Updated August 2022: The PUK code is still the only way to regain access to your SIM card once you're locked out. The PIN Unblocking Key (PUK) is utilized to reset a blocked SIM card. Your carrier will ask you to verify your identity and information before giving you the PUK code, so this information is only good if you're the account holder or have access to the account or SIM card. If you're worried that your SIM card got into the wrong hands and they can use this info to get into the SIM Card, fear not.

If you are ever digging around in your iPhone's settings and manage to accidentally lock yourself out of your own SIM card, then this is how you unlock the SIM card on your iPhone. When you input the correct PUK code, you'll unlock the SIM card on your iPhone, so all voice and data should work once more. The PUK code is typically 8-digits long, so make sure that you type it correctly the first time. You only get 10 attempts to input the PUK Code - don't waste them. If it is not showing up, reboot your phone. If you backed out of this screen, you should be able to access it again by going into Settings and then tapping Cellular, or it may just pop up on its own when you try to access anything involving cellular. Once you obtain the PUK code, input it on the Enter PUK screen.

Make sure you have something like Skype that can make outbound calls, or use someone else's phone. Personally, I called my carrier (T-Mobile) through Skype, because it was the only alternative I had (I only have one phone). You can also try a live chat with customer support via your carrier's website or take it to a carrier store. In this case, you'll want to use another device for calling them. Usually, this can be done by calling 611 from your mobile phone, but you'll be unable to make calls if you are locked out of your SIM card.
