Change your SIM PIN code

If your SIM card came with a pre-set PIN code, you can change it to something more secure. Not all network service providers support this.

Select your SIM PIN

You can choose which digits to use for the SIM PIN. The SIM PIN code can be 4-8 digits.

  1. Tap Settings > Security > SIM card lock.
  2. Under the selected SIM card, tap Change SIM PIN.
Tip: If you don’t want to protect your SIM with a PIN code, switch Lock SIM card to Off, and type in your current PIN.
