Lock SIM card

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 cellular 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.

CautionIf you enter an incorrect PIN multiple times, the SIM will be disabled.

Set up SIM lock

  1. Be sure you have the PIN your carrier provided with the SIM card. If you don’t have it, contact your carrier.

  2. Do one of the following:

    • If your phone allows one SIM card, go to Settings > Security > Set up SIM card lock.
    • If your phone allows dual SIM cards, go to Settings > SIM cards and touch the SIM to change.
  3. Touch SIM card lock or Lock SIM card and turn it on.
  4. Enter your carrier-provided PIN and follow the onscreen instructions.

Unlock SIM card

When prompted, enter the PIN used to set up the SIM lock.

If your phone has two SIM cards and you set up SIM card locks for both, you must unlock SIM1 before SIM2.

If you accidentally disable your SIM

If you enter an incorrect PIN multiple times, the SIM will be disabled.

Contact your carrier for a PIN unlock key (PUK) to re-enable the SIM.
