T-Mobile US said on Thursday it will make a Capex spend of $11.7 billion to $12 billion towards buying telecom network equipments in 2021.

Leading telecom equipment makers such as Ericsson and Nokia, among others, will benefit from the development. Ericsson and Nokia have long-term 5G network contracts with T-Mobile.

T-Mobile said its Extended Range 5G covers 280 million people across 1.6 million square miles – offering nearly 4x more geographic coverage than Verizon and nearly 2.5x more than AT&T.

T-Mobile’s customers experience download speeds of around 300 Mbps and peak speeds up to 1 Gbps on 5G devices. T-Mobile is upgrading cell sites with high-performance Ultra Capacity 5G to cover both cities and entire metropolitan areas.

The Un-carrier’s Ultra Capacity 5G already reaches 2,400 cities and towns and covers 106 million people, over 50x more than Verizon covers with Ultra Wideband, and is expected to reach 200 million people nationwide by the end of 2021.

Opensignal, based on customer usage from billions of device measurements, says T-Mobile customers now get the fastest 5G download speeds, fastest 5G upload speeds, and a 5G signal more often than anyone else.

Additionally, extensive mobile testing from research firm umlaut (formerly P3) across multiple major markets including Chicago, Houston, New York City and Washington DC also shows T-Mobile leading in 5G speeds.

T-Mobile added more postpaid phone subscribers than rivals AT&T and Verizon Communications in the fourth quarter of 2020, thanks to the latest Apple iPhone launch and benefits from its acquisition of rival Sprint.

The wireless carrier’s postpaid subscriber base rose by 824,000 in the quarter.

T-Mobile expects 2021 postpaid net customer additions to be between 4 million and 4.7 million.

Total revenue of T-Mobile rose to $20.34 billion in the quarter ended Dec. 31, from $11.88 billion a year earlier.
