NOTICE:
911 Emergency Calling
Sprint recommends that TTY users make emergency
calls by other means, including Telecommunications
Relay Services (TRS), analog cellular, and land line
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.
