My UK/European official model is an N9005 (4G, 4k video, Qualcomm quad core). N9000 asian models are grey imported here, and also to the US from what I have heard. Most all US carrier variants have a N900- tag with a letter, and from what I gather they are specced like mine. Some don't mind 3G, I am tied to it for 2 months more with a 4G phone and it's still fast; but buy a grey import N9000 with caution and prior knowledge if it's a good deal. You may have to send it to the country of origin if it goes wrong. Your local Samsung won't help you. There is a way of checking a CSC code in any Note 3 to determine the country of origin, ie where it was meant for. Also imported 4G models will need to have the correct LTE radio bands to work in your region.
Check other threads.
*BUT it seems reading the OP again you will buy locally. You must have been looking at the international models N9005 / N9000.
