Which of these plans is the least-limited version of "unlimited"? I've already discovered that Verizon won't offer their plan for 4G access points (even though I can buy a five year old sacrificial phone and tether to it 24/7). AT&T apparently doesn't allow tethering at all (which I thought the FCC had previously spanked them for, but, no surprise they went for a "Hail Mary" pass after this past January).
So, which of these plans really will let you use it as close to unlimited as possible? I have no delusion any of them will actually give me the upper possible limit of a solid 42.8Mbps for 13TB/month, but will any even realistically let me use 3-5Mbps sustained for a few hours a day, with 50+GB/month total?
