You should contact your operator, the PUK code doesn`t have any relation to security code... please note that the PUK code only have 10 chances wrong input, after that your SIM card can`t be used again

About PUK code

A PUK code (Pin Unlock Key) is required when you enter an incorrect PIN (Personal Identification Number) 3 times. After entering the wrong PIN 3 times, the card will be locked and you will need to get a PUK code from your service provider to unlock it.

Once your PUK has been send to you, you should enter it into your phone to set a new PIN code, that will be four zeros "0000"

Note: If the wrong PUK code is entered ten times, the SIM card becomes invalid and you will need to get a new SIM Card. The phone will display "PUK blocked call operator". that will cost you money.

So please be carefull before entering PIN and check twice.

Best regards

I tried making a pin code for my lg GU29of model and it asked me what the default one is i typed what it said and it kept saying invalid pin after saying invalid a few times it switched me to puk code and...

Your PUK is listed on your account. You can call your customer service and they should be glad to provide that for you.

AT&T allows you to check that yourself if you log into your account online.

It's a rather long number so make sure you can see it clearly, or write it down before you sit down to type it in. NOTE: You only have 10 attempts to enter the PUK before it will lock your SIM permanently and you'll need to purchase another SIM to replace it.

Before trying the PUK (which is a PIN Unblocking Key), power your phone off and then back on. Then enter the PUK. Once you enter the correct code it'll ask you to enter a NEW PIN. Remember that one as that will be your new PIN.

If you get it wrong enough times it'll go to the PUK again.

Hello i have china phone i9++i model in security set up sim2 it was asking puk2 pl send the puk2


The easiest way to get the PUK code is to call your service provider, such as T-Mobile or Verizon. They need to verify your cell phone number and your IMEI number and they will provide you with the PUK code.

Hope this helps,

Security access code problem

Security access code is different from PIN code. If you phone is asking you for a PUK code that means you have entered wrong PIN more than 3 times. Please do not try to guess the PUK code, because if you Enter a wrong PUK for a particular number of time (mainly more than 10 times) your sim card will be damaged and un-usable. There is no way to make it work. You will have to replace the SIM.

To get a PUK code you will have to call the Customer Care of your service provider and they will give you a PUK code agains your number, which will help you to generate a new PIN.

PS: There is no other way or software to get a PUK code. Hence do not try to guess it

I locked the 'PUK' code on my phone and it wont unlock.

You need to call your customer service center. The PUK code is a SIM password and activates if you attempt to input in incorrect security code too many times...I think 3 is the limit. Once you call them they should be able to give you that code and PIN.

Puk code

PUK code is asked when you have entered your security code more than thrice. To reinstate your mobile you have to contact your sim service provider.
Just call the customer care from any other mobile & you'll get your PUK code. Some operators ask for few personal details. After getting the PUK code, enter it in your mobile & it will ask for new security code of your choice. Enter it twice & your mobile is ready.
