Google is using your Android phone to make it easier for emergency services to find you when you need help. With support from mobile networks, the Emergency Location Service sends your location of your phone to emergency services when you call an emergency number.
This feature, when supported by your network, sends location from your phone to emergency services when you dial an emergency number. This uses the same location technologies available to apps on your phone, including Wi-Fi, GPS, and cell towers, to produce a more reliable emergency location both indoors and outdoors.
Your location is only sent to emergency services, and is never seen by Google, nor sent through their servers. The Emergency Location Service will be available as a part of Google Play Services for phones running Android 2.3 Gingerbread or later, which Google says covers around 99% of Android phones.
Emergency Location Service is already live in the UK and Estonia through carriers like BT, EE, Vodafone, O2, Tele2, and Telia. Google is working with other countries and carriers in order to facilitate an faster international rollout of the feature.
