4 Phone Carriers You May Not Realize Are Owned by T-Mobile

The telecommunications industry has gone through many phases of change in the United States: growth, monopoly, mandatory breakup, reconsolidation, then a new era of Wild West expansion, before repeating the cycle. During this time, prices for cell phone services have changed as much as the phones themselves. We also went from having a wide range of service providers to three: AT&T, Verizon, and T-Mobile.

Each of the companies has used mergers and acquisitions to grow its business, but T-Mobile’s recent record has been the most dramatic. In 2020, the operator partnered with the fourth largest US mobile network, Sprint. In 2024, T-Mobile regained US Cellular’s customer base. Two years later, the second largest network of 2026 claims more than 140 million subscribers. But there’s more to T-Mobile than just T-Mobile itself. The company also owns several smaller carrier brands, operating under different business models and offering different service packages. Some are more obvious than others, but you might be surprised to learn exactly which brands fall under the company’s magenta umbrella.

MetroPCS launched in 1994 as one of several new wireless carriers and grew into a decent mid-sized player over the next decade. MetroPCS was the first in the United States to launch 4G LTE in September 2010, beating Verizon by three months.

The industry’s race toward national 4G networks has sparked a rush of takeover offers. For MetroPCS, it was T-Mobile’s proposed merger that won out over Sprint and Dish Networks in 2012. The deal closed the following year. MetroPCS has retained its prepaid service model and still operates and franchises retail locations separate from its parent company. The name stuck until 2018, when it was remixed to Metro by T-Mobile. Nowadays, it faces tough competition for offering one of the best $50 unlimited mobile plans on the market.

You may know Mint Mobile as that network with “Deadpool” star Ryan Reynolds in its commercials. Hell, you might even remember that he was a part owner at one point. The carrier, known as a mobile virtual network operator, or MVNO, officially launched in 2016 under a sort of wholesale model: Customers can get monthly service on T-Mobile’s network with unlimited talk and text as well as a monthly bundle of cellular data on terms of three, six or 12 months for a one-time cost that would be less than the equivalent on a postpaid monthly plan. Although it introduced an unlimited plan in 2020, Mint has stood out by offering customers upgrades to their new or existing data plans. Mint has done this several times over the years without raising prices.

T-Mobile broke into Mint Mobile’s holding company, Ka’ena Corporation, in 2023, giving the mobile giant ownership of a unique prepaid service model that was already running on its network. Reynolds’ estimated 25% stake in Mint was bought out, but he remained the carrier’s spokesperson. Mint has since added 5G home internet to its offerings under the same long-term prepaid model.

Ultra Mobile is another MVNO acquired by T-Mobile as part of the Ka’ena Corporation deal in 2024. The company was founded in 2011 by serial telecommunications entrepreneur David Glickman, who ran Justice Technology, which leased access to international satellites and cables and resold it to domestic carriers. In a sense, Ultra Mobile was a knockoff of Justice, targeting expats living in the United States with low-cost, customizable plans that included crucial international coverage. It turns out that Ultra was actually the one who started Mint before splitting it up in 2019 – although the two are ultimately still connected through Ka’ena.

In recent times, Ultra Mobile has integrated Mint’s long-term service plan model into its own offerings, allowing subscribers to opt for a monthly plan or pre-pay for up to a year of service at a lower overall rate. Unlimited calls to more than 90 destinations as well as SMS worldwide remain the keystones of the brand. That said, it focuses on people staying in the United States. If you’re traveling outside of the United States, you’ll need to choose the right international roaming plan for your next trip.

Assurance Wireless began as a Virgin Mobile brand in 2009. At the time, Virgin Mobile in the United States operated as an MVNO on Sprint’s network until it was purchased by T-Mobile in 2020. Assurance participates in the federal government’s USAC Lifeline program, which provides low-income and other vulnerable populations with free phones and services through partner providers. Applicants are accepted into the program based on federal or state criteria. These providers are able to generate revenue beyond the Lifeline grant they receive by offering add-on packages.

Assurance’s presence is a reminder that most of T-Mobile’s customer base is unwilling or unable to spend big money on expensive plans because less than a quarter of its subscribers have postpaid service, especially in an economy where consumers seemingly just can’t keep up.
