wireless network. See the printed documentation that

wireless coverage levels.
Why am I no longer receiving calls?
Verify that you are in a wireless coverage area and 
that your BlackBerry® device is connected to the 
wireless network. See the printed documentation that 
accompanied your device for more information about 
wireless coverage levels.
If you still cannot receive calls, verify that call 
forwarding is turned off.
Can I use the phone when the device 
or keyboard is locked?
The BlackBerry® device is designed to enable you to 
make emergency calls when your device or keyboard is 
locked. 
See “Make emergency calls” on page 11 for more 
information on emergency calls.
If your device is integrated with a corporate email 
account, you might be able to make other phone calls 
when your device is locked. Contact your system 
administrator for more information.
If you receive a call when the keyboard is locked, the 
keyboard unlocks when you answer the call.
If you receive a call when the device is password 
locked, you can answer the call, but your device 
remains password locked during the call. You can 
perform regular phone actions, such as mute and hold. 
When you end the call, the device remains password 
locked.
