How to change or remove the SIM PIN on your iPhone or iPad

SIM cards usually require a PIN (Personal Identification Number) to unlock and connect to the mobile carriers, so that you can make phone calls and use the internet. SIM PINs are a security feature that protects unauthorized people from using your SIM card in situations such as when your phone is stolen or lost. However, some people do not want this feature on, while others want to change the default PIN assigned by their mobile carrier and set their own. If you own an iPhone or an iPad and you want to change or remove the SIM PIN for it, read this tutorial, and find out how:

Do you use a SIM PIN on your iPhone or iPad?

SIM PIN can be a good security measure if you want to protect your SIM from unauthorized access. However, that is true only if you set a custom PIN that is different from the default one set by your mobile carrier. Also, although it is not recommended, some people prefer not to have it enabled at all. Do you use a custom SIM PIN on your iPhone/iPad?
