About SIM card security
Use SIM card security to add another level of security to your device. This level of security is designed to prevent unauthorized use of your
BlackBerry® device or SIM card by locking the SIM card with a PIN code. If you lock your SIM card, other people cannot remove your SIM
card and insert their own and they cannot remove your SIM card and insert it into another device.
If you have protected your SIM card with a PIN code, you must type the PIN code before you can remove your SIM card and insert it into
another device.
