Please i lost my sim puk and i can't make use of my sim

Your iPad 2 must have 3G, with a sim card. For the sim you need the pin and after 3 misses you need the puk. The puk is on the letter or card that came with the original sim card. On that letter is the pin and puk. sometimes you have to scratch away the metal layer.

If you want to unlock an iPad, with the lock code on, and forgot your pass code you have to enter the correct password that belongs to your Apple ID. It will be partially on the screen. If you really messed up, setting up security, and lost unlock code and your Apple ID password. Only Apple can help. For that you have to take iPad, invoice, Prove of your identity (Passport) to the Apple store and hope they will unlock your iPad. With iOS7 Apple mede a very good security system. And while setting up the iPad and the security, you are warned several times what to do t make sure you and only you could enter the system.
Be aware if Apple does reset your iPad, all data now on the iPad will be lost.

Please call the Customer Care of your Network Operator (sim card provider), they will tell your the code. There's no other way or no means to get the code except from the Service Operator. They might ask your few questions related to the Sim Card, like your name or your address, tell them promptly and they will give you the puk code for your sim card. It's also important to note down the Sim Card Number (number written on the sim card) if in case they ask you the sim number. You will also be assisted on how to disable the security settings.

Note: if you keep entering random/unknown numbers/codes, the sim card will be locked and will be rejected. It'll not be usable anymore. Good luck.

Hi there, i suggest you please contact your service provider for the PUK CODE. PUK code is protect your sim card. For more details please read the below topic. Its much clear to you.
1. My phone is requesting a PIN/PIN2/PUK/PUK2 code.
Your phone is equipped with one or more codes to protect it against unauthorised use. The PIN and PUK codes actually protect the SIM card, a small card inside your phone that establishes the network connection.
In most cases, your operator or service provider is the best source of assistance with PIN and PUK codes.

• The most common code is the PIN (Personal Identification Number) code, which you set yourself and can activate and inactivate by following the instructions in your user guide.
• The PIN2 code is a PIN code which acts as a second layer of protection for certain features of your phone. It functions in the same way as the PIN code, and more information is available in your user guide.
• If the PIN code is entered incorrectly multiple times, your phone may request a PUK (Personal Unblocking Key) code. The PUK code is an 8-digit code provided by your operator or service provider.
• If the PIN2 code is entered incorrectly multiple times, your phone may request a PUK2 code.

Please contact your operator or service provider for assistance with your PIN and/or PUK codes. If you have already contacted your service provider and the code provided did not work, you will have to obtain a new SIM card from your operator or service provider.

2. My phone is requesting a security code.
Your phone is equipped with one or more codes to protect it against unauthorised use. Please note that the security code, which protects the phone itself, differs from the PIN code, which protects the SIM card.
If your phone is prompting you for a security code and you have not activated one, please try the following:

• Enter the default security code: 12345. Only try this once.

If your phone still requests a security code, please bring it to the nearest Nokia care point for inspection. You can find care point addresses from the drop-down menu at the bottom of Repair.
Please note:

• Some operators configure phones so that they only work with their brands' SIM cards. In this case, if you enter the wrong code three or more consecutive times, the phone may lock permanently. If this happens, contact your operator or service provider for assistance.
• In other cases when you enter the wrong code three or more consecutive times, the phone switches to a "sleep mode" and does not accept any entries for the next 15 minutes. In this case, power the phone off, then back on, let it sit idle or untouched for 15 minutes, then try again or bring it to a Nokia Care point.

3. My phone displays "SIM card rejected" or "SIM card unaccepted".
The SIM (subscriber identity module) card is a small card inside your phone that establishes a network connection. The SIM card is provided by your operator or service provider. In most cases, they are the best source of assistance with SIM card problems. Your phone may display a SIM card error message if:

• The SIM card is out of alignment. If the phone has recently been dropped, bumped, or opened, the SIM card may need adjusting. Follow the SIM card installation instructions in your user guide.
• The PUK (Personal Unblocking Key) code is entered incorrectly multiple times. This can inactivate the SIM card. If inactivation appears to be permanent, contact your operator or service provider for a new SIM card.
• You have recently changed service providers. In this case, either your SIM card or your phone may be configured for your previous operator and may require reconfiguring. It may also be that your phone is configured so that it cannot be used with a SIM card from a different operator or service provider. Please contact your current operator or service provider for assistance.

If none of the situations above apply and you continue to receive this error message, your SIM card may be damaged. Please contact your operator or service provider to have the SIM card tested and/or replaced. Or alternately, bring your phone to the nearest Nokia care point for inspection. You can find Care point addresses from the drop-down menu at the bottom of Repair.
Thanks & hope its helpful for you.

You enter the PUK code, when the SIM has been locked by too many attempts at entering the PIN code for the SIM.

When the PUK code is needed, the phone will specifically ask you to enter it. If you want to trigger the PUK code request, enter the PIN code for the SIM card incorrectly a few times. There is no key press codes to trigger the PUK code prompt.

Each PUK code is specific to each SIM card, and has nothing to do with the phone itself.

And the PUK code is also not related to the phone security/lock code (the default for the security/lock code on the phone is 12345 on Nokia phones).

SIM pin code:
This is a pin code that locks the sim card until you enter the correct code. This protects your account, even
if your sim is put into another handset. To reset it, you need the PUK code:
Pin Unlock Code (PUK)
If you miss key (or forget) your SIM pin code, and enter the wrong one 3-5 times in a row, the SIM will lock up, and you’ll need to enter the PUK unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don’t try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled.
Phone Security Code:
This locks the handset, as opposed to the sim card. You can also set some handsets to only accept a “new” sim if the phone security code is entered. To reset it, you need the Master code code:
Master Reset Code
Sometimes known as the Master Code, this allows you to unlock a handset if you have entered the Security Code wrongly too many times.

The default security code for Nokia is 12345
I need the IMEI (International Mobile Equipment Identity) number. Type this code in your phone to get it: *#06# you can also find it beneath the battery.
Then I’ll give you the Master code to reset your Security code.

Which is the one that you want?
The default security code for Nokia is 12345
