What is the difference between 911 and E911 service?

Basic 911 service simply connects the caller to a local Public Safety Answering Point (PSAP). Although the call is connected to a dispatcher, the dispatcher may not have all of the caller's information such as name or address. Enhanced 911 (E911) provides a data stream along with the call so that when a customer is connected to a PSAP, the dispatcher has the caller's name and address for faster response. Similar to major phone companies, WOW! Phone provides our users with E911 service.
