TTY Use With Sprint 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 device is compatible with select TTY devices. You can connect a TTY/TDD machine,
headset, or hands-free kit to your device through the headset jack while this mode is
enabled. Please check with the manufacturer of your TTY device for connectivity
information and to ensure that the TTY device supports digital wireless transmission.
When establishing your Sprint service, please call Sprint Customer Service via the state
Telecommunications Relay Service (TRS) by first pressing 711 and then pressing Talk .
Then provide the state TRS with this number: 866-727-4889.
WARNING: 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
it.
