I'm considering buying an unlocked international version of the pink gold 64GB Note 5. I've never bought an international version of a phone before, so I'm not sure if there's anything I should be aware of beforehand that might surprise me. I've got AT&T, so it should work, but I'm a little worried about spending several hundred dollars on a phone off of eBay and then getting burned. I already know that I'm either going to have to cut my SIM card or buy a new one (I currently have an S5), but I don't want any nasty surprises.
