Unlock your device with a network unlock code
To obtain the unlock codes for your BlackBerry device, contact your service provider.
Your device might be network locked which allows your device to make a mobile network connection with only your current
service provider. If you plan to travel internationally and you want to use a SIM card from another service provider, you
might need to enter an unlock code.
Tip: To see the current service provider associated with your device, on the home screen, swipe down from the top of the
screen. Tap Settings > About. In the Category drop-down list, tap SIM Card.
1. On the home screen, swipe down from the top of the screen.
2.
Tap Settings > Security and Privacy > SIM Card.
3. In the Phone Network Lock section, tap a locked item.
4. When prompted, enter the unlock code.
CAUTION: For security reasons, each unlock code can only be entered incorrectly 10 times. If you exceed the number of
allowed attempts to enter an unlock code, your SIM card will allow emergency calls only. For assistance, contact your
service provider.
Change or remove your device password
CAUTION
: If you can't remember the password for your BlackBerry device, the only way to change your password or regain
access to your device is to delete all of your data by completing a security wipe.

be able to remove the password for your device.

How do I reset my device password if I forget it?
Your BlackBerry device password can't be recovered or changed if you don't enter your current password correctly. For
security reasons, the only way that you can reset your password without knowing your current password is to delete all of
your device data. You can do this by entering an incorrect device password multiple times.
BlackBerry recommends that you regularly create and save a backup file on your computer.
