On June 28th, T-Mobile will have the Samsung Galaxy S10 5G for sale. They will be launching the 5g service in Atlanta, Cleveland, Dallas, Las Vegas, Los Angeles and New York. Customers who are not in these six cities can still purchase the phone and use T-Mobile’s LTE network. T-Mobile at this time is not requiring you to purchase a special data plan to access the new network. T-Mobile will utilize mmWave technology, however it’s very limited. They plan to launch a larger 5G network later this year using the low-band 600Mhz 5G spectrum, a technology not supported by the Galaxy S10 5G.
