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.
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. Click the trackwheel. Click Edit SIM Phone Number. Type your phone number. Click the
trackwheel.
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.
