Mobile Phones
Nokia's Mobile Phones division provides the general public with mobile voice and data products across a wide range of mobile devices. The division aims to target primarily high-volume category sales of mobile phones and devices, with consumers being the most important customer segment. The devices are based on GSM/EDGE, 3G/WCDMA and CDMA cellular technologies.

Nokia believes that design, brand, ease of use and price are mainstream mobile phones' most important considerations to customers. Nokia's product portfolio includes camera phones with features such as megapixel cameras and MP3 players which appeal to the mass market. In the first quarter of 2006 Nokia sold over 15 million MP3 capable mobile phones, this means that Nokia is not only the world's leading supplier of mobile phones and digital cameras (as most of Nokia's mobile phones feature digital cameras), Nokia is now also the leading supplier of digital audio players (MP3 players). Nokia aims to sell 80 million music phones by the end of 2006, outpacing sales of devices such as iPods from Apple.[6]
