It turns out Indiana is one of the nation's leaders when it comes to texting 911 for emergency help. All but four of Indiana's 92 counties have signed on to a system that allows cellphone users to text 911. Lake, Jasper, Marion and Ripley counties are the holdouts. Only the states of Vermont and Maine have ALL counties accepting text messages to 911. Fifteen others have a few counties each that participate in the “Text to 911” system. A federal order required ALL wireless carriers and text-messaging providers to allow users to send texts to 911 dispatchers by the end of last year.
