There is no such thing as a ‘within US only’ unlock. It’s either locked to a specific network or will work worldwide

Since this one says it’s unlocked it will work worldwide

If it’s shipped and sold by Amazon then it’s very likely new, I say go for it. I wouldn’t buy from 3rd party sellers on Amazon for big purchases like that unless it is also Fulfilled (shipped) by Amazon, as that makes returns much easier (and shipping reliable). “Like New” is usually the best you can find, sometimes the device is unopened and the box has a dent, or it was opened but saw no real use. If it’s a like new refurb tho then it’s possible the phone was a daily driver for a while. If you do buy it check the battery health percentage. If it’s below 95%, then I’d reconsider keeping it. I recently bought AirPods and had the same labeling thing with Used -> vs. refurb premium. In most cases your assumption that a “Used - Like New” = open box is correct, but not always. Good luck! The labels do not always make sense but I’d say it’s worth a shot if it’s fulfilled by Amazon. More on reddit.com
