Entering the Puk on iPhone X

The Puk is a number you received along with your SIM card. The abbreviation stands for Personal Unblocking Key. This name comes from the fact that the Puk is the last way to unlock a SIM card or other chip. You don't enter the Puk until you've entered the pin incorrectly three times. Your iPhone X will automatically prompt you to type in the Puk. If you enter the Puk incorrectly, the SIM card will be locked immediately. So be careful not to mistype and double check the number before confirming the entry. You can find the Puk under the pin number in your contract documents. If you have lost the Puk, you must contact your mobile phone provider. You will then usually receive a new SIM card.

This is how you enter the Puk

1. If you have entered the pin incorrectly three times, your cell phone will prompt you to enter the Puk.
2. Type the number and check the individual digits.
3. Confirm the entry.
