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.
Caution
Do not turn on the Hearing Aid Compatibility setting unless you use a
hearing aid with a telecoil. Using this setting without a hearing aid or with a
hearing aid without a telecoil may be harmful to your hearing.
