T-Mobile US completed its acquisition of most of UScellular’s wireless assets, significantly expanding its network and customer base through the $4.4 billion deal.

The completion of the deal came after the mobile operator agreed in early July to end its diversity, equity and inclusion (DEI) practices, which led to the US Department of Justice’s antitrust division dropping its investigation.

The agreement included T-Mobile acquiring customers, stores and 30 per cent of UScellular’s spectrum.

Former UScellular customers will be allowed to stay on their current mobile phone plans with most of their devices continuing to work on T-Mobile’s network.

Once the networks and systems are integrated, T-Mobile stated those subscribers can migrate to one of its premium plans which include benefits such as free international roaming, device upgrades, and access to Netflix or Apple+.

Lastly, UScellular’s former subscribers now have access to T-Mobile’s fixed wireless access broadband service in their homes.

T-Mobile CEO Mike Sievert stated on last week’s Q2 earnings call adding UScellular’s spectrum will give it a 50 per cent increase in capacity and a larger presence in rural markets.

Former UScellular CEO Laurent Therival stated the completion of the deal “is a win for customers and communities across the United States”.
