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.
