Strategically integrated the two previously separate SK Telink sites—the corporate introduction, international calls 00700, and 7Mobile budget phone sites—to strengthen the SK Telink brand and enhance its role as a marketing tool. The business reinforcement of budget and value prepaid phones and the provision of diverse country-specific information for international calls 00700 were developed with a focus on user convenience. To improve user accessibility, both mobile sites and PC modes, which were not previously provided, were offered, and a user interface and design were implemented that enhance the aesthetic aspects optimized for each device and leverage strengths in information delivery through a clean layout. Established a quick menu configuration as a personalized area to provide a user interface that enables users to quickly navigate to desired menus at any time. Configured menus to meet the needs of the company’s offered menus and users interested in budget phones and international calls, allowing customization at any time. Provided linked content between pages so that moving to any page within the site is easy, enabling users to continuously surf various information on the site and naturally access the information they want, thereby maximizing the user experience.
