Default Pin & Security Codes for SIM cards

A number of networks still use a default pin on their SIM cards at the point of dispatch as a security precaution. If you lose or forget the PIN code it can be irritating.

Please note these PIN's will only work if you have NOT changed the default PIN. If you enter the PIN code incorrectly three times, a lock will be put onto the SIM card, and you need a PUK code to unlock it.

You can obtain your PUK by contacting your network service provider.

Default Network PIN Codes:

O2 = 0000/4321

Orange = 1111

Vodafone = 0000

Fresh = 1210

Virgin Mobile = 7890 / 1210

Vodafone = 0000

Talkmobile = 0000

3 = 0000

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.

Security code Nokia 3110 classic


SIM pin code:
This is a pin code that locks the sim card until you enter the correct code. This protects your account, even
if your sim is put into another handset. To reset it, you need the PUK code:
Pin Unlock Code (PUK)
If you miss key (or forget) your SIM pin code, and enter the wrong one 3-5 times in a row, the SIM will lock up, and you’ll need to enter the PUK unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don’t try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled.
Phone Security Code:
This locks the handset, as opposed to the sim card. You can also set some handsets to only accept a “new” sim if the phone security code is entered. To reset it, you need the Master code code:
Master Reset Code
Sometimes known as the Master Code, this allows you to unlock a handset if you have entered the Security Code wrongly too many times.
Which is the one that you want?
The default security code for Nokia is 12345

forget my nokia n73 lock code


If you need the SIM Pin number to switch the phone on, then you have to enter any Pin number 4/5 times, then the phone will request a PUK number. This number was on the plastic card that your SIM card was attached to. If you don't have it, only your Network Service Provider can supply it to you.

If it's the Security code you need, to get into certain settings IE. Erasing received calls, missed calls, timers etc... The Nokia default is 12345 if you didn't change it, but if you did change it and you've forgotten it, let me know, I'll tell you how to retrieve it.

The IMEI number doesn't have anything to do with the SIM Pin number. It is used to identify, track, and Blacklist your phone.
