T-Mobile has announced that its 5G home internet service is now available in more cities, spanning parts of Colorado, Oklahoma, Missouri, Iowa, and Kansas. The service now covers more than 40 million homes, and earlier this spring, the company said it signed up its one-millionth customer. That’s good news in our landscape of cable internet provider monopolies, but T-Mobile has some real work to do if it plans to meet its goal of 7 to 8 million customers by 2025.
