Sony Ericsson is a joint venture that was established in October 2001. The two companies decided to work together to combine the expertise they had in consumer electronics and telecommunications. As a result they gave up work on creating their own mobile phones to come up with the Sony Ericsson mobile phone models that has made the new company the fifth most important world manufacturer of cellulars.

Beside the highly praised and really good Sony Ericsson mobile phones, the company is also well-known for its other products in the field of electronics such as wireless voice devices, hi-tech accessories, wireless data devices, wireless systems, mobile music devices, noise reduction headset and noise cancelling headphones. The Sony Ericsson mobile phones that sent the company on the way to its great success are those in the Walkman and cyber-shot series. Candy bar phones are also very popular besides the Walkman and the cyber-shot designs.

Sony Erricson mobile phones are great for all categories of users regardless of age, gender or social status. They look sleek and stylish, but they also meet high operational standards. In addition, their interface which is intuitive and user-friendly together with their very reasonable prices add up to their popularity. Many Sony Ericsson mobile devices are sliders, and their colorful availability allows users to choose according to personal preferences.

Mobile phones are now more special because of the business facilities, the music options and the design that come at very cheap rates. Actually the five largest Sony Ericsson mobile categories are: the Walkman-branded W series music phones, the Cyber-shot  branded line of phones, the Xperia range of mobile phones, the UIQ smart-phone products, and the BRAVIA-branded line of phones.

The Sony Ericsson mobile phones that belong to the Walkman series were issued in 2005. They marked a great innovation moment because of the music-centric features unavailable with other phones. The Cyber-shot phones were produced in 2006 in newer models in the K series of phones. These rely on the quality of the auto-focus camera incorporated in the phone. The UIQ smart-phone mobiles are famous for their touch screens, QWERTY keypads and use of the UIQ interface platform from Symbian OS.

The mobile phones in the Xperia range got public in February 2008 at the Mobile World Congress that was held in Barcelona. This telephone opened the way for the integration of the Windows Mobile Operating System for the Sony Ericsson powerhouse smart-phone. Finally, the BRAVIA line of  Sony Ericsson mobile phones was launched on the Japanese market in 2007.
