If your BlackBerry smartphone isn’t getting any voice or data service at all, you can try the following to troubleshoot the problem.
- Are you using your smartphone inside a building? If so, the network signal strength may be insufficient.
In the upper right-hand corner of your BlackBerry home screen you’ll see a number of coverage bars indicating signal strength. If you don’t see any coverage bars or if there is an out of service (SOS) icon, then you do not have adequate wireless coverage
Here are a couple of ways to check the network signal strength.
- Make sure your BlackBerry is turned on
- From the Home screen, click the Options icon
- In the Options screen, click Status
- In the Status screen, check the Signal field. The signal strength must be within the -40 to -100 Dbms range to give you adequate wireless coverage
You can also check your wireless signal strength using a keyboard shortcut (on BlackBerry smartphones with full QWERTY keyboards).
- While holding down your BlackBerry's ALT key, type the letters N, M, L, L
- Your home screen will show your wireless signal strength, measured in dbms.
If you don’t have adequate signal strength, try your call from another part of the building or outside.
- Ensure that the Mobile Network is turned on:
- Press the BlackBerry key to the left of the trackball to go to the main menu
- Click on the Manage Connections icon
- Ensure the box marked Mobile Network is checked
- Perform a hard reset of your smartphone. (Note that this will not delete any settings or data on your BlackBerry smartphone.)
- Remove the battery cover and then the battery. You may need the edge of a credit card or other tool to gently pry it out.
- Wait a few moments, then replace the battery and cover. It may take a few minutes for your BlackBerry to restart.
- Ensure you have the latest software upgrade for your BlackBerry smartphone.
- Check our coverage maps to ensure you have coverage.
- Does this only occur when you’re roaming? If so, ensure that your BlackBerry isn’t set to Home only. The Home only setting prevents your smartphone from selecting another carrier when you roam outside the Bell network. Visit the phones and accessories page and select your phone model to see your user guide for information on adjusting this setting. Note: Disabling home only will allow roaming on foreign networks. Roaming charges will apply. Learn more about using your smartphone in the U.S. or using your smartphone overseas.
