Worldwide mobile phone sales totaled 190.5 million units in the second quarter of 2005, a 21.6 percent growth from the same period last year, according to research firm Gartner, as more people start to replace older handsets.

“The sales in the mature markets of Western Europe and North America were driven primarily by sales of phones as replacements for older models and, to a lesser extent, by first-time buyers” said Carolina Milanesi, principal analyst for mobile terminals research at Gartner.

Nokia and Motorola have strengthened their position in the marketplace, as the two companies accounted for almost half (49.8 percent) of worldwide mobile phone sales in the second quarter of 2005.

Motorola, sellers of the hugely popular V3 RAZR phone, was the second best-selling vendor in Western Europe, a significant improvement compared to the same time last year when Motorola finished as the No. 5 vendor in the market.

In the North America, Motorola was the market leader with its share reaching 33.5 percent, while it was the No. 2 vendor in Latin America with 31.9 percent of sales in the region.
