Protect Your SIM Card With the SIM Lock
Password
You can protect your SIM card against unauthorized use with a
personal identification number (PIN). After a PIN is enabled to lock
your SIM, you will need to enter the PIN each time you turn on the
smartphone in order to unlock your SIM.
NOTE: The SIM card will be permanently locked if you enter an incorrect
PIN in three consecutive attempts. You must then enter the Personal
Unblocking Key (PUK) to unlock the SIM card. Please contact your
service provider to obtain the PUK.
NOTE: You can make emergency calls without unlocking the SIM.
