BlackBerry关于emergency calls and Emergency Callback Mode

About emergency calls and Emergency Callback Mode

If you are outside of a wireless coverage area and the SOS wireless coverage indicator appears at the top of the screen, you can call only emergency numbers. Your BlackBerry® device is designed to allow emergency calls even when your device is locked. Depending on your device model and the wireless network that your device is connected to, your device is also designed to allow emergency calls when the SIM card is not inserted. If the connection to the wireless network is turned off when you 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.

If your device is connected to a CDMA network, when you end an emergency call, your device enters Emergency Callback 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.
