The phone doesn't have a puk code, every simcard has its own puk code.

if you have entered the puk code wrong too many times, you can't enter it anymore, time to call your service provider for instructions or possibly replacement sim card. I've explained more on this page http://www.bukisa.com/articles/19406_puk-code

if you insert a new sim card to the phone it wont ask for puk code, as its only the simcard that gets locked after 3 wrong pin codes.
Thanks,
Ekse

Hi,

My name is Ben and I'm your guru, i.e., mentor, an influential teacher or popular expert: a management guru. - origin from Sanskrit, 'weighty, grave', for today.

Problem areas: The question most honest people ask me is, "Is it legal to unlock a cell phone?" In Europe, the answer is generally yes. Though laws differ from country to country, they tend to favor consumers over companies. In the United States, the answer is also yes. The U.S. Copyright Office issues rulings every three years, and in 2006, they declared that unlocking a cell phone does not infringe on the copyright of the phone manufacturer or service provider, and therefore isn't prohibited.

In order to provide the customer with precise information, one must have the following information.

• Phone description including the make and model.
• The name of the subscriber's carrier (a.k.a. service provider).
• Information as to whether it is the phone or the SIM that is locked.

Possible solution: You can unlock your phone on your own. For some phones, you just have to enter a numeric code into the phone. I don't hand out these numbers because they vary from company-to-company and usually don't work, But if you have the patience, there are several instructional videos on www.youtube.com that provide some useful data. However, I don't recommend them because most of these videos are only free to look at. Yes they are trying to sell you something, like their service.

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. (This is the easiest solution)

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

• 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."

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 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 #

Display Handset IMEI
*# 06 #

This was wordy but hopefully it helped you.

I mistakenly entered the wrong Lock code, now the phone is asking me to enter the PUK code which I don't know what is it? please help me ,,


You should call your operator and ask for the PUK, there is no other way. PUK is SIM related, so they will know your PUK code. Don't trying guessing it, you will have to take it to service if you type in a wrong PUK!

Hi,

My name is Ben and I'm your guru, i.e., mentor, an influential teacher or popular expert: a management guru. - origin from Sanskrit, 'weighty, grave'.for today.

As you evaluate my advise 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.
• 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.

Subject: How to unlock a cell phone and/or SIM card

Customer's exact description: I forgot my password to my samsung intercept and now all I want to do is reset the phone, but I don't know how

Discussion: Problems of this type can be either Locked SIM card Locked, or Lost Password. Customer did not provide sufficient detail to narrow the problem.

Solution: Provide instructions on how to deal with the two possibilities.

Phone has come up with PUK Lock on it. It needs a PUK code but to my knowledge it has never had one of these before. Turning the phone off & then on again doesn't do anything.


Its not the phone, but the sim that requires a PUK code. If you check your original sim starter pack, you would see your PUK code printed on it. I want you to know that its quite different fron the four digit pin code. Enter this puk code to unlock your sim. But if you cant find your starter pack, then I want to believe you know the number of you customer care, you could ask one or two people if you dont. Then, when you know the number, use some one else's line, but of your same network, perhaps a friend's, and call the customer care agents. Tell them your sim is requesting a PUK code which you dont have access to. Give them your phone number, and they should sort out the rest for you.
I hope this helps you.
Have a nice day.

You have entered the wrong SIM password so it is locked. You can unlock it easily. You have to call your network service provider and ask for PUK code. They can ask you SIM no. which is printed at the back of SIM card.
Then you can enter the PUK code and use the phone again.

PUK stands for Personal Unblocking Key. This is a uniqueeight-digit code specific to your SIM card. This is required when the PIN numberto unlock your mobile phone is entered incorrectly 3 times. You are then given10 attempts to enter your PUK code. If an incorrect PUK code is entered afterthe 10th attempt, you will block your SIM card permanently and will require anew SIM card from your mobile phone provider.
PUK codes can be obtained through the following ways - The PUK code is in your SIM card documentation Starter Pack.If you do not have this then -Please contact your phone service provider.
Your cell phone service provider can give you the PUK code once you give themyour account details and they have confirmed your identity.

My phone is locked i don,t know the pin sonnyericson w705


Hi,

PIN CODE is SIM dependenet and not phone dependent

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

NOTE: You should ask your service provider,get the PUK, give the PIN 3 times wrongly and it asks for PUk,provide the PUK and set the new PIN..
