PUKs, or personal unblocking keys, are used to unblock a mobile phone
which becomes blocked. Mobile phones may become blocked when a PIN
(personal identification number) is entered incorrectly on three
consecutive occasions. In some instances, the phone may become blocked,
which requires a PUK to unblock it, and in other instances, the SIM
(Subscriber Identity Module) card itself becomes blocked and again will
require a PUK to unblock it.
Mobile phones are also blocked when they are reported stolen and if
there is an outstanding payment on the account.
It is important to differentiate between unblocking phones (using a PUK)
and unlocking mobile phones (using another type of code).
NOTE: It is a criminal offence for anyone to attempt to unblock a mobile
phone, other than the network provider who put the block on the phone.
If your phone has become blocked by mistake, for example you have
entered the PIN incorrectly on three consecutive occasions, then you
need to contact the mobile phone network operator with your details. To
explain a little more, specific to your mobile phone network, You need
to go to your Service providers, web site & navigate your way to the
specific PUK details for your mobile phone network operator. Usually
you have to Register your phone to get a PUK code.
A Pin Unlock Code (PUC) or Pin Unlock Key (PUK) is used in GSM mobile phones and some smartcards to unblock a blocked SIM card. The basic of PUK code is,
SIM cards have their own security
on startup SIM cards ask for PIN code (4 digit)
If user enters it correctly then its accessible
If user enters it incorrectly 3 times (in some 7 times) PIN code is blocked. To stop brute force attempt.
Blocked PIN code is unlocked through PUC (Pin Unlock Code) or alternatively called PUK Pin Unlock Key which is 8 digit.
If PUK is entered correctly user sets new PIN code and SIM is accessible.
If PUK is entered incorrectly 3 times, then SIM is no longer usable or accessible and any data in it is lost.
Sim card security is managed by their providers which are usually network companies like vodafone, 3G, Orange and Virgin or T mobile etc... (Whatever is yours like U-Fone, Warid etc....)
NO ONE else can give PUK code. YOU HAVE TO ASK YOUR SERVICE PROVIDER/NETWORK for PUK.

PUK code in PIN UNLOCKING CODE, which is required when you give PIN number wrongly for 3 times, This code is OPERATOR specific and not phone specific and you have to call you operator and get PUk if PIN is blocked...
if you provide PUK code wrongly for 7 time, you sim may become useless, then you have to buy new SIM
The PUK code is a code associated with the SIM card and not with the phone.
You have only two ways to get rid of the PUK code. Either you replace
the SIM card , or you call phone provider that issued the sim cadr (eg.
At&T, Virgin, Tmobile , Vodafone, Telecom etc.)
PUK means "personal unlocking key" .
The PUK code is asked if you enter a wrong pin 3 times.
You need to call the phone company that released the SIM card, they can retrieve the PUK code from a database for free.
In your case you need to contact your SIM card provider technical support to unlock the SIM.
The PIN and PUK are related to the SIM card, not to the phone.
If you replace the SIM card with a different one, then the phone will not ask for the PUK anymore.
