Unlock with a PUK Code
The PUK Function window is only available if the SIM card is locked by its PUK (PIN Unblocking Key) lock. Usually this happens
after too many entries of an incorrect PIN code (normally three attempts) and the SIM card becomes locked. At this point it
can only be unlocked using its PUK.
Normally you will be supplied with the PUK code when you purchase the SIM card. If you have misplaced or otherwise
forgotten the PUK code you will need to contact your service provider and request a PUK code for your SIM card.
