A:AnswerNot to be insulting but, did you mean Georgia the state or
Georgia the country? Regardless, it connects to CDMA carriers
either Verizon or Sprint networks here in the USA. As for abroad,
I haven't a clue; sorry.
A:AnswerYes, at the bottom of the website there should be a "trade-in calculator" tool.
As for specific trade-in deals for the S6, probably not going to happen for a few months. Right now carriers are offering free S6s to new customers.
A:AnswerYou have to pay Best Buy the tax up front for the full amount of the cost of the phone (around $50). Then your monthly payments towards the phone itself will begin to appear on your Verizon Bill.
A:AnswerThe back is fairly slick... that being said, I would definitely be sure to have a durable protective case on this phone, which will not only help with the grip, but also protect your investment from most mishaps.
