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.
