Can you give us the proper details of the model of the phone. also tell us the way you got your phone locked.
if it is a lock due to security code then you will need a hard reset. else you will have to contact your service provider.

The only free PIN unlock comes from the carrier who owns that phone that you have found.

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.

How to get a PUK code

The quickest way to get a PUK code is online using My Account. We'll show you this information whenever you need it.

  2. Select Help & Support from the main menu options on your account homepage.
  3. Select Get your PUK code.
  4. Then select Get PUK1 code.
  5. Once you have your PUK code, enter this into your phone to unblock your SIM.
Please enter your PUK code carefully - if you enter the wrong PUK code 10 times, you will permanently block your SIM card and we'll need to send you a new one. alt="en.wikipedia.org">

These directions are for an AT and T phone, but other than that, are the same for any carrier. 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 your phone carrier to unlock your SIM card. You can obtain your phone's PUK code from your carrier in one of these ways: Log in to Your account.online Use a Technical Support Chat Contact your carriers Customer Care Get Your Phone's PUK Code Online Go to the Phone/Device page. 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.

My grandaughter has done something to her phone. it keeps showing puk blocked, how can i unblock it. The phone is a LG u880 model.


Hi,
If anybody tries to enter PIN code wrongly more than 3 times, then the PIN code will get blocked and it will prompt you to enter PUK code. To obtain this PUK code, please call to your mobile network operator customer care. Using this you can unlock your SIM card. If you attemp to enter wrong PUK code more than 10 times, then your SIM card will be blocked and you cannot unlock it anymore. You have to get the duplicate SIM card only.

Please provide your rating to the solution
Thanks

SIM Cards and Unlocking your Phone What is a SIM?

Subscriber Identity Module (SIM): A smart card containing the telephone number of the customer, encoded network identification details such as: Call Forwarding, Caller ID, etc., the PIN, and other user data such as the phone book. T-Mobile customers can move their SIM card from any T-Mobile branded phone to any other T-Mobile branded phone without the need to contact Customer Service to activate the new phone. Your rate plan and phone number will follow your SIM to the new phone.

SIM Error Messages:

  • Invalid SIM: This error means that the SIM you have inserted into your phone is either inactive or is not compatible with our service. You may purchase a new SIM card from a T-Mobile retail location. Locate a T-Mobile retail store near you.
  • Insert SIM: Your SIM is either not inserted in your phone or is inserted improperly. Please remove and re-insert your SIM card. If you continue to receive this error message, your SIM card or phone may be defective. You may take your phone and SIM to a T-Mobile retail store for further assistance and a free SIM card replacement if necessary. Locate a T-Mobile retail store near you.
  • Unregistered SIM: This error may occur if your SIM card is not fully activated or if the SIM card registered to your account is different than the SIM you have in your phone. For assistance with this issue, please contact Customer Service.
  • SIM Not Ready: This error occurs when you have just powered your phone and is due to the phone not being fully initialized. Please wait a few moments before accessing your phonebook or placing a call.
  • OTA OK: This message is displayed when your phone receives a network update, phonebook download, or an Over-The-Air t-zones or Picture Messaging configuration. NOTE: These messages are free of charge and will not be billed to your account or pulled from any text message bucket.
  • Enter PUK: These errors can occur if you have entered your SIM PIN three times incorrectly. If you receive this error message, please contact Customer Service for a PIN Unblocking Key (PUK) to restore access to your phone.
  • Check card, Card Blocked See Supplier, Blocked, SIM Blocked, or Contact Card/Service Provider: These errors may occur if you have entered your PUK ten times incorrectly. If these errors display your SIM is unusable and you will need to purchase a new SIM card. You may purchase a new SIM card from a T-Mobile retail location. Locate a T-Mobile retail store near you.
SIM PIN:

A SIM PIN can be used to prevent access to your phone. When enabled, your phone will prompt you for the SIM PIN when the phone is powered on. Entering the wrong PIN will prevent you from making or receiving calls. SIM PINs are different from a Security Code that your phone may use to secure other phone functions. Please check your phone’s manual for further security details.

T-Mobile SIM PIN numbers are set to default values before purchase. If you change your SIM PIN, it is recommended that you keep record of the new PIN in a safe location. T-Mobile cannot retrieve a lost or forgotten SIM PINs.
  • SIM PIN1: 1234
  • SIM PIN2: 5678 (Only available on select phones)
SIM Unlock:

T-Mobile branded phones operating on the T-Mobile network may only use T-Mobile SIM cards. To use a T-Mobile branded phone on another wireless carrier's network with a non-T-Mobile SIM card, you must first request a "SIM Unlock" code from T-Mobile. Conversely, if you have a phone from another North American wireless carrier, you may need to request a "SIM Unlock" code from that carrier before being able to use a T-Mobile SIM card on the T-Mobile network.

SIM Unlock Requests:

T-Mobile customers must meet the following eligibility requirements before contacting Customer Service to request your SIM Unlock code.

The following restrictions apply to all account types:
  • T-Mobile can provide SIM Unlock Codes only for handsets sold by T-Mobile USA, with the exception of Danger Sidekick devices. T-Mobile can obtain SIM Unlock Codes for companies acquired by t-Mobile USA (VoiceStream, Aerial, Omnipoint, SOL, Digiph, PCS One, and Powertel).
  • SIM Unlock Codes will only be provided after your account has been active for 90 days. Only one unlock code may be provided per customer every 90 days.
  • No SIM Unlock Codes will be provided within the 14-Day Buyer's Remorse period. Customers who purchase phones in CA California or via Amazon.com are granted a 30-Day Buyer's Remorse Period.
  • SIM Unlock Codes are not always available from the Manufacturer. However, T-Mobile will make a dedicated effort to obtain the SIM Unlock code. Note: Other restrictions may apply depending on account type.
Goodluck
