Phone Calls 46
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 using 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 using the state
Telecommunications Relay Service (TRS) by first dialing . Then provide the
state TRS with this number: 866-727-4889.

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
TTY equipment or 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.
