Last year, Windows Phone was in fourth place in Latin America, but has grown sharply over the last year. On a sequential basis, the platform grew 12% from the first quarter. The Nokia Lumia 520 has become the best selling Windows Phone model and in emerging markets this one device is being lauded for contributing to the strong growth of Microsoft's mobile OS in the area. The Redmond based company mentioned Argentina, Brazil, Chile, Colombia, Mexico and Peru as countries where Windows Phone is showing outstanding growth.
Nokia has been using a two pronged strategy depending on the region. In emerging markets like Latin America, the Finnish based manufacturer has been concentrating on offering low-end models priced accordingly, but with enough features to attract buyers looking for more than just a cheap handset. In the U.S. and other developed markets, Nokia has been using phones like the Nokia Lumia 920, Nokia Lumia 925, Nokia Lumia 928 and Nokia Lumia 1020 to focus (no pun intended) on the line's ability to take great pictures in low-light conditions.
