TTY Use With Sprint Service
A TTY (teletypewriter, 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.
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
Sprint via the state Telecommunications Relay Service
(TRS) by first dialing
. Then provide
the state TRS with this number: 866-727-4889 .

Note In TTY Mode, your phone will display the TTY access
icon when a headset or TTY device is plugged in.
If TTY mode is enabled, the audio quality of non-TTY

WARNING 911 Emergency Calling
Sprint recommends that TTY users make
emergency calls by other means, including
Telecommunications Relay Services (TRS),
analog cellular, and landline communications.
Wireless TTY calls 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.
