A TTY (also known as a TDD or Text Telephone) is a
telecommunications device that allows people who are
deaf, hard of hearing, or who have speech or language
disabilities, to communicate by telephone.
Your phone is compatible with select TTY devices. A TTY device
will activate TTY mode on the phone when it is properly
connected. Please check with the manufacturer of your TTY
device to ensure that it supports digital wireless transmission.
Your phone and TTY device will connect via a special cable
that plugs into your phone's headset jack. If this cable was
not provided with your TTY device, contact your TTY device
manufacturer to purchase the connector cable.
When establishing your wireless service, please call your
service provider via the state Telecommunications Relay
Service (TRS) by first dialing
. Then provide
the state TRS with this number: 866-727-4889.
In TTY Mode, your phone will display the TTY access icon.
If TTY mode is enabled, the audio quality of non-TTY devices
connected to the headset jack may be impaired.
911 Emergency Calling
It is recommended that TTY users make
emergency calls by other means, including
Telecommunications Relay Services (TRS), analog
cellular, and landline communications. Wireless
TTY calls made to 911 may be corrupted when
received by public safety answering points (PSAPs)
rendering some communications unintelligible.
The problem encountered appears related to TTY
equipment or software used by PSAPs. This matter
has been brought to the attention of the FCC,
and the wireless industry and PSAP community
are currently working to resolve this.
