Verizon, because I'm in their LTE coverage areas. They have the best and most aggressive LTE deployment and pride themselves on network stability. I also have a 4G Android and it tethers faster than my Comcast connection.
whenever I drive thru NC,SC,GA ATT is pretty spotty. alot of the time i have no service or if i have service its like 1 bar and super slow.
Oh really? I drove from Oklahoma to Florida last summer down the coastal highway and I didn't have any problems! Interesting.
