User Guide Phone Emergency calls About emergency calls If you are outside of a wireless coverage area and the SOS wireless coverage indicator appears, you can only call 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 only make emergency calls by typing 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. About Emergency Callback Mode If your BlackBerry® device is connected to a CDMA network, when you end an emergency call, your device enters Emergency Callback Mode. This mode enables the operator to call you back or determine your approximate location. Depending on your wireless service provider, Emergency Callback Mode is active for five minutes or is canceled when you make a non-emergency call. In Emergency Callback Mode, you cannot send and receive messages or browse web pages. Your device exits Emergency Callback Mode at any time if you make a non-emergency call. Make an emergency call Perform one of the following actions: • If your keyboard or BlackBerry® device is unlocked, from the Home screen, press the Send key. Type the emergency number. Press the Send key. • If your keyboard is locked, type the emergency number. Press the Send key. • If your device is locked, press the Menu key. Click Emergency Call. Click Yes.If your keyboard or device is locked or your device is in standby mode, type the emergency number. Complete the instructions on the screen. About GPS technology Depending on your wireless service provider, this feature might not be supported. You can use GPS technology on your BlackBerry® device to get your GPS location and to use location-based applications and location-based services. Location-based applications can use your GPS location to provide you with information such as driving directions. 27
