If you're deaf or in an emergency where you can't speak, getting a hold of 911 is problematic. In just a few hours, the nation's leading mobile providers will start the support of texting to 911 for emergencies in certain areas.
The providers supporting the service include AT&T, Sprint, T-Mobile and Verizon Wireless. For the time being, only certain states and counties have call centers that support 911 texting, but the goal is to get this service rolled out nationwide as soon as possible. If you're located in an area that will allow the service, make sure you provide your location when texting 911. Call centers will not have the ability to triangulate your location the same way they can with a phone call.
