SIM card question

[android_freak1]

Just a quick question, my SIM card has a PIN protection on it. Does this mean that the SIM card is encrypted?

In any case, I save all my contacts to the phone’s internal storage and that is encrypted by default.

No. To my knowledge there's no way to encrypt a SIM card.

Do I really need to have a PIN to unlock the SIM card even If I do not have anything saved on it?

It's there to prevent people putting your SIM into a phone and using it...

In my opinion it's mostly a legacy feature that's been hanging around since the late 90s/early 2000s. At this stage it's largely useless.

Why is it useless?

Since I don’t store any of my contacts on the SIM card, can I turn the SIM LOCK off?
