You can use a text telephone/teletypewriter (TTY) to communicate with anyone and anytime on the phone!  The communications assistant reads aloud the message you typed to the other party and types the other party’s voiced message and background sounds, if any, to you.

This service is designed for people who are Deaf, Hard of Hearing or have a Speech Disability.

This relay service is available in English-to-English and Spanish-to-Spanish.

How Does TTY Relay Work?

It’s simple!

Just dial 711 (800-722-0353 for English or 800-662-4955 for Spanish) on your TTY and a communications assistant will answer with “Oklahoma Relay”.

Type the area code and telephone number you wish to call and type “GA” (“Go Ahead”).  The communications assistant will dial the number and connect you to the other party.

  • 1

    Type your message on the TTY. Type “GA” (“Go Ahead”) at end of each message. The “GA” indicates that it is the other party’s turn to respond.

  • 2

    The communications assistant reads out loud the message you typed to the other party.

  • 3

    The other party listens, then speaks.  When they say, “Go Ahead”, it is your turn to respond. 

  • 4

    The communications assistant types the other party’s voiced message to you.

To conclude the call, type “GA to SK” (“Stop Keying”) to indicate that you are ready to hang up.
