T-Mobile today reported its Q2 2020 earnings, which is the first quarter that includes Sprint following the merger of the two carriers. And it looks like combining with Sprint helped T-Mobile to achieve a big feat.

T-Mobile says that it has surpassed AT&T in total branded customer count to become the second biggest carrier in the US, trailing only Verizon. In Q2 2020, T-Mobile added 1.245 million customers, giving it a total subscriber count of 98.3 million.

To compare, AT&T finished Q2 2020 with 93 million postpaid and prepaid customers.

T-Mo also shared some good news regarding its 5G network today. The magenta carrier's 2.5GHz mid-band 5G is now live in Atlanta, Dallas, and Washington DC. That 2.5GHz 5G coverage is also live in parts of Chicago, Houston, Los Angeles, New York City, and Philadelphia.

T-Mobile's 2.5GHz 5G helps to give customers faster speeds in cities where its available. T-Mo touts that its average download speeds on 2.5GHz 5G is around 300Mbps with peak speeds of 1Gbps. You do need a 2.5GHz 5G-enabled phone to access this coverage, and those include the Galaxy S20 series, Galaxy Note 10+ 5G, OnePlus 7T Pro 5G McLaren, OnePlus 8, and LG V60 ThinQ 5G, as well as the upcoming Galaxy Note 20 and Note 20 Ultra.
