I use a Verizon aircard while on the road. I signed up in July and signed a 2 year contract. Didn't really want to, but I got the aircard free and free activation, so I guess it all comes out even in the end. Where we are in Illinois, I do not get broadband, but am on "national access". It is not as slow as dial up, but not as fast at dsl. I'm at home in Texas right now and it is faaaaaast!
BTW, I am on the internet a LOT and did not even come close to going over the 5g. I don't dl a lot (because of speed), either.
