For more information about using the headset, see the documentation that came with your headset. 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.
