PUK Codes

A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from AT&T to unlock your SIM card.

Since I don't know the name of you carrier, I'm using AT&T as an example. Most carriers use the same methodology though the wording may be different.

You can obtain your phone's PUK code from AT&T in one of these ways:

Take the phone into your carrier's retail outlet.

OR

• Log in to myAT&T online
• Use our Technical Support Chat.
• Contact Customer Care


To get your phone's PUK code online:

? Log in to myAT&T.
? From the myAT&T tab at the top of the page, hover over the Wireless link and select Phone/Device under the My Wireless Service heading.
? From the My Phone/Device screen, select the Unblock SIM Card link under the My Make & Model heading.
? The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card.

Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code.

Note: If you enter the wrong PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator."

Second Solution:
You can also do it without any assistance from anyone. However, be sure to read the following carefully because there are pitfalls. If you want to try to do it yourself, just click on the following link: Universal Software Solution for Unlocking a SIM Card

Although most people remember their primary SIM PIN code, those other codes - used for various verification purposes - are never to be found when needed. Below I've included a set of short codes which, when entered on a handset's standby screen, will let you easily change PIN and PUK (short for Pin Unlock Code) codes - but keep in mind, they may not work with all handsets and mobile operators.

More importantly, when changing one's PUK codes there'll be no help to get from the mobile operator if the new codes are forgotten, so make sure to write any changes down alongside the old PUK codes.

The Final Solution:
The following methodology does not work for every phone. Perhaps you'll be lucky. Also, please note that the codes should be entered without the spaces shown below.

Change SIM Card PIN
** 04 * old PIN * new PIN * new PIN #

Change SIM Card PIN 2 (Write down the new code)
** 042 * old PIN * new PIN * new PIN #

Change SIM Card PUK (Write down the new code)
** 05 * old PUK * new PUK * new PUK #

Change SIM Card PUK 2 (Write down the new code)
** 052 * old PUK * new PUK * new PUK #

As you evaluate my advise.solutions and suggestions, there are a few things you must keep in mind:

• I did not diagnose your problem and am therefore only able to evaluate what you tell me. For example, if you ask me a fuse location, that doesn't mean that I can tell you the reason why the fuse blew. Keep in mind that I'm limited in my analysis to what you tell me.
• A thorough diagnostic approach involves the use of technical equipment, such as voltage meters. scanning equipment and other sophisticated devices.
• Lastly, fixing one problem can very easily reveal a problem with something that you might consider unrelated. If that happens, you might want to view me as being incompetent.

Discussion: Problems of this type can be easily solved and the short answer is YES. However, since I don't know the name of your carrier, I'll give you the various solutions including contacting customer service.

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.

I don't quite understand when you said "I've lost my sim card, how to get my PUK Code?", PUK code is specific for every sim cards, so if you have lost that sim card which was blocked, I don't think you will ever need the PUK code for that sim card. But if you mean that your sim card is blocked and you are being asked for PUK Code, please follow the instructions given HERE. This is one of my "how to's" about PUK Code issue.

Let me know if ou need further help.

Good Luck.

Thanks for using FixYa.

The PUK or 'Provider UnlocK code' is required when you enter the wrong phone unlock code a few times (normally 3 times): this PUK code normally comes with your SIM card documentationbut can be obtained from your cellular service provider help desk.
Do not attempt to enter the wrong PUK code more than a couple time as after a certain number of attempts (5 to 10 times), the SIM card will be permanently disabled and you will need to get a replacement SIM card.

Hope it helps.
