Sales in Emerging Markets Help Nokia Add to Its Cellphone Lead – New York Times Nokia sold 100 million mobile devices in the period, an increase of 29 percent over 2006, while the overall industry growth was about 14 percent, with 262 million mobile devices sold globally, Nokia said. But the group again warned about the performance of its troubled network operations, describing market conditions as challenging because of heavy competition. “We shall have to increase the amount and speed of cost cutting,” the chief executive, Olli-Pekka Kallasvuo, said, giving no details. The greatest growth in Nokia’s handset sales, 37 percent, was in the Middle East and Africa, it said. But at 36 percent growth, sales were also strong in the Asia-Pacific region and in China.
