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, 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
