Micro,
You are most welcome sir.
Here are ALL of the frequencies your LG phone can use.
The CDMA camp now has SIM cards while the GSM camp does not support CDMA - they do support LTE and the LTE bands are numbered to help make it easier to identify bands used. I was a B2B rep with AT&T and I kicked Verizon and the CDMA camps butt because mahogany row traveled internationally and that = GSM. I also loved being able to pop my SIM card out and put it into any other GSM handset and was up and running in seconds.
