  • TTY is an abbreviation for teletypewriter, also known as a text telephone or a telecommunication device for the deaf (TDD). This device allows people who are deaf, speech impaired or hard of hearing to type messages to anyone else who has a TTY, using a telephone line.
  • Some phones might not support Telecoil and TTY/TDD.
