Nope sorry. First of all Metro uses CDMA network which means their cell phones don't use any sim cards. A T&T uses GSM network and requires their cell phones to use sim cards. So your LG phone won't be able to use on Metro.
Verizon and Sprint uses CDMA network like Metro. So if you have any Verizon Wireless or Sprint phone then Metro will be able to flash it (change its software on the phone) so that it will work with Metro. There will be a small fee to flash any Verizon or Sprint cell phone. Just bring any Verizon or Sprint phone to any nearby Metro store and they can do this for you.
