I mistakenly entered the wrong Lock code, now the phone is asking me to enter the PUK code which I don't know what is it? please help me ,,


You should call your operator and ask for the PUK, there is no other way. PUK is SIM related, so they will know your PUK code. Don't trying guessing it, you will have to take it to service if you type in a wrong PUK!

PUK stands for Personal Unblocking Key. This is a uniqueeight-digit code specific to your SIM card. This is required when the PINnumber to unlock your mobile phone is entered incorrectly 3 times. You are thengiven 10 attempts to enter your PUK code. If an incorrect PUK code is enteredafter the 10th attempt, you will block your SIM card permanently and willrequire a new SIM card from your mobile phone provider.
PUK codes can be obtained through the following ways - The PUK code is in your SIM card documentation Starter Pack.If you do not have this then -Please contact your phone service provider.
Your cell phone service provider can give you the PUK code once you give themyour account details and they have confirmed your identity.

I bought one SAMSUNg SGH-J700i. When I am trying to poweron the phone it asks for Phone lock password which is 1234 and opened but immediatly it asks for SIM loack password. But I am not awrae of any SIM...


If u enter PIN code incorrectly 3 times, PIN will be blocked n phone will ask you for PUK(Personal Unblocking Key). This is a 8 digit code. If u enter Incorrect PUK for 10 times Your SIM will be lock permanently.

Your cell phone service provider can(Call from other no. n ask tell them for puk of ur no.) give you the PUK code aft3r answering simple security question.
Later enter PUK than enter new PIN, confirm new pin. Go to -Setting
-Security
-SIM lock
-off
Disable SIM n Later Phone Lock
PS:(You have to block your PIN to get access to PUK,
Default PIN- 0000, 12345)

I tried to apply a pin lock to my LG GD510 and it asked for my PUK code so i kept trying to enter the correct one and it didn't work. when i next turned my phone on it came up with "PUK blocked"...


After entering the wrong PUK code 10 times in a row, the SIM card becomes permanently invalid or locked. The only solution is to purchase a new SIM card.

Pls, my phone is asking me to enter PUK2 code, though i entered the normal PUK code but it kept repeating "ENTER PUK 2 CODE" , help me pleasssssssse


Hi,

PUK code and PIN Code:

Please dont try more than 3 times.If you try more than 3 times the Sim will get locked.And it will ask for PIN code.Both these PUK and PIN code can be given only by the network service provider. Please call the network service provider of your mobile.And ask him to provide the PUK code or PIN code.He will ask you some basic details like name,date of birth for his verification.And he will provide you the PUK and PIN code.This is done for free of cost.

Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thank you for using fixya have a nice day:-)

My phone is asking for a puk...then it asks me to set up a new pin.....i have no idea what a puk is and I have never set up a pin....help


  • if its the PUK code you need contact your customer service...they are the only ones that have it. as far a setting up a pin you shouldnt have to but if its asking for one most all phones default phone lock code is 1111 but the phones sercurity default lock code is 0000 once you have the PUK code and have entered it....try the 1111 first then it will have you enter it again if that dont work try the 0000 If the incorrect lock code is entered more than 3 times the phone will display "ENTER PUK". just enter the PUK code again
