Yes, It's only your network operator who can unlock PUK on your request. There is no another way to unlock PUK. Just call him on their customer support centre.

I need a puk code for a samsung sgh-g600


the pin unlock key, is when you have entered a wrong pin for more than what is allowable by the phone/network.
you can get your PUK code from your service provider or if you are using a prepaid simcard, at the back of the card (where you take out the sim) there is a portion that you can scratch off, that is your PUK code or when you buy your sim card there is a piece of paper inserted on the pack tat contains your PUK code (PUK 1 and PUK 2)

Tip

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.

Puk code is being asked for


Hello, If you're being asked to enter a PUK, you will need to contact your network operator to get your sim card unlocked. This is for security reasons. Note that only your mobile phone network operator can legally provide you with a PUK code to unlock your SIM card. Thank you for using Fixya

Trying to unlock orange phone need a puk


A request for a PUK code ("Personal Unlocking Key") will appear on your phone if your SIM card PIN code is entered 3 consecutive times incorrectly.

Your SIM card will then become "PUKed" or Blocked. This is a security measure to protect your service.

You need to call the Customer Service department of your cell phone provider and they will give you the PUK code which will unblock your SIM card.

My pin has been blocked, I need the PUK code


The PUK is a unique number that is assigned to your SIM card. Your SIM is blocked not the phone. If you try another SIM in the phone it should work just fine. In order for you to unlock your SIM, you need to check the papers that you got with your SIM card, the PUK1 and PUK2 should be on that paper. When your phone is security code lock usually you need the PUK2 to unlock it but some phones use the PUK1 to unlock it, you'll need to get this information from your service provider. If you don't have the papers for the SIM you'll need to contact your service provider for the PUK, some companies may require you to verify that you are the owner before they provide it to you.

Puk blocked


Hi and welcome to FixYa,

A PUK (Personal Unblocking Key) is the code required for enabling/unlocking a sim card. This disabling/lock is a result of erroneously entering the PIN (Personal Identification Number) multiple times. Depending on the SIM card issuer, erroneously entering the PUK code multiple times would result to a permanently blocked/disabled SIM card. The PUK code is an OTW (one time write) only and therefore the only way to open the card is with the PUK code.

In all instances, it has nothing to do with the phone itself but with the SIM card, hence, the LG Vu CU920 would still work with another SIM card.

Hope that this be of initial help/idea. Good luck and thank you for using FixYa.

I Need puk code for my sony ericsson k220i model


PUK means "personal unlocking key" .

The PUK code is asked if you enter a wrong pin 3 times.

You need to call your phone service company, they can retrieve the puk code from a database for free.

In your case you need to contact your SIM card phone 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.
