I have a LG BL20 New chocolate,and i dont know my security code for messages. Can somebody tell me how to remove security,or how to found real code? Please,it is urgent

You can buy the unlock code from ONLINE site,you can get the network unlock code from here Simpleunlocking.com
and get the Security unlock codes from service provider.

Sorry we have no way to know your security code.

It's 100% safe, 100% accurate and backed by money backguarantee.

Hope this will help.
Thanks.

Hi - mine did the same and several calls to their helpline later, I think I've figured it out! Go to Settings, Profiles, and you get a list of what rings you want. Whichever one you want, select it then press Options, and then Personalise. Scroll down and number 7 says Hourly Signals. Select 'Off'. That seems to have sorted mine - hope this helps!

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.

If you have AT&T ;

Sorry to inform you but it sound like your SIM is now locked .. Here is some info to help.

please take the time to review my advice and be kind and leave a feedback rating it helps me too.

You can receive your phone's PUK code from AT&T, either by logging into your account at myWireless Account, visiting our Technical Support Chat, or by calling Customer Care at 1-800-331-0500.

Once your PUK has been received, it will need to be entered into your phone to set a new PIN code.

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".

You can unlock LG BL20 chocolate at http://www.fastgsm.com/en/lg/lg/bl20-chocolate/unlock-code-usim-locked

It should be the last 4 numbers of your cell phone (unless somebody changed it). When your phone gets programmed, that's the default lock code.

or
try this

in general you cannot unlock a CDMA phone.
if you are talking about the KG800, then you can go to a site such as gsmliberty.com and get an unlock code there

Dial *4357*4357 and then that should give you the phone number and then just use the last 4 digits to unlock it

you should reach a nearby mobile shop which is an autherised dealer of lg phones.they will tell u the code
