Let me give you a little background and then some solutions. This is generic because I don't know your carrier. I'm useing ATT as an example.
Phones are naturally unlocked, but a service provider might lock them
When originally manufactured, all GSM cell phones are unlocked. That is, they can be used with any SIM from any cellphone service provider - always assuming, of course, that the cellphone service provider has compatible GSM service on the same frequency bands that the phone can operate on.
Most cell phone service providers electronically 'lock' the phone so that it can only be used with their service. There are obvious reasons why they choose to do this - in particular, to force you to pay what are usually very high roaming charges when you take your phone out of their network and use it elsewhere in the world.
Fortunately, this locking is reversible. With some phones, it is possible to simply enter an unlocking password code into the phone and it is immediately then unlocked. Other phones need to be connected up to a special unlocking data terminal.
Your phone has to be unlocked by the carrier. LG, Motorala, Sony Ericsson, Nokia and most of their ilk, will not give consumers the unlock codes but don't despair.
A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from your carrier. For example, if you have AT&T to unlock your SIM card, you can obtain your phone's PUK code from AT&T by:
? logging in to your myWireless Account online ? using their Technical Support Chat ? calling Customer Care at 1-800-331-0500
To get your phone's PUK code online from ATT:
? Log in to your myWireless Account. ? Select My Services under My Account. ? From the My Services screen, select My Phone/Device. ? Select Unblock SIM Card. ? The Unblock SIM screen will display your PUK code.
Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code.
Note: If you enter the wrong ATT PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator."
There are three other ways to unlock a phone:
? The carrier will unlock the phone for you at one of its retail outlets; ? You can do it yourself by clicking on this link Free Unlock Codes , ? Pay $3.89 at the following website: www.theunlockshack.com/.
I trust that this is helpful and solves your problem. All the best
You can find the PUK code is in your SIM card documentation Starter Pack. If you do not have this then contact your phone service provider. Your cell phone service provider can give you the PUK code once they have confirmed your identity to prevent any stolen SIM access.
How To Unlock Your LG Viewty KU990
1. Boot up your LG Viewty phone with the original SIM card in. 2. Bring up the LG Viewty keypad on the screen. 3. Now type, 2945#*990#. 4. Next, a menu will pop up and select SIM unlock. 5. Enter your unlock code. 6. Your LG Viewty KU900 should reboot automatically and your done!
And now you have yourself an unlocked LG Viewty mobile phone. If you do not have an unlock code, you should probably try to contact your phone carrier first. Many websites suggest paying for an unlock code, but I feel this is unnecessary.
Note: The free unlock instructions provided on this site only work with GSM or SIM card versions of the LG Viewty KU990. As always there may be already unlocked versions of this mobile phone, but generally cost a lot more then unlocking it yourself.
What should I do if my iPhone says
error P1246? Answer:
A PUK code (Pin Unlock Key) is required when you enter an incorrect PIN 3
times. After entering the wrong PIN 3 times, the card will be locked and
you will need to get a PUK code from your service provider to unlock it.
Unfortunately only AT&T can generate a PUK code to unlock the phone for you. It is impossible for us to create a code for your phone, it has to be done through the service provider. However this is a free service they offer. Call them at 1-800-331-0500
If the wrong PUK code is entered ten times in a row, the SIM card becomes invalid and you will need to purchase a new SIM Card. The phone will display "PUK blocked call operator".
no it just unlocks it from you putting a wrong passcode in you need to take it to a local phone repair centre i was charged £10 the phone was £30 cheaper on a different network so i saved £20 but not all phones will work on all networks (im led to believe) hope it helps ej
stands for 'Pin Unlock Code', and has to be entered if you've locked
your SIM by repeatedly entering the wrong PIN code. If you're asked for
a PUK code, you've had more goes at guessing your SIM card PIN code
than you're allowed. You'll need to phone your network provider
Customer Services for your PUK code to unlock the SIM. For security
reasons, it's only the network operator that can legally provide you
with a PUK code to unlock your SIM.With some phones you will get a cert card with your sim card and it might have the 8 digit PUK on it. if this has been entered 10 times or more incorrectly then you will need a new sim card
