IMPORTANT! DO NOT ORDER CODE FOR CDMA PHONE!
If your phone is from Sprint, Virgin Mobile USA, Verizon, Boost, Tracfone... DO NOT ORDER UNLESS YOUR PHONE PROMPT FOR AN UNLOCK CODE.
Switch ON your phone with a SIM card from a different carrier (insert a non-Accepted SIM Card in the phone): IF the phone prompt / ask for an unlock code: it's OK, you CAN ORDER.
If phone DOES NOT PROMPT/ASK FOR UNLOCK CODE: DO NOT ORDER. That means your LG handset has a factory firmware that does not allow you to unlock it with a code.
