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, 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 is compatible with digital wireless 
phones. 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 service, please call 
Sprint Customer Service via the state 
Telecommunications Relay Service (TRS) by first 
dialing 
where the phone
number now appears.
For additional technical support you may call

WARNING
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 software used 
by PSAPs. This matter has been brought to 
the attention of the FCC, and the wireless 
industry and the PSAP community are 
currently working to resolve this.
