Using a Bluetooth device for calls

Bluetooth device with iPhone” on page 33.

Emergency calls
If iPhone is locked with a passcode, you may still be able to make an emergency call.

Call, then enter the emergency number and tap the green button.
In the U.S., location information (if available) is provided to emergency service providers when
you dial 911.
With CDMA, when an emergency call ends, iPhone enters Emergency call mode to allow a call back
from emergency services. While in this mode, data transmission and text messages are blocked.
