PIN and PUK

The personal identification number (PIN) protects your UIM card from
unauthorized use. The PIN unblocking key (PUK) can unlock the blocked
PIN. Both PIN and PUK are delivered with the UIM card. For details, contact
your service provider.
If you enter wrong PINs for a specified number of times consecutively, the
phone asks you to enter the PUK.
If you enter wrong PUKs for a specified number of times consecutively, the
UIM card is invalidated permanently. Contact your service provider for a new
one.
