8.1.4. Set up a SIM card lock
For better security, you can set up a SIM card lock. The SIM lock will make sure that
only those who know the password can use the phone.
Set up a SIM card lock. Go to [Settings] > [Additional Settings] > [Device &
Privacy] > [Set up SIM card lock]. Click the slider next to Lock Sim Card, type in the
PIN code and then click OK.
Note: If the wrong PIN is entered more than three times, both your SIM card and
phone will be locked. You can enter the PUK code to unlock them. See About SIM
