With 5G reshaping the smartphone market, 5G security needs to keep up. Almost one in three smartphones sold in the first quarter of 2021 can connect to a 5G network. That’s just one year after the world’s first commercial 5G network emerged in South Korea. Such growth helped annual shipment numbers of 5G-enabled smartphones exceed 200 million units in just one year. That’s four times as long as it took 4G to reach the same milestone. With that growth comes risks, too.
