Most things lose support when you cross borders. So check with Sam if they do the usual.

I want to share why this is. It's really simple.

You bought it in some country and part of that sale went to the support in that country. Now a newbie may exclaim Samsung is a global company and be right but be unaware that countries do not allow a global company to most money around the globe freely.

So your support is in the country of purchase. Simple.
