SIM card lock The SIM card lock protects your subscription, but not your phone itself, from unauthorized use. If you change SIM cards, the phone still works with the new SIM card. Most SIM cards are locked at the time of purchase. If the SIM card lock is on, you have to enter a PIN (Personal Identity Number) every time you turn on your phone. If you enter your PIN incorrectly three times in a row, the SIM card is blocked. This is indicated by the message PIN blocked. To unblock it you need to enter your PUK (Personal Unblocking Key). Your PIN and PUK are supplied by your network operator.

If the message “Codes do not match” appears, you entered the new PIN incorrectly. If the message “Wrong PIN” appears, followed by “Old PIN:”, you entered your old PIN incorrectly.
