Verizon has lte for pretty much all of the big cities in GA, and quite a few beyond. 3g everywhere else. At&t has better north ga coverage with 3g, but verizon is pretty much even IN LTE COVERAGE when taking in account the other areas that at&t doesn't cover. And that's at&ts 3g, at&ts lte is even lower in coverage and will probably stay that way.
Go out of the cities and you get edge crap with at&t. And edge crap for at&t is usually 600 ping 100 kbit d/50 u crap.
