T-Mobile will gain US Cellular’s customers, stores, and spectrum, while US Cellular will keep its towers and focus on leasing them out. Critics worry the merger could reduce competition, especially in rural areas, but US Cellular customers shouldn’t see immediate changes at least. Last year, T-Mobile announced plan
