According to the Yonhap News Agency, preorders for the new Samsung Galaxy S10 lineup are slower than its predecessors. Industry sources say only 140,000 Galaxy S10 units have been sold on the first day of preorder availability. "The number of Galaxy S10's first-day registration falls below that of the Galaxy S9's 180,000 units released in March 2018 and the Galaxy Note 9's 200,000 units launched in August, they noted." The preorder registration period started four days in advance of the official launch of the Galaxy S10e, S10 and S10+. Samsung says an additional 40,000 phones have been sold without carriers' contracts and claims this places the total sales figure at 180,000 units. As Samsung plans to launch Galaxy S10's 5G model later this month and release its first foldable device supporting 5G networks in mid-May in the local market, consumers are seen to be taking a wait-and-see approach for the new flagship smartphone, industry officials said. Consumers who activate their phones by replacing USIM cards on their own are not included in mobile carriers' plan.
