IMPORTANT 
NOTICE:
911 Emergency Calling
It is recommended that TTY users make emergency 
calls by other means, including Telecommunications 
Relay Services (TRS), analog cellular, and land line 
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.
