SM-935S: Korean version compatibility with T-Mobile USA?

[hasasimo]

I'm having a Korean version of the S7 Edge (model SM-935S) shipped my way. I'm on T-Mobile USA and it seems the LTE bands are fully compatible. But only the refarmed 3G bands (1900), not AWS (1700/2100) will work. I have no idea if my area (northern Virginia) has been refarmed).

Do you think I'll be missing anything? What will work and what won't? How about Samsung Pay?

Thanks!
