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 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.
