A:AnswerIt comes with charger but not power adapter which you have to buy separately at cost of $15 US if you want to ever charge this watch. Otherwise, you can just use it as a very expensive show piece or a paper weight. Another way by Samsung to separate you from your money.
A:AnswerThat would depend if those features are working in your region.
In my region (non us) Samsung pay does not work, but Google pay does.
ECG as far as I know is region free, I can use in mine without an issue.
