I forgot the security code to my phone and i cant


YOU CAN TRY THIS ----->

You should be able to reset your LG 8500's lock code back to the last 4 digits of your wireless number by doing this:

Hit *22899 send (if this doesn't work, try *228 send, choose option #1) to re-program your phone.

Doing this will re-program your phone, and reset the default code. Once you hear the "your phone has been programed successfully" message, select OK. Your 8500 should go off and then back on again. ....... Now you can hit unlock, and enter the last 4 digits of your wireless number.

Cannot access voicemail on Motorola Razr


If your wife never reset the codes when she used the phone, the "unlock" 4 digit PIN code is usually 1234, or sometimes the service provider resets it to the last 4 digits of your cell phone's number before sending it to you.
The SECURITY code is a 6 digit code which is set to "000000" when the phone is first sent to you and since your wife never used it that should still be it. I'd try entering 000000 for the "invalid security code" message you are getting and see if that does it. Some service providers may reset that security code before sending the phone to you too, so if any of those codes don't work you'll have to call your cell phone service provider to find out the codes. This info about all the codes was in my Razr V3 manual. Hope it helps.  If that does work for you and you can get into voicemail, then to reset the codes to your own personal ones go to ....Settings > Security > New Passwords and reset them.
If you get to the voicemail message screen and the message  stored there, (it's probably a message from the service provider) you have to call the voicemail number to retrieve the message, I just  press the keypad "dot" on the top right side under where it will say "call " and it dials & brings me to my voicemail.  The voicemail number should be stored in the phone, but because it was never set up you may have to call the provider to do so, I can't remember if it was already in there or not when I first set my phone up. Anyways......Good Luck & Happy New Year ; )

The subsidy password


usualy the unlock code is a default like 0000 or 9999 or 1234 or the last 4 numbers of the social security # of the previous/current signer of the account. the 6 digit security code is usualy the birthdate of the signer on the account. if none of those work call the phone company and give them your info and they will reset the code to a default.
