Hello there....well its quite simple...there is nothing wrong with your phone ...its your SIM... if it is asking for a PUK (Personal Unblocking Key) code...call your subscriber and ask them for PUK code,entering this code will reset your sim
if u keep entering wrong your sim will be damaged so call them
If the error message is saying sim damaged call them and ask for a "sim replacement" you will get a new sim while you will retain the same number ,however you will lose the phone numbers and other data stored in sim,this can be free but it depends on the company and how 'customer friendly they are
Hope this helps
Cheers

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 advice 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

Customer's exact description:I work for an Electrical Contractor. Recently we let someone go and the company phone is locked. I need to reset this lock code. The phone is a Kyocera K323P. I need to pass the phone to the next employee, but can't until I get it unlocked. Can you help?

Discussion: Problems of this type can be either Phone 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 all three possibilities.

Unfortunately, I have no idea where you live. Nor do I have the carrier, and the brand of phone. So please forgive the following explanation should it not pertain to you.

There are two cell phone technologies that are used by the majority of the world's mobile phone service providers: Global System for Mobile communication (GSM) and Code Division Multiple Access (CDMA). If you have a CDMA phone, then your phone is not unlockable. End of story. However, if your phone operates on a GSM network, then it might be unlockable.

What's the difference? GSM phones use subscriber identity module (SIM) cards. A SIM card is a small card that's inserted into the phone. It contains all your contacts and settings, and it's linked to your account. You can take the SIM card out, put it into another phone, and if someone calls your number, the new phone will ring. You can also put a different SIM card in your unlocked phone, and your phone will then work with whatever phone number and account is linked to that card. CDMA phones have no SIM cards and must be authenticated by the service provider, which makes unlocking a phone impossible.

If a phone is locked, the service provider has installed some software on the phone that ties the subscriber ID number on the SIM card to the serial number of that particular phone. If the SIM card and phone serial number don't match, the phone simply won't work. The SIM card won't work in other phones, and the phone won't work with other SIM cards.

If you live in North America, you can usually determine whether your phone is GSM or CDMA based on the service provider you use. T-Mobile and AT&T use GSM, while Verizon and Sprint use CDMA. In Europe, almost all phones are GSM.

How can you tell if your phone is already unlocked? In Europe, unlocked phones are more common. In fact, many countries have cell phone portability laws that make it illegal for a company to lock a phone to a specific account (though these laws seem to change frequently). In North America, fewer phones are sold unlocked. If you received a phone for free or at a very low price when you signed a contract for your cell phone service, your phone is almost certainly locked.

There's an easy way to find out for sure: Find a friend whose phone is known to be unlocked. Have your friend place his or her SIM card in your phone, and then call your friend's number. If your phone rings, you know your phone is unlocked. If your phone simply generates an error message, then it's locked.

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 solutions: The process of unlocking a phone is actually quite simple, and doesn't require any technical knowledge. There are three accepted methods for accomplishing the unlocking. For some phones, you just have to enter a numeric code into the phone. For a fee, some service providers will even give you the proper unlock code for your phone. There are also third party companies that provide cell phone unlock codes for a fee that ranges from $5 to about $25, depending on the model of phone you have.

There is a very high probability that your carrier will unlock your phone at one of its retail outlets. However, be forewarned that some service providers will charge you a fee for unlocking your phone.

Secondly, 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, However I've included one formula below.

CNET has several pieces of free software that claim to unlock phones. Click on the following link and perhaps you can find something of interest. Universal Free Unlock Codes Calculator

Lastly, for a fee, there are third party companies that provide cell phone unlock codes at a cost that ranges from $5 to about $25, depending on the model of phone you have. The only company that I recommend is Freedom Unlock and the fee for most popular phones is about Five (5.00) USD. I have no interest in this company and my only contact has been in researching their website.

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:

• 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. 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 forgot my password to my phone and im trying to unlock it how can i fix it without the password


You need to call the phone company that sold you the phone card to unlock the phone.

PUK means "personal unlocking key" .

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

You need to call the phone company that released the SIM card, 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

I need to know the puk code for a samsung r225m


If you have lost your pin then you can enter the pin 3 times, util the PUK lock appears. Then you unlock the PUK calling the phone company that provided the SIM card inside your phone (eg Vodafone, Telecom, Tmobile, Orange, AT&T etc.).

Calling the phone company is the standard procedure to unlock a SIM card, however, if you do not want to call the company you can just replace the SIM card with one compatible with the phone, as PIN and PUK codes are related to SIM, and not to the phone.

NEED RESTRICTION CODE TO ENTER TO MY NOKIA 3595 FORMER AT&T PHONE


  1. Before trying anything else, contact your service provider and askfor an unlock code. Usually, if you've been a customer of theirs forsome time, they will provide you with an unlock code for free. This is,by far, the best way to get your phone unlocked.
  2. Download software to generate the unlocking code. Software isavailable on some websites for free and some pay websites that alsooffer support if things go wrong. See external links below.
  3. Find the Serial number of the cell phone, also known as your IMEI number.This can be done by either removing the back of your cell phone andlooking underneath the battery, or simply by typing in *#06# into yourcell phone. It should be something like: 010082321439976/07951780736
  4. Using the software you have downloaded, enter in your Manufacturer(which is in this case Nokia), and sliding the card out. Put thebattery back in and power the phone on.
  5. You will see a message "Insert SIM Card". Enter all of thecharacters you see in your code, including the # symbols. To get a 'p'press * 3 times, to get a '+' press the * key 2 times, to get a 'w'press the * key 4 times. Disregard any spaces in the code.
  6. In order to unlock your phone you generally need to enter only onecode. Start with the first one. If your phone is not unlocked by typingthe first code (MCC+MNC), use code "7" (Multilock)
  7. Once you have finished entering a code that works you should see amessage that says "SIM is not restricted" or "Restriction off" messagedepending on your model. If not, try entering another code. Message"Cannot undo restrictions" means the phone is "hard-locked" and cannotbe unlocked by code.
i hope this helps

The puk code is a code associated to SIM card , not to the phone.

You have to choices, call the phone company or replace the SIM card inside.

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

You need to call the phone company that released the SIM card, they can retrieve the PUK code from a database for free.

In your case you need to contact your SIM card provider technical support to unlock the SIM.

How to unlock sony ericsson w580i usa mobile to use in india


When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :-
This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone.
They should provide you with instructions on how to enter this code into the phone.
Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.

You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country. This maybe a free service.
The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services. Use Google and search for "Security unlocking code” companies in your area.

My Nokia 6070 says "Restricted" when I insert a SIM card


Have your friend call whatever phone company the cell phone is registered with and ask them for the SIM unlock code. Make sure your friend tells them that he is wanting to unlock the phone so you can use an international SIM card in the phone. Hope this works for you :)

Problem regarding mobile sim card chang


Your phone is asking for a code because it is locked to only work with one phone company. If your new sim is from a different company, you can request the unlock code from your old company, they may or may not give it to you (tmobile usually does, ATT/Cingular usually doesn't). The other option is to use a unlocking service, you can find plenty on ebay. If you didn't change phone companies, your new sim card is most likely bad, have your phone company send you another one.
