There are people who just won’t use a PIN code on their SIM card. Maybe you’re one of those users, or maybe you just want to change your SIM card’s PIN code. Either way, we’ve got you covered.

In the Settings menu, choose Security, then Set up SIM card lock.
First, here’s how to disable the SIM card PIN. All you have to do is to uncheck the box next to Lock SIM card, and then confirm the change by inputting the current PIN code. That’s it!

There you go! You’ve just changed your SIM PIN code.
