Setting the PIN of your SIM card
A personal identification number (PIN) is delivered with your SIM card to

enter the PIN each time you turn your phone on.
Before you perform the following operations, make sure you have obtained
your SIM card's PIN from your service provider.

The SIM card allows only a limited number of consecutive retries if an
incorrect PIN is entered. If this limit is exceeded, you must enter a PIN
unblocking key (PUK), which you can obtain from your service provider.
The number of consecutive attempts to enter the PUK incorrectly is also
limited. If this limit is exceeded, your SIM card will be permanently
disabled. For details about these limits, contact your service provider.
