PUK codes
The PUK (Personal Unblocking Key) and PUK2 codes are 4- to 8-digit codes
that also usually come from your service provider along with the SIM card.
The PUK code unblocks a blocked PIN code, and the PUK2 code unblocks
a blocked PIN2 code.

requiring the PIN2 code. Contact your service provider for a
