I'm going to be in the States for work, for just over a month. I'll be in Washington DC, Iowa, Chicago, and New York. I'll have my iPhone 4 with me, and a tablet/netbook convertible, which I'd like to be able to tether to my iPhone for internet access from time to time. I've been told that wifi access will be reasonably prevalent, but to be on the safe side I'd like to have a 3G data plan on my phone so that I can stay in touch with my wife back in NZ via Viber and Voxer/Skype. I won't have much need to txt or call anyone in the States.
I've been told that Verizon is probably my best bet, as it offers the most reliable coverage in Iowa (where I'll be for two weeks), so I'm leaning that way. They have a 99c/day pay-as-you-go option, which seems to just deduct 99c from your top-up credit whenever you use the service. This looks to be the best value, as I may not need it every day if the wifi coverage is as good as it sounds.
I've looked through Verizon's website, but I haven't been able to find out how to get a micro-sim for my iPhone. I presume I can just walk into the store and get one, but I'd like to know before I go over there. Does anyone know if this is right? Or is there a better suggestion than Verizon? I would ask Verizon, but bizarrely there doesn't seem to be a simple email address for queries...
