A PIN Unlock Key or Personal Unblocking Key
(PUK code) is a unique number that’s used to
unlock the Subscriber Identity Module (SIM)
card for your phone. The SIM card contains
all the account details your phone needs to
make and receive calls—including generated
passwords, or PIN codes. If you forget or lose
the PIN code, you can use the PUK code to
unlock the SIM card. You will be prompted for
the PUK code if you enter the PIN code
incorrectly three times on your phone. You can
get your PUK code from your carrier.
Step 1
Browse to your carrier’s website and enter
your account login, or follow the prompts to
register. This will include entering details such
as your telephone number, name and a
password. The password on the website
account is unrelated to the SIM card
password.
Step 2
Select “My Phone” or “About Phone” or
something similar and look for a settings
summary.
Step 3
Enter the PUK code from the website on the
phone when prompted to do so. The phone
will prompt you after three incorrect PIN
number attempts. You will have 10 attempts
to enter the correct PUK code before your SIM
card locks up and becomes unusable.
Step 4
Enter a new four- to eight-digit PIN code when
prompted to do so. The phone will prompt
you after you have successfully entered the
PUK code.
Re-enter the desired PIN code to confirm.
Tip
The default PIN code is often 0000 or the last
four digits of your cell phone number.
Warning
If you fail to enter the PUK code correctly on
the 11th attempt, the SIM card will stop
working and you will have to get a new one
