Unlocking an LG Xenon with an unlock code only takes a minute and this video will help you. The LG Xenon by default comes with a SIM lock that prevents it from working with other phone networks other then AT&T. However, using an unlock code your LG Xenon can be unlocked quite easily. Although, this video is for the LG Incite CT810, the same unlocking instruction should apply to the LG Xenon GR500. Additionally, if you want to see these same basic instructions in text, you can check out my previous unlock code here. Otherwise, enjoy this video that I found online. Hope it help and good luck unlocking your LG phone!
