WHAT IS A PUK CODE_Why Phones Prompt for a PUK code.
The PUK code is unique to your SIM card, so you
can only get this from your mobile network. Sometimes
they will give you this when you first get the SIM card, but not all networks
do this. If you cannot find it, give your mobile network a call and they will
be able to give you the PUK code after you have answered some security
questions."
Why
Phones Prompt for a PUK Code
On
a GSM handset, the network information is stored in the SIM card instead of in
the handset. This makes it easy to transfer the number from one phone to
another, but it's also a security risk. A lock code on the handset doesn't
prevent someone from taking the SIM card out and putting it in a different
phone. If you lose your phone, someone could make unauthorized calls on your
account on another handset. The SIM PIN is a lock on the SIM card itself. If
you input the SIM PIN wrong three times, the carrier's network locks the SIM
and the phone displays an "Enter PUK Code" message. "
Why
Some Tracfones Don't Require PUK Codes
Unlike
most cellular carriers, TracFone does not own their network hardware. They are
a cellular reseller that lease space on other carriers' networks. In areas
where its leasing partner is T-Mobile or AT&T, Tracfone sells GSM handsets.
In other areas, it sells CDMA handsets. CDMA phones do not use PUK codes
because they do not have SIM cards. The network information is stored in the
handset's memory, and the phone's serial number is connected to the account on
the carrier's network.
Getting
the Correct Code
When
your LG TracFone prompts you for the PUK code, do not enter any more codes.
Even if you enter the correct SIM PIN, the phone will not accept it. You also
cannot use an old PUK code to unlock the SIM. The PUK code is randomly
generated by the carrier's network when the SIM PIN locks. You will need to get
the PUK code from Tracfone. Contact TracFone customer care at 800-867-7183 for
the correct code. You can contact customer care from the phone with the locked
SIM card, but it's best to call from another line so the representative can
walk you through the process of entering the code.
Entering
the PUK
Enter
the PUK code on the prompt screen with the dial pad. PUK codes are eight
digits. On some TracFone handsets, the phone will immediately ask for a new SIM
PIN as soon as you enter the PUK code. On other handsets, you must change the
code manually. Check the "Settings" menu under "Security."
Some LG phones have separate settings for the SIM PIN and handset lock, so make
sure you choose the correct lock.
WHAT TO WITH
THE PUK CODE
Once you have got the PUK code from your network, you will need to
enter it into your phone. A notification will usually pop up, prompting you to
enter the PUK code as soon as you turn your mobile on, so just follow the
instructions on screen to
proceed.
As soon as your phone is unlocked, you may be asked to enter a new
SIM PIN number, but this can be turned off in the settings menu of the phone
once it's fully unlocked.
WARNING: Do not try and guess your PUK code. If you
enter it wrong 10 times, the SIM card will be permanently locked and you will
need to get a new one from your network provider. There may be a charge for a
new SIM card and you might be stuck without your phone for a couple of days
while they send it out.
