Samsung Electronics today released the Galaxy S10 5G, the world’s first available smartphone with built-in fifth-generation communications technology, as South Korea seeks to build a lead in the transformative system.

On Wednesday, the South became the first country to commercially launch nationwide 5G services, with three super fast network going live offering data speeds that allow users to download entire movies in less than a second.

Hours later, US giant Verizon began commercial services in Chicago and Minneapolis, after rival AT&T made a 5G-based system available to selected users in parts of 12 cities in December.

South Korea’s three mobile carriers, SK Telecom, KT and LG Uplus, held launch events across Seoul for the Galaxy S10 –  the base version costs 1.39 million won (US$1,200).

This is according to an online magazine based in South Korea.
