Hello! I'm considering buying an iPad but I'm worried about the 4G LTE. The thing is that they always over-price iPads in my country but I'm lucky that I'm visiting USA next week so I could buy an iPad 2x cheaper. But... Mobile operators support 4G in my country so that isn't a problem. But will it work? I see only At&T and Verizon iPads. Can someone help and explain to me what should I do?
