.

    See the Apple knowledge base (kb) article "HT3519" for further details.
