As the market leader in the ICT ecosystem, SK Telecom has spent the past three decades to lead in the field of mobile services. The Company is the world’s first to commercialize CDMA, CDMA 2000 1x, CDMA EV-DO and HSDPA networks – some of the revolutionary concepts in the history of wireless communications. It has more than 29 million mobile subscribers, which account for around 50 percent of the total market.

SK Telecom through T.um attempts expand on its mission to serve a greater role in the community by changing the social infrastructure and influencing the future lives of ordinary people through next generation technologies. This also coincides with SK Telecom’s corporate philosophy which attempts to create new values across industrial boundaries by practicing “innovation.”

SK Telecom goes beyond simply producing and selling products to consumers; instead the company provides ICT services that are not often visible or tactile to human senses. Thus the company decided to create a narrative to illustrate how ICT companies can offer invisible services that can communicate with consumers. As a result, visitors to T.um serve as an active participant of the narrative and experience the future technologies and social phenomena related to natural disasters, bio-technology, environment and transportation using ICT platform. Instead of viewing the exhibition from a third person standpoint, the show encourages visitors to directly experience the future society from the first-person point of view.

T.um envisions future development of ICT technology in the next 30 years. The exhibition space is equipped with state-of-the-art devices, and designed to avoid creating a rigid space that simply lists technological inventions in a linear fashion. In particular, the designers of the space considered public interests of SK Telecom's telecommunication technology, particularly its cutting-edge 5G technology, the world’s leading technology, as well as its commercial interests. Thus, the designers mimicked the style of a musical or a film where visitors can experience the show with a docent who serve as an actor based on a set storyline. The exhibition aims to enhance the involvement of visitors and allow them to become part of the narrative and experience the exhibition.

The museum, a collaboration by a team of designers, neurologists, architects and futurologists, has been carefully designed to offer and create an interactive ICT experience for visitors, using AR, VR, hologram and 5G technologies.

Visitors are led to enter the exhibition space at T.um through the lobby at SK Telecom headquarters to increase accessibility and make a strong impression and deliver positive image on the company for business partners and VIP guests who visit the space.

Since SK Telecom is aimed at mediating the values of communication through ICT technology, the company wanted to highlight a sense of connection with future through light when the audience enters the space. The designers and architects of the space used a lot of curves to allow visitors’ viewing experience as natural as possible, and used light-responsive materials such as mirrors and finishes while minimizing joints to allow natural flow.

SK Telecom's wireless communication services are important for consumers and the country’s technological infrastructure. T.um is also a frequently-visited spot for the foreign dignitaries hosted by the Ministry of Foreign Affairs, since the space allows visitors to directly experience the future of mobile technology. In fact, the results for such visits are substantial. Since T.um was set up, SK Telecom managed to attract many diplomatic bureaucrats to the exhibition space.

More importantly, it explores the ways in which technology could be used to achieve democratic ideals of a contemporary society by connecting rural communities and enhancing the lives of people in undeveloped areas. One of the Company's most important CSR missions has been to bridge the digital divide and resolve information gap. As an extension of their concept, part of T.um’s VR and IoT exhibition has travelled to primary schools in rural areas around the country
