T-Mobile's story is unusual because the failed AT&T acquisition in 2011 gave the company resources and urgency, while the Sprint merger gave it the mid-band spectrum needed for 5G leadership. The company turned challenger branding into scaled telecom economics. The company is headquartered in Bellevue, Washington.
T-Mobile earns most of its money from recurring monthly wireless service: postpaid phone and multi-line plans, prepaid brands such as Metro by T-Mobile and Mint Mobile, and wholesale access sold to MVNOs. Service revenue was $71.3 billion of its $88.3 billion 2025 total; the rest comes mainly from device sales and installment financing. The same 5G network also carries 5G Home Internet (fixed wireless access), business and government connections, and IoT traffic, while fiber joint ventures with Lumos and Metronet add wired broadband. Spectrum depth lets T-Mobile sell more capacity on towers it has already built, which is why fixed wireless and business lines add revenue without a separate network.
Chief Executive Officer
2025 – Present
1 year (current)
Gopalan managed the incredibly aggressive integration of Sprint's massive network assets in Europe before being promoted to the board of the US subsidiary.
As a key executive representing Deutsche Telekom (T-Mobile's majority owner), he ensures the US operations strictly align with the parent company's massive global strategic goals.
President and Chief Executive Officer
2020 – 2025
5 years
Sievert, Legere's former president and COO, led the Sprint integration, the mid-band 5G rollout, the 2021 launch of 5G Home Internet, the Mint Mobile and UScellular deals, and the fiber joint ventures with Lumos and Metronet.
His tenure turned merger synergies into steadily rising free cash flow and the company's first dividend in 2023. He became Vice Chairman in November 2025.
Former Chief Executive Officer
2012 – 2020
8 years
Legere launched the Un-carrier strategy in 2013, dropping two-year contracts, overage fees and many international roaming charges, completed the MetroPCS combination, and negotiated the Sprint merger announced in 2018.
He took over after the failed AT&T sale and turned T-Mobile into the fastest-growing US carrier of the 2010s.
The US wireless market is mature, promotional competition is intense, and network leadership requires constant spectrum and capital investment. T-Mobile must keep churn low, defend its 5G advantage as Verizon and AT&T improve C-band deployments, grow home internet without overloading the mobile network, and manage data privacy, cybersecurity, and telecom regulation.
Mike Sievert is the President and Chief Executive Officer of T-Mobile US, appointed on April 1, 2020. Sievert previously served as Chief Commercial Officer and Chief Operating Officer, playing an instrumental role alongside John Legere in designing and executing the Un-carrier revolution.
John Legere served as CEO from September 2012 to April 2020. Ditching traditional corporate suits for bright magenta t-shirts and leather jackets, Legere used foul-mouthed authenticity and consumer empathy to attack AT&T and Verizon, leading T-Mobile from a struggling #4 carrier to acquiring Sprint in a $26B merger.
John W. Stanton served as Chairman and CEO of Western Wireless and VoiceStream Wireless from 1994 until its sale to Deutsche Telekom in 2001. A pioneering wireless architect, Stanton built the company's GSM digital network and negotiated the landmark $35 billion transaction.
Robert Dotson served as CEO of T-Mobile USA from 2003 to 2011, overseeing initial nationwide brand expansion. He was succeeded by Philipp Humm (2010–2012), who led the company during the attempted $39 billion takeover by AT&T before departing for Vodafone.
Legere cultivated over 5 million followers on Twitter (now X) and broadcasted a weekly Facebook Live cooking show called "Slow Cooker Sunday." He personally responded to customer complaints, criticized competitor CEOs, and turned executive transparency into a viral marketing weapon.
Sievert earned an economics degree from the Wharton School at the University of Pennsylvania. He built a stellar marketing track record as CMO of AT&T Wireless, Executive VP at E*TRADE, and corporate VP at Microsoft before joining T-Mobile in 2012 as Chief Commercial Officer.
Sievert accomplished one of the smoothest mega-mergers in corporate history: decommissioning 35,000 redundant cell sites more than a year ahead of schedule, migrating millions of Sprint customers without major service outages, and capturing over $7.5B in annual cost synergies.
Sievert shifted T-Mobile from a scrappy value discounter into an undeniable 5G network performance leader. By pairing network superiority with massive share buybacks and 5G Home Internet growth, he propelled TMUS stock past Verizon and AT&T.
Mike Sievert maintains a close strategic partnership with Tim Höttges, CEO of Deutsche Telekom and Chairman of T-Mobile US. Höttges provided critical corporate backing and governance stability that empowered T-Mobile US to execute its aggressive growth initiatives.
Sievert has been named among Barron's Top CEOs and recognized as one of the Most Influential Corporate Executives by Fortune, credited with creating more than $100 billion in shareholder value during his executive tenure.
Sievert's leadership team includes Peter Osvaldik (Chief Financial Officer), Ulf Ewaldsson (President of Technology), Callie Field (President of T-Mobile Business Group), and Jon Freier (President of Consumer Group), fostering operational excellence across network and retail divisions.
Sievert envisions T-Mobile evolving beyond traditional wireless into a universal connectivity powerhouse—dominating fixed wireless broadband, expanding gigabit fiber partnerships, leading in AI customer care, and preparing the infrastructure for early 6G commercial deployment.
