In a reasonably more popular move than this one, the FCC have announced that people will not be able to send texts, videos and photos to 911 in the event of an emergency. The service is live right now across four networks, these being AT&T, Sprint, Verizon and T-Mobile, but only in select counties within a handful of states. These include Colorado, Georgia, Illinois, Indiana, Iowa, Maine, Maryland, Montana, New York, North Carolina, Ohio, Pennsylvania, South Carolina, Texas, Vermont, and Virginia. While the service is limited for now, the FCC have said that the service will be available throughout the entire country by the end of 2014.
All the service requires is a text to 911 with your emergency and location. Since texts cannot be tracked, the inclusion of an address within the body of text is imperative to the service. Since this is more or less a beta test at the moment, the FCC has recommended not relying on text to reach 911 unless absolutely necessary.
