WARNING: 911 Emergency Calling

Boost Mobile 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.
Tip: You can adjust the ringtone volume in standby mode (or
the earpiece volume during a call) by using the volume
button on the left side of your device.
