I purchased this device while they still had new devices in stock. I would assume the Showroom model it slightly used but would be like new, so in a factory box but opened. Mine was new and sealed however. These are unlocked devices so can be used with any SIM card. So any GSM provider in the US should work with as well. On a side note, if you travel a lot best plan I've seen if the World plan with Sunrise that will give you unlimited coverage in CH, EU and US (I have this plan).
