I'm just weighing in here on this (hi, by the way!!!)..
I'm in the UK and have just bought an unlocked version, due for delivery next week.
I'll set it up using Vodafone here, but I'm actually moving to the US in a few weeks and will be using my Note 7 on whatever US mobile carrier I end up going with (probably AT&T - maybe Cricket - or T-Mobile.)
Are you confident it would be compatible with these networks? I'm also curious about Samsung Pay - it's never actually been turned on here in the UK and I don't think it even appears on the apps list as Samsung may have to enable it in a FW update. I use Apple Pay all the time, and I suppose Android Pay will lessen that sting (it's used widespread in the US, right?) but would be good to know if SP will work on my UK model in the US.
Has anyone experience of using a UK model with a US carrier? May be too early with the Note 7, but maybe an older device like the S7 or another?
Also, how would you deal with warranty? I know Samsung aren't up there with Apple in terms of ease of repairs with an international warranty, but lets say I smashed the screen.. can you get it repaired by Sammy in the US (albeit for a fee) or would it have to be sent all the way back to the UK? Are you able to insure a foreign international model or do the insurance companies refuse to help?
Any help would be great as I may need to cancel my order and just buy a US model next month - but having never had a carrier device, the thought of all of this bloatware scares me!
