T-Mobile launched its 5G service in six U.S. cities over the weekend: Atlanta, Cleveland, Dallas, Las Vegas, Los Angeles and New York.

All four of the country's major carriers now offer 5G.
The ultra-fast network can be accessed on the Samsung Galaxy S10 5G, which retails for $1299.99. The phone can access T-Mobile's LTE network in areas where 5G is unavailable.

In a statement, T-Mobile CEO John Legere said the company's network would be "broad, deep and transformational." With the company's proposed merger to Sprint still pending before the government, Legere said approval would mean the combined companies could build "the kind of 5G network America deserves."

With this launch, every major U.S. carrier now has some sort of 5G on the map, and each has talked up big plans to expand (Verizon also brought their service to Denver and Providence, RI last week). Although it's still early, the 5G adoption from major cities marks a positive trend that should keep the U.S. on pace with other countries.
