WARNING - You get three attempts at entering the correct SIM PIN before the SIM is blocked. A *PUK code is required to unblock a blocked SIM.
*The PUK (Personal Unblocking Key) code is a code consisting of 8 digits. It is used to unblock your SIM card when you entered 3 times a wrong PIN code. A card blocked by the PUK code cannot be unblocked; it cannot be used any further and you have to replace it.
