Hi I need to unlock my LG KG800. It is currently set to Virgin and my sim card that I want to use is O2. How do I do this. I don't want to pay

CHECK IS THAT CDMA OR GSM MOBILE!

1) if it is CDMA , you cant insert sim.
2) if it is GSM , YOU have to unlock that and then you can insert other SIM.

CHECK UR MOBILE MANUAL(CATALOG) TO KNOW THE PORT WHERE U CAN INSERT THE SIM.

Do you mean unlocking the phone screen (like you forgot your security password), or unlocking the phone to use a SIM from a different network?

To Unlock the Phone from the Network lock use the Unlock code,You can get the Unlock code from here Wickedunlock.com
and Unlock it step by step using the instructions below:

if a phone was purchased from o2, like this one, they subisdise the value of the handset, so in which case lock the phone to there network best thing to do is go to a market to get that unlocked for around £5 english money, failing on that contact o2 and request one
