How do I reset my device password if I forget it?
For security reasons, the only way that you can reset your BlackBerry device password without knowing your current device
password is to delete all of your device data. You can typically do this by entering an incorrect device password ten times.
If you have the BlackBerry Protect anti-theft feature turned on, to set up your device again, you will need to enter your
BlackBerry ID.
BlackBerry recommends that you regularly create and save a backup file on your computer.
Display text when your device is locked
You can display text on the screen of your BlackBerry device when the device is locked. For example, you can display a
favorite quote, emergency contact information, or your own contact information so that if you lose your device, anyone who
finds it can contact you.

Protect your SIM card with a PIN
You can use a SIM card PIN to prevent unauthorized use of your SIM card in another device. For example, if you lose your
SIM card and someone tries to use it in another device, the SIM card can't be used unless the PIN is entered correctly.
You can request the PIN for your SIM card from your service provider.
