Why Change Your SIM Card PIN?

Your SIM card’s PIN acts as a password to prevent unauthorized use of your cellular plan if your iPhone is lost or stolen.

But most carriers set a default PIN that is easy to find online, like 1234 or 0000. That makes it less secure.

By changing the SIM PIN to a custom code, you can better protect your iPhone cellular plan and prevent misuse.
