initiate an emergency call, your device is designed to connect to the wireless network automatically. You can make emergency
calls by typing only official emergency access numbers (for example, 911 or 112).
Note: You should not rely on any wireless device for essential communications, including medical emergencies. Emergency
numbers may vary by location and emergency calls may be blocked or impeded by network, environmental, or interference
issues.

Mode. This mode allows the operator to call you back or find your approximate location. Depending on your wireless service
provider, Emergency Callback Mode is active for 5 minutes or until you make a non-emergency call. In Emergency Callback
Mode, you cannot send and receive messages or browse web pages.
If your device supports GPS and you make an emergency call, an emergency operator might be able to use GPS technology to
find your approximate location.
