and even the money in your bank account could be at risk. SIM lock requires a PIN to be
entered each time your device is powered on or connected to another device. This prevents
others from using your SIM card and gaining access to your finances or private information.
Before performing the above operations, please obtain your SIM card PIN from your carrier.
Use a PIN to lock your SIM card: Open Settings. Go to Security & privacy > More and
touch set SIM1/SIM2 LOCK to enter the SIM lock settings screen. Enable SIM Lock, enter your
PIN, and touch OK.
Change your SIM card's PIN: Set a new PIN to make sure your PIN stays secure. After
unlocking your SIM card, touch Change SIM PIN and follow the instructions to set a new PIN.
l If you enter an incorrect PIN more than the allowed number of times, you will have to
enter a PUK code to unlock your SIM. If you forget your PUK code, please immediately
request the correct PUK code from your carrier. If this code is entered incorrectly too
many times, it may void the SIM card.
l There is a limit to the number of times a PIN or PUK code can be entered. Please contact
your carrier if you need assistance.
