About using a headset
You can purchase an optional headset to use with your BlackBerry smartphone.
If you use a headset, you can use a headset button to answer or end a call, or to turn on or turn off mute during a
call. Depending on your smartphone model, you might be able to use a headset button to make a call using a voice
command.
Depending on your headset, you might also be able to use a headset button to pause, resume, skip, or adjust the
volume of audio or video files.
For more information about using the headset, see the documentation that came with your headset.
Emergency calls
About emergency calls and Emergency Callback Mode
If you're outside of a wireless coverage area and the indicator appears at the top of the screen, you can call
only emergency numbers. Your BlackBerry smartphone is designed to allow emergency calls even when your
smartphone is locked. Depending on your smartphone model and the wireless network that your smartphone is
connected to, your smartphone is also designed to allow emergency calls when the SIM card isn't inserted. If the
connection to the wireless network is turned off when you initiate an emergency call, your smartphone 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 smartphone 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 smartphone is connected to a CDMA network, when you end an emergency call, your smartphone 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 can't send and receive messages or browse webpages.
If your smartphone supports GPS and you make an emergency call, an emergency operator might be able to use
GPS technology to find your approximate location.
