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 device is compatible with select TTY devices. Please check with the manufacturer of your TTY device to ensure that it supports digital wireless transmission. Your device and TTY device will connect using a special cable that plugs into your device’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 service, please call Sprint Customer Service using 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 > and tap Settings > Call settings > Enable TTY support.

2.Tap Full mode, VCO mode, or HCO mode to turn TTY mode on.

– or –

Tap Off to turn TTY mode off.

Note	When enabled, TTY mode may impair the audio quality of non-TTY devices connected to the headset jack.
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
		the PSAP community are currently working to resolve this.
