Entering Your PIN Code

The SIM card is protected by a PIN (Personal Identification Number) that you must enter the first time you use your phone or each time it is switched on, if this option is set (see page 50).

• For more details about the PIN and PUK codes, refer to the glossary on page 77.

If you wish to change your PIN, see page 51.

If you enter the wrong PIN three times in a row, the card is blocked. To unblock your phone, you must enter the eight-digit PUK (PIN Unblocking Key) that comes with your SIM card.

If you enter the wrong PUK ten times in a row, your SIM card will be permanently blocked. You must then contact your network operator.
