SK telesys is the only IT device manufacturer within the group that has core competence in the
R&D and marketing of communications equipment, such as repeater, transmission equipment,
Mobile WiMAX and end-user devices such as cell and VoIP phones.

SK telesys started off in 1997, operating businesses involved in setting up B2B based
communications infrastructure such as repeaters and transmission equipment. Its value was
recognized for providing optimized solutions to communications businesses, using its top class
technology products. SK telesys is now expanding its presence in the market as a professional
communications business. It became the second in the world to commercialize the Mobile WiMAX after Samsung.

In 2009, SK telesys produced its 1 millionth VoIP phone for SK broadband, and also successfully
launched the first Korean SNS full touch-phone “W”, which has an emotionally intuitive user
interface. SK telesys was able to diversify its business portfolio from the existing B2B business
into the consumer products market, and is expanding its points of contact with customers through
various platforms. By building a strong brand through the launch of “W”, the high-quality emotionally interactive mobile phone, and the communications equipment optimized for the wire to wireless convergence environment, SK telesys will become a total IT equipment producer – creating an innovative communications environment that caters to all our customers’ needs.

From 2013, SK telesys phone business has been diversified to ODM basis. Based on accumulated design capabilities and skillful engineers, SK telesys is ready to bring new wind to the low-priced ODM phone market lead by Chinese makers.
