There is nothing to sY you can buy an international version or unlocked one here.
There is a lot to think about with an International version. First there are some issues popping up with them, Samsung has halted shipment.. I wouldn't get one now.
Also you have to really make sure you get the right one for using towers here. Some people have issues with LTE.
There is also the matter of Samsung support. You don't get Samsung support or Samsung warranty if you buy one. Samsung USA won't support an international model.. Not unless they have changed that on the last year.
Thank you!
I didn't realize the halted shipments were for the international versions, I figured it was for the currently ordered devices waiting to be filled.
My Passport was an unlocked/international version, and I had no issues with LTE on AT&T. Still on AT&T with the Note7 using the same nano SIM and no issues as far as I can tell. The halted shipments is definitely something to be concerned with, and the same with the warranty. I'm currently using Best Buy insurance on this since thats where I got it from.
