How to Change SIM Card PIN
Your SIM card PIN is a security feature that helps protect your mobile line from unauthorized use. If you want to update your SIM card’s security or make the PIN easier to remember, you can change it directly from your phone settings. The process is straightforward and works for most mobile networks and smartphones.

What If You Forget Your Current SIM PIN?
If you enter the wrong PIN three times, your SIM will lock, and you’ll need a PUK (Personal Unblocking Key).
The PUK code can be found on your SIM card pack or by contacting your mobile service provider.
Entering the wrong PUK too many times will permanently block your SIM, so be careful.
Tips for Choosing a Strong PIN
Avoid using easy combinations like 1234 or 0000.
Use a number that is easy for you to remember but hard for others to guess.
Change your PIN regularly for added security.
