We'll soon be testing AT&T 3G out here in the weeds... I get no bars on Verizon, Tracfone or Net10 where I live, but the business rep for AT&T says they put a new tower in my general area .. We'll see?!
Just in case the trees will be an issue, I got one of those external antenna boosters that creates a wifi in your house. We can only get dialup because there is no DSL.
