What is PUK code. How to get this?

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.

ip & How-To about Cell Phones Your phone is asking for a PUK code?
Is your phone asking for a PUK code. PUK = Personal Unlocking Key. Personal Unblocking Key, or PIN Unblocking Key.

This can only come from your cellphone carrier and usually the company that still owns the phone under the agreement. Sometimes it is because you have put another SIM card in it, and they own the phone and need you to use them as carrier to get the price of the phone back, or you are in default of payment, or on a Pay as You Go plan, it is over expired. I can also happen if you have entered the unlock code wrongly three times. This often happens when a phone is stolen or lost and has been found by or sold to someone else who then try and use the phone.
Wikipedia
A personal unblocking code (PUC), also known as a PIN unlock key (PUK), is used in 3GPP mobile phones to reset a personal identification number (PIN) that has been lost or forgotten.
Most mobile telephones offer the feature of PIN protection. After switching on the phone, if the PIN security function is active, the user is requested to enter a 4-8 digit PIN enabling the phone's non-emergency calling functions. If the wrong PIN is typed in more than three times, either the SIM card, the device, or both become locked. They can be returned to their original unlocked state by entering a PUC, provided by the service operator after verification. If the wrong PUC is entered ten times in a row, the device will become permanently blocked and unrecoverable, requiring a new SIM card. Cellular phone users are therefore advised by most providers to keep their PUC written down in a safe place separate from the device.
The PUC (PUK) is a SIM-specific code assigned and provided by the service provider.
Once you enter the PUK code, you must set a PIN. The PUK and PUK2 are used to unlock the PIN and PIN2 codes respectively if your SIM card is blocked
From Bell
The PIN unblocking key (PUK; sometimes called personal unlocking key) is a master security code for unblocking and resetting the personal identification number (PIN) for your SIM card. For added security, the PUK is unique to your SIM card.
If your PIN code is active and you enter it incorrectly three times, your SIM card will be blocked. You won't be able to use your phone, except for emergency calls. You must enter your PUK into your phone to unblock the SIM card.
If your SIM card becomes blocked, Contact us to get your PUK. You may be able to do it from the website or your cellular provider. This is from Orange - T-Mobile in the UK.

Your phone can become blocked in a number of ways - one of them is if you enter your SIM card PIN number incorrectly three times in a row.
To unblock your SIM card, you will need to use something called a PUK (Personal Unblocking Key).
Remember that unblocking is different to unlocking. Read more information on unlocking your device.

my phone asked for a puk code i kept on guessing and eventually it said sim blocked and i cant do anything why?


A PIN Unlock Code (PUC) or PIN Unlock Key (PUK) is used in GSM mobile phones and some smartcards to unblock a blocked card.
Because you tried too many times without a correct code, your SIM card is blocked and needs to be replaced. I would go to your Cell provider's store and purchase/replace yours. :)

what is 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 card.
A PUK code is required if a GSM SIM card was locked after entering the wrong PIN code three times in a row. Entering a wrong PUK code ten times in a row disables the SIM card permanently. Both the PIN and the PUK codes are supplied by the operator, but only the PIN code can be changed by the user.

Whats the PUK Code?


Hi, a PIN Unlock Code (PUC) or PIN Unlock Key (PUK) is used in GSM mobile phones and some smartcards to unblock a blocked card.
PUK code is the Pin Unlock Key code.
when you get your SIM card, along with the original PIN, the PUK code is also written just underneath it, so if you have that original card from where you got your SIM card, then it will be there.
