PIN and PUK
The personal identification number (PIN) protects your USIM/SIM
card from unauthorized use. The PIN unblocking key (PUK) can
unlock the blocked PIN. Both PIN and PUK are delivered with the
USIM/SIM card. For details, contact your service provider.
If you enter wrong PINs for three times consecutively, the phone
asks you to enter the PUK.
