I changed sim cards and the phone is still locked I am using a

sim cards are PUK and pin code specific
by changing sim cards , the system sees it as a stolen phone and locked it out of use
call vodafone or go to a vodafone shop to sort out the problem

is it a post paid plan or a prepaid sim?if it's the former, i suggest talking to your service provider about it.if it's the latter, just a buy a new one from any retailer. ^_^

PUK Codes

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 AT&T to unlock your SIM card.

Since I don't know the name of you carrier, I'm using AT&T as an example. Most carriers use the same methodology though the wording may be different.

You can obtain your phone's PUK code from AT&T in one of these ways:

• Log in to myAT&T online
• Use our Technical Support Chat.
• Contact Customer Care


To get your phone's PUK code online:

? Log in to myAT&T.
? From the myAT&T tab at the top of the page, hover over the Wireless link and select Phone/Device under the My Wireless Service heading.
? From the My Phone/Device screen, select the Unblock SIM Card link under the My Make & Model heading.
? The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card.

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 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."

You can also do it without any assistance from anyone, However, be sure to read the following carefully because there are pitfalls.

Although most people remember their primary SIM PIN code, those other codes - used for various verification purposes - are never to be found when needed. Below we've included a set of short codes which, when entered on a handset's standby screen, will let you easily change PIN and PUK (short for Pin Unlock Code) codes - but keep in mind, they may not work with all handsets and mobile operators. If you are interested in a software fix, click on the following link: Universal SIM Lock Remover

More importantly, when changing ones PUK codes there'll be no help to get from the mobile operator if the new codes are forgotten, so make sure to write any changes down alongside the old PUK codes. Also, please note that the codes should be entered without the spaces shown below.

Change SIM Card PIN
** 04 * old PIN * new PIN * new PIN #

Change SIM Card PIN 2 (Write down the new code)
** 042 * old PIN * new PIN * new PIN #

Change SIM Card PUK (Write down the new code)
** 05 * old PUK * new PUK * new PUK #

Change SIM Card PUK 2 (Write down the new code)
** 052 * old PUK * new PUK * new PUK #

Hello there,
If your phone is not accepting any other sim card, then it means the phone is sim card secured lock or protected, there are some phones that do not accept any other kind of sim card apart from that which they are made for.
For instance a phone made for vodafone purposes cannot accept etisalat sim cards, it will only accept vodafone sim card. Therefore that is what you are facing with the phone.
Take not, if you insert similar kind of sim you were iniially using, it will accept it.
That is why you cannot use another kind of sim on the phone.
Thank you for using fixya Caseytech

Typically when you purchase a cell phone, the company that sold you the phone (ex: AT&T) 'locked' the phone before you bought it, so you can only use it on their network. This means that you can't use your phone if on any other network, even if you change the SIM (which is an abbreviation for Subscriber Identity Module) card. The SIM card is the little piece of plastic that identifies your phone to the cellular network. Changing your SIM card to have your phone work on another network is useful especially if you want to travel to another country and want to buy a pre-paid SIM card so you can have cell phone access without roaming charges. There are services that offer to provide unlocking capabilities for a fee, but don't pay for them! You can do it yourself for free, which is the perfect price.

Hi,


It seems you encode a wrong sim card password?

PUK means "personal unlocking key" .

The PUK code is asked if you enter a wrong pin 3 times.

You need to call your phone service company, they can retrieve the puk code from a database
for free.

In your case you need to contact your SIM card phone provider technical support to unlock the SIM.


The PIN and PUK are related to the SIM card, not to the phone.

If you replace the SIM card with a different one, then the phone should not ask for the PUK anymore.
thanks,

Securing your Shine
Secure your LG Shine and your account from thieves by locking your phone and your SIM card Losing a phone through accident or to a light-fingered thief is annoying, frustrating and potentially very costly, especially if the 'finder' uses your SIM card to make expensive calls. You can, however, lock both your phone and your SIM card with four-figure PIN numbers to prevent unauthorised use.
The first line of defence is to set a SIM card PIN. This means that whenever you turn on your handset you have to enter a PIN code before the SIM can be used. The default PIN code for your SIM is dependent upon your network; usually it will be found in a small booklet that came with the SIM card.
The PIN can be enabled, disabled or changed from the Security menu – but you only get three chances to enter it correctly. After those three, the SIM will get locked and can only be unlocked by entering the PUK (PIN Unlocking Key) which your network can give you. Enter the PUK incorrectly 10 times, and the SIM will be irrecoverably locked.
To activate a PIN code request, open the main menu by clicking on the scroll wheel. Click 9 to access the Settings menu and click 6 to enter the Security menu. The first item is PIN code request - click 1 or OK to open it. By default this will be set to off. To activate a PIN request, click 1; you'll now be prompted to enter the four-digit PIN. When you've done this, click OK, and if the pin was correct, you'll see the confirmation message 'Complete'.
To deactivate the PIN code request, you would simply select Off from the menu by pressing 2; you'll need to enter the PIN code whenever you change this setting.
PIN code request prevents another user from using your lost or stolen SIM card in their own phone. To lock your phone, and thus render it useless to a thief, you can activate Phone lock.
Two levels of handset locking are available. The first - called 'When power on' in the Phone lock menu - is to require an unlock code to be entered whenever the handset is switched on. This can be confusing and irritating when used together with the SIM PIN, so a second option is to only request the handset unlock code when the SIM card has been changed - called 'When SIM changed'. This means that if your phone is stolen, the thief can't use their own SIM card in it as the phone will need a PIN code to unlock.
To activate either option, go to the Security menu (clicking 9 for Settings and 6 for Security from the main menu) and click 2 to enter the Phone lock menu. Click 2 to activate When power on or 3 to activate When SIM changed. In either case you'll be prompted to enter the security code. By default this is 0000. Enter the code and click OK to confirm.
To change either code, go to the Security menu again (clicking 9 for Settings and 6 for Security from the main menu) and click 5 to enter the Change codes menu. To change the handset's security code, click 1 to select Security code, or to change the SIM PIN, click 2 to select PIN1 code. In either case you'll be prompted to enter the old code before entering the new code twice, clicking OK to confirm each time.

This means that your phone was set to 'lock upon sim change'. You would have to insert the old sim card and go to your security settings and change this, then you can use your new sim card.
