I cannot remember my AT&T LG3 PUK


No one can remember a PUK Code, it can only come from your cellphone carrier as they have blocked it. If you have forgotten the PUK Code they just gave you, then you will need to contact them again.

Tip & 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.

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.

SONY EXPERIA S PUK CODE ?


Your SIM code was locked because you gave it 3 times incorrectly and now phone asks for the PUK code to unlock the SIM.

PUK stands for 'PIN Unlock Key'. It's a unique code that is linked to your specific SIM card and is usually 8 digits long.

The PUK code is unique to your SIM card, so you can only get this from your mobile network. Sometimes they will give you this when you first get the SIM card, but not all networks do this. If you cannot find it, give your mobile network a call or visit their Cutomer's Service and they will be able to give you the PUK code after you have answered some security questions.

NEED PUK UNLOCK CODE


PUK

What is a PUK? PUK stands for Personal Unblocking Key, and it's a code that's associated with a mobile phone SIM card.

Why am I being asked for a PUK? Your mobile phone's SIM Card has a four-digit PIN code enabled by default. If you enter the PIN code incorrectly three times, a lock will be put onto the SIM card, and you need a PUK code to unlock it.

Where do I get a PUK? 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.

If u enter PIN code incorrectly 3 times, PIN will be blocked n phone will ask you for PUK(Personal Unblocking Key). This is a 8 digit code. If u enter Incorrect PUK for 10 times Your SIM will be lock permanently.

Your cell phone service provider can(Call from other no. n ask tell them for puk of ur no.) give you the PUK code aft3r answering simple security question.
Later enter PUK than enter new PIN, confirm new pin. Go to -Setting
-Security
-SIM lock

Disable SIM n Later Phone Lock
PS:(You have to block your PIN to get access to PUK,
Default PIN- 0000, 12345)

Get me a new security code of nokia 7210


The PUK code is not related to the handset. It is associated with your SIM card. When you enable the PIN in your SIM card, every time you switch on your phone, you will be asked for your pin. At given number of tries provided by your mobile operator, that you have provided the wrong PIN (usually operators set it at 3 tries), then you came to the stage called PUK-blocked.

To unlock, you would need the PUK code of the SIM card. The PUK code is usually an 8-digit code. This PUK code should have been provided to you when you purchased your SIM card. Some has the PIN-PUK code printed in the card body of the SIM card, while some attach it as a separate print out. Should your operator failed to provide this PIN-PUK code to you, you would have to get it from your operator. Try calling their customer service. Just like the PIN, the operator as well could say how much tries do you have to successfully unblock the PUK of your SIM .

Hello thanks for using fixya

PUK code is called as PERSONNAL UNBLOCKING KEY. Phone ask for PUK code when you entered the PIN code wrongly several times depending upon the mobile make.The mobile asks for PUK code so that unauthorized persons do not use your mobile for wrong cause.
Very Simple solution is go to your service provider or call them to unlock that code If u have to call rather to go there, Please use some other mobile with same network to call your service provider.The service provider customer care officer will ask for your personal details to check whether the mobile belongs to you only. Tell him the details of your mobile.They will provide you PUK code free.
