TTY Use With Sprint PCS Service

A TTY (also known as a TDD or Text Telephone), is a telecom- munications 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.

1.Press . (A brief explanation of TTY Mode will display.)

2.Press to continue.

3.Press key up or down to select Enable TTY or Disable TTY and press .

Note: In TTY Mode when your headset is plugged in, your phone will display the TTY access icon.

IMPORTANT NOTICE:

911 Emergency Calling

Sprint recommends that TTY users make emergency calls by other means, including Telecommunications Relay Services (TRS), analog cellular, and land line 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.
