My lg extravert is almost 5 yrs old. I don't think the battery is going to last much longer, so I found the exact same phone (brand new) on eBay and just received it. Can I take the SIM card out of my old phone and use it in the new phone? I hope I can still use the lg extravert on Verizon Prepaid plan. Does anyone have this phone and using it on the prepaid plan?
