Enabling TTY
You can enable your smartphone for use
with a TTY/TDD device. A TTY (also known
as a TDD or Text Telephone) is a
telecommunications device that enables
telephone communication for people who
are deaf or hard of hearing, or who have
speech or language disabilities.
Your smartphone is compatible with select
TTY devices. You can connect a TTY/TDD
machine, headset, or hands-free kit to your
smartphone through the headset jack while
in TTY/TDD mode. Please check with the
manufacturer of your TTY device for
connectivity information. Be sure that the
TTY device supports digital wireless
transmission.
