A TTY (teletypewriter) is a keyboard-like device that allows deaf, hard of hearing, and other people with speech impairments to place calls to standard telephone users. TTYs can be connected to any type of real-time text capable technology, such as a personal computer, laptop, mobile phone, PDA, and many other devices.

TTY calls are typically the most common type of TRS (Telecom Relay Service) call. TTY calls are usually answered by a TELUS Relay agent who relays the message to a hearing person over the phone.

The TELUS Relay service is available 24 hours a day, 7 days a week, free of charge for local calls. Applicable long distance and directory assistance charges apply. TELUS Relay agents are professionally trained and follow a code of ethics.
