According to iSuppli, Nokia is still outselling its competitors in the mobile-phone handset market by more than two to one, and the company's market share increased from the second quarter.

The analyst firm said that Samsung remains Nokia's closest competitor. Nokia, however, controls 39.5 percent share of the market, while Samsung shipped only 15.1 percent of those phones sold during the third quarter. Motorola, Sony, and LG rounded out the top five, although iSuppli cautioned that Motorola's market share estimate should be considered preliminary until Motorola reports its earnings later on Thursday morning.

As usual, the only market Nokia has had difficulty in is North America. iSuppli analyst Tina Teng said in an email that the third-quarter sales figures for the North American market were not available yet. Through the end of 2006, Nokia had roughly 15 percent of the North American market, placing it fourth behind Motorola, with a market share of 40 percent. LG and Samsung almost tied for second and third, respectively, she said.
