China, Spain and France highlighted as the highest overseas adopters.
Samsung has now shipped five million units of the 5.3 inch Galaxy Note 'phablet' in five months. It hit one million after two months on the market.
The Korean firm says that China, Spain and France contribute the largest share of purchases in its overseas markets, while sales were on the rise in Germany, Hong Kong and Taiwan.
Korea was responsible for the majority of the device's success however, accounting for 67 per cent of worldwide shipments.
Last month, Samsung's flagship Galaxy S II phonereached sales of 20 million in ten months so it seems the Note has some catching up to do based on that figure.
