Enhanced 911, or E911, is a service that allows emergency operators to provide better assistance to people calling 911 from their mobile phones. E911 can provide emergency operators with improved location information, which can be used to direct emergency service personnel more precisely to people calling 911 from their mobile phones.
- Enhanced 911, or E911 Phase 1, is a service that displays your mobile phone number to emergency operators as well as the location of the cellular site carrying your call.
- E911 Phase 2 provides improved location information. E911 calls from mobile phones are subject to the same limitations as regular calls from mobile phones. For example, if you’re underground or too far from a network antenna, your signal quality may be affected and you may not be able to connect to the network.
