Some features are not available on my device
Depending on your wireless service plan or the type of email account that is associated with your BlackBerry® device, some features might
not be available on your device.
If your device is associated with an email account that uses a BlackBerry Enterprise Server, your organization might not have set up some
features or might prevent you from using some features or options. If a system administrator has set an option for you, a red lock indicator
appears beside the option field.
For more information about the features that are available on your device, contact your system administrator or wireless service provider.
Phone troubleshooting
I cannot make or receive calls
Try performing the following actions:
Verify that your BlackBerry® device is connected to the wireless network.
If you cannot make calls and fixed dialing is turned on, verify that the phone number for your contact appears in your fixed dialing
list or turn off fixed dialing.
If you have traveled to another country and you have not changed your smart-dialing options, dial the full phone number, including
the country code and area code, for your contact.
If you are not receiving calls, verify that call blocking and call forwarding are turned off.
If your SIM card supports more than one phone number, but you have only one phone number, verify that the phone number is set
as the primary number.
My phone number appears as Unknown in the phone
Try changing the phone number on your SIM card to change how your phone number appears in the phone. In the device options, click
Advanced Options. Click SIM Card. Press the Menu key. Click Edit SIM Phone Number. Type your phone number. Click the trackball.
Note: If you change the phone number on your SIM card, you do not change the phone number that your BlackBerry® device uses to
make and receive calls.
