TTY Use With Sprint PCS Service
A TTY (also known as a TDD or Text Telephone) is a telecommunications
device that allows people who are deaf or 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 Sprint PCS Service, please call Sprint Customer
Service via the state Telecommunications Relay Service (TRS) by first
dialing . Then provide the state TRS with this
number: 866-727-4889.
To turn TTY mode on or off:
1. Press to access the main menu.
2. Select Settings and press .
3. Select Others and press .
4. Select TTY and press . (You will see a message on the display.)
5. Press or OK (left softkey) to continue.
6. Select Enable or Disable and press .
Note:When you connect TTY devices, your phone will display the icon in TTY mode. If
TTY mode is enabled, the audio quality of non-TTY devices connected to the headset jack
may be impaired.
IMPORTANT NOTICE: 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.
