SIM cards usually require a PIN (Personal Identification Number) to unlock your phone so that you can connect to mobile data, make calls and use the internet. They also prevent unauthorized people from using your phone in a situation where your phone is stolen or lost.
Samsung smartphones allow you to protect your personal information by locking your SIM card with a PIN. You always have the option to change your SIM PIN, but you should choose your PIN with care. Some smartphone models come with this option on by default, while others need to have the feature enabled.
With all that said, here’s how to change SIM PIN on Samsung phones.

For this process to be successful, you need to know your current PIN. To do this:
Open your App Drawer and select Settings. On the settings page, scroll down and tap on Biometrics and Security.
Select Other Security Settings.
On the other settings page, tap on Set up SIM card lock. Once here, select Change SIM card PIN. Type in your current PIN when prompted, then type in the new PIN and tap on OK. You will see a notification “SIM PIN changed successfully”.
That’s how to go about it. When you restart your phone, you will be required to type in the new PIN. Hope this helps. Let me know in the comment section below if you have questions.
