NOTE: This section applies to WWAN devices only.
Make a phone call from the Phone app, the Contacts app, or other apps or widgets that display contact
information.
Emergency Calling
The service provider programs one or more emergency phone numbers, such as 911 or 999, that the user
can call under any circumstances, even when the phone is locked, a SIM card is not inserted or the phone
is not activated. The service provider can program additional emergency numbers into the SIM card.
However, the SIM card must be inserted in the device in order to use the numbers stored on it. See the
service provider for additional information.
Emergency numbers vary by country. The phone’s pre-programmed emergency number(s) may not work
in all locations, and sometimes an emergency call cannot be placed due to network, environmental, or
interference issues.
Audio Modes
The device offers three audio modes for use during phone calls.
• Handset Mode - Switch audio to the receiver at the top front of the device to use the device as a
handset. This is the default mode.
• Speaker Mode - Use the device as a speakerphone.
• Headset Mode - Connect a Bluetooth or wired headset to automatically switch audio to the headset.
Bluetooth Headset
Use a Bluetooth headset for audio communication when using an audio-enabled app. See Bluetooth on
page 100 for information on connecting a Bluetooth headset to the device. Set the volume appropriately
before putting on the headset. When a Bluetooth headset is connected, the speakerphone is muted.
Wired Headset
Use a wired headset and audio adapter for audio communication when using an audio-enabled app. Set
the volume appropriately before putting on the headset. When a wired headset is connected, the
speakerphone is muted.
