"Verizon customers will be the first in the world to have the power of 5G in their hands", said Hans Vestberg, Verizon's chairman and chief executive officer.
The new network is predicted to drive technologies such as self-driving cars, augmented reality, VR and "smart cities", where sensors help cities to monitor everything from pollution to traffic.
The carriers say 5G-enabled smartphones are capable of downloading data 20 times faster than existing 4G devices, which in theory would enable users to download movie files nearly instantly.
South Korea has claimed it beat the United States by a matter of hours to become the first country to roll out a super-fast 5G mobile network, which allows users to download entire moves nearly instantaneously.
But South Korea's government says Korean companies launched their services for some customers before Verizon. In the USA, meanwhile, Verizon has claimed a world first by launching in parts of Chicago and Minneapolis on Wednesday, a week earlier than planned, also with a single device - a 5G clip-on module for its Motorola z3 smartphone, available to prospective customers.
SK Telecom and two smaller carriers had planned to initially launch 5G in South Korea on Friday with Samsung Electronics' new 5G-enabled smartphone Galaxy S10.
The network is expected to rake in some $565 billion in global economic benefits, according to London-based Global System for Mobile Communications, an industry alliance.
It has a total of 27 million users. "5G provides a chance for South Korea to take a leap again".
The implications of the new network have pitted Washington against Beijing - whose firms dominate 5G technology - in an increasingly bitter standoff.
