IMPORTANT NOTICE: 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 PSAP community are
currently working to resolve this.
