T-Mobile keeps adding phone and home internet subscribers as it continues 5G lead

T-Mobile added 2.9 million phone subscribers in 2021 and forecast its midband 5G network would reach 300 million people by 2023. In three months ending December 31, T-Mobile added 844,000 postpaid customers, a subscriber category prized by carriers for long-term revenue and overall success. It also added 224,000 net customers of its high-speed internet service. The country's third-largest carrier also repeated some achievements it had previously announced; its Ultra Capacity 5G network, made up largely of the 2.5GHz midband spectrum acquired from the Sprint merger, reached 210 million people by the end of 2021, exceeding its goal by 10 million. In a swipe at other carriers, T-Mobile claimed that it will take its competitors years to reach that number. That seems to be supported by the rivals' own estimates, with AT&T expecting to reach 200 million people by the end of 2023. In that time, T-Mobile said it will grow its Ultra Capacity 5G network to reach 260 million people by the end of this year and 300 million people by the end of 2023. This expansion includes more midband service as T-Mobile integrates the small amount of C-band spectrum the carrier bought in 2021 and the portion of 3.45 GHz spectrum acquired in an FCC auction last year. It's unclear how the carrier's Ultra Capacity 5G network will expand with both spectrum tranches, though customers should expect C-band service and 3.45GHz midband integrated in 2023.
