If your SIM card came with a default SIM PIN code, you can change it to something more secure. Not all network service providers support this.
You can choose which digits to use for the SIM PIN. The SIM PIN code can be 4-8 digits.
Tip: If you don’t want to protect your SIM with a PIN code, in Set up SIM card lock, switch Lock SIM card to Off, and type in your current PIN.
