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.
