IMPORTANT NOTICE:
911 Emergency Calling
Sprint recommends that TTY users make emergency calls by other means,
including Telecommunications Relay Services (TRS), 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 PSAP community are currently
working to resolve this.
