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.
Note
In TTY Mode, your device will display the TTY access
icon.
If TTY mode is enabled, the audio quality of non-TTY
devices connected to the headset jack may be
impaired.
