Although the news has not gone on the record, T-Mobile has quietly confirmed to Light Reading that it had launched 5G services in 30 cities in the U.S. But it has not yet begun active or commercial services on this network, as compatible 5G smartphones are yet to hit the market.
T-Mobile did not provide details on its 5G deployment progress in those 30 cities. Therefore, it's difficult to assess whether those efforts involve just one or two cell sites or sites that span a full city.
T-Mobile’s launch timeline is relatively close with that of its rivals, like AT&T (T) and Verizon (VZ), with the former already having launched mobile 5G service in 12 cities. Further, it has promised to offer mobile 5G smartphones in the coming months. Sprint and Verizon too have promised mobile 5G launches with smartphones in the coming months.
T-Mobile's 5G plans are noteworthy because the operator is the only major wireless network provider that is planning to launch 5G services on 600MHz spectrum.
