TTY Access With PCS Service 
From Sprint
A TTY (Text Telephone), also known as a TDD (Teletype Device 
for the Deaf), 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 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 Nokia phone is 
equipped with a universal 2.5mm accessory jack that can be 
used to connect the cable of a “cellular ready” or “cellular 
compatible” TTY/TDD device to your phone. If this cable was 
not provided with your TTY device, contact your TTY device 
manufacturer to purchase the connector cable.
When establishing your PCS Service, please call 
PCS Customer Solutions
SM
via the state Telecommunications
Relay Service (TRS) by first dialing
. Then
provide the state TRS with this number: 866-727-4889.
To turn TTY Mode on or off:
1. Connect the TTY/TDD device to your phone.
2. Press Menu, scroll to Settings, and press Select.
3. Scroll to Enhancement settings and press Select.

Note:
If TTY mode is enabled, the audio quality of non-TTY devices
connected to the headset jack may be impaired.
IMPORTANT NOTICE: 911 Emergency Calling
Sprint recommends that TTY users make emergency calls by other means 
including Telecommunications Relay Services (TRS), analog cellular, and 
landline 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 this.
