Using TTY
A TTY (also known as 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 smartphone is compatible with select
TTY devices. You can connect a TTY/TDD
machine to your smartphone through the
headset jack, but you cannot use your
headset jack with a headset 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.
To use TTY, you may need to make
additional arrangements with your wireless
service provider. Please contact your
wireless service provider's customer
service department for more information.
