Three or more wrong entry of PIN or PUK renders the SIM locked. Now it can only be replaced by the service provider. Of course, on a small payment. So, please call up the help line of your service provider and tell them to give you a new SIM. Incidentally, the number stays the same.

What is the PUK code


its Personal Unlock KEY..........for phone security......actually before PUK u enter sim pin........if wrong pin is entered 5/10 times your sim is locked permanently and sim can only be used after u enter puk code. Please note that pin code is entered by user.....but PUK code is provided by your network service provider company. PUK is generally mentioned on the sim rapper(cover).........in case u have not kept the rapper and u do not know the PUK code and ur phone is asking for it...then please do not try to enter it as too many attempts to enter wrong PUK will lock ur sim for ever and u will have to get a new sim.....so instead of trying a wrong PUK code its better to contact your network service provider (you can call their service number) and he will give u the PUK code for your sim free of cost.
I Hope this clears all your doubts about PUK.

NOKIA RM-579 Model: 2730c-1b, Need to know how to unlock PIN # it is asking for. I got 2 try's left, never have put any PIN # to lock or unlock phone always used 12345 if any thing went wrong did...


Hi, if you enter wrong PIN for three times, you are then given 10 attempts to enter the PUK. (it is printed on the voucher of sim card when you have purchased the sim) Your sim card will be blocked permanently if you still entered incorrect PUK code after the 10th attempt.
And if ever you lost the voucher you have only 2 ways to get rid of the PUK code:
1. Replace the sim card or 2. Call the phone company that released the sim card. They will give you the PUK code once you give them your account details and they have confirmed your identity. Hope this can help you,GoodLuck=)

Hi my sons phone is showing enter PUK code! can you help or do I have to contact his network/supplier? thankyou


PUK code stands for pin unlock code. It comes when you enter wrong code for your pin code three times. It is a security feature of your sim card to avoid unauthorised access.

When you enable pin code on your sim card, your phone automatically asks for pin no. when switched on. If the pin is entered wrongly 3 times. It locks the sim, and asks for PUK code. The PUK code needs to be obtained from your provider. If you enter PUK wrongly 10 times, your sim card will be permanently blocked and you will need to obtain a new sim card. Hence kindly contact your network for the right puk code.
