Lock SIM card

Set up SIM lock

Your SIM card came with a default PIN from your carrier. You can use it to set up an optional SIM card lock, which prevents others from using your mobile plan and accessing account information if your phone is stolen.

If you add a SIM lock, you will be prompted to enter the PIN each time you swap SIM cards or restart the phone.

  1. Make sure you have the PIN your carrier provided with the SIM card. If you don't have it, contact your carrier.
  2. Go to Settings > Security > Set up SIM card lock.
  3. If your phone has dual SIM cards, touch the SIM to lock it.
  4. Turn Lock SIM card on .
  5. Enter your carrier-provided PIN and follow the onscreen instructions.
