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.

has been brought to the attention of the FCC,
and the wireless industry and the PSAP
community are currently working to resolve this.
