I don't know password How will open the lock

Hello and Welcome to FixYa!
SIM Lock codes are all service provider (Your SIM / Your Connection) dependent, you can never get it from anywhere else, never get fooled and pay for it to anyone.
All you have to do is to call your service providers via some other phone or landline and talk to a CSR, ask him for the code. He will first authenticate your ownership and will give you your code in ruturn, for free, Its your right to know your PIN/PUK and all other SIM codes.
I hope you have a clear picture now.

PUK stands for Personal Unblocking Key. This is a uniqueeight-digit code specific to your SIM card. This is required when the PIN numberto unlock your mobile phone is entered incorrectly 3 times. You are then given10 attempts to enter your PUK code. If an incorrect PUK code is entered afterthe 10th attempt, you will block your SIM card permanently and will require anew 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.
