T-Mobile
T-Mobile is the second-largest wireless carrier in the United States with approximately 125 million customers, operating the nation's largest 5G network following its 2020 merger with Sprint. Once celebrated as the consumer-friendly 'Un-carrier,' T-Mobile has increasingly adopted the practices it once disrupted, raising prices on existing customers, monetizing user data through its advertising platform, and accumulating $92 million in FCC fines for illegally sharing customer location data.

Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
T-Mobile USA operated as the smallest of four national wireless carriers under Deutsche Telekom ownership, competing with AT&T, Verizon, and Sprint. The U.S. wireless industry relied on two-year contracts with early termination fees, device subsidies that masked true costs, and opaque pricing structures that were standard across all carriers. T-Mobile's small market share limited its competitive power but also its extraction capability.
Under new CEO John Legere, T-Mobile launched its Un-carrier strategy, eliminating mandatory two-year contracts, introducing transparent pricing with the Simple Choice plan, and separating device costs from service fees. The company genuinely disrupted the wireless industry, forcing competitors to match consumer-friendly moves. The MetroPCS reverse merger brought T-Mobile to public markets and expanded its subscriber base.
T-Mobile's subscriber growth accelerated but early extraction patterns emerged alongside the consumer-friendly brand. The $90 million FTC cramming settlement revealed T-Mobile had profited from millions of unauthorized third-party charges. The Binge On program throttled all video traffic while marketing it as free streaming. The NLRB ruled multiple employee policies illegal. T-Mobile introduced the 'Un-contract' price guarantee whose fine print contradicted its public promise. Location data sales to aggregators began during this period.
The $26.5 billion Sprint merger reduced the national carrier market from four to three, granting T-Mobile enormous market power. Legere departed, replaced by Sievert. The location data scandal escalated toward what would become a $92 million FCC fine. Massive data breaches in 2021 and 2023 exposed over 100 million customer records. T-Mobile launched its advertising platform to monetize customer data. The Dish Network fourth-carrier remedy was already showing signs of failure.
T-Mobile pivoted from subscriber growth to shareholder extraction, initiating $14 billion in buybacks and its first dividend. The company laid off 5,000 employees despite merger job creation promises. The advertising platform expanded with app-tracking data monetization. The Price Lock guarantee's deceptive fine print became central to customer complaints as price increases loomed. Regulatory fines accumulated from data breaches and location data sales, while T-Mobile lobbied against device unlock requirements.
T-Mobile completed its transformation from Un-carrier disruptor to extraction-focused incumbent. Multiple rounds of price increases broke Un-contract promises, triggering class actions and an NAD deceptive advertising ruling. The company acquired Vistar Media and Blis to build a full advertising stack monetizing customer data. UScellular's acquisition further consolidated the market. Shareholder returns exceeded $31 billion while layoffs continued. The Dish fourth-carrier remedy collapsed entirely, validating merger opponents' concerns.
Alternatives
Prepaid MVNO that runs on T-Mobile's network at $15-30/month for unlimited talk/text with data. Now fully owned by T-Mobile (acquired for $1.35B in 2024), so you're still in T-Mobile's corporate family, but Mint operates as a separate brand with lower prices, no postpaid contract, and no deceptive Price Lock guarantees. Easy switch via eSIM; trade-off is online-only customer service and deprioritized data during congestion.
Unlimited data, talk, and text on Verizon's network for $25-45/month with no annual contract. Good option if you want to leave T-Mobile's network entirely while keeping costs low. eSIM support makes switching straightforward. Owned by Verizon, so you're trading one large carrier for another, but at a significantly lower price.

FBI and DOJ Impose National Security Agreement on Deutsche Telekom Merger
As a condition for FCC approval of the Deutsche Telekom/VoiceStream merger, the FBI and DOJ required a national security agreement signed on January 12, 2001. The agreement mandated all VoiceStream network infrastructure reside in the United States and be accessible for lawful electronic surveillance 24 hours a day. The deal faced scrutiny because the German government still owned 58.2% of Deutsche Telekom, raising foreign ownership concerns under Section 310 of the Communications Act.
Deutsche Telekom Acquires VoiceStream for $35 Billion
Deutsche Telekom AG completed its $35 billion acquisition of VoiceStream Wireless and $24 billion acquisition of Powertel, gaining entry to the U.S. wireless market. The combined entity was renamed T-Mobile USA in 2002, inheriting VoiceStream's GSM network as the smallest of the four national carriers.
FCC Fines T-Mobile $1.25 Million for E911 Compliance Failures
The FCC issued a $1.25 million forfeiture order against T-Mobile USA for failing to comply with Phase I E911 requirements, which mandate that wireless carriers provide location information for emergency 911 calls. An investigation found that of 531 E911 requests at least six months old, T-Mobile had failed to fulfill hundreds without explanation, putting public safety at risk.
Industry-Standard Two-Year Contracts Lock In T-Mobile Customers
Like all major U.S. carriers, T-Mobile required two-year service contracts with early termination fees of up to $200-350 per line for new customers receiving device subsidies. Switching carriers meant paying significant ETFs and losing device subsidies. Nielsen research found that up to 40% of wireless families were deterred from switching carriers due to these financial penalties.
T-Mobile Distributes Anti-Union Memo to Supervisors
T-Mobile distributed an anti-union memorandum to managers and supervisors instructing them on how to suppress Communications Workers of America organizing efforts at call centers. Workers were disciplined for speaking with union organizers, and security guards harassed employees interested in union contact. The CWA documented a pattern of anti-union tactics including surveillance and intimidation across T-Mobile's U.S. operations.
DOJ Blocks AT&T's $39 Billion Acquisition of T-Mobile
The U.S. Department of Justice filed an antitrust lawsuit to block AT&T's $39 billion acquisition of T-Mobile USA, arguing it would reduce the national carrier market from four to three and create a duopoly with Verizon controlling over two-thirds of subscribers. AT&T abandoned the bid in December 2011, preserving T-Mobile as an independent competitor.
T-Mobile Launches Un-carrier 1.0, Eliminates Contracts
New CEO John Legere launched the Un-carrier strategy, eliminating mandatory two-year service contracts and separating device payments from service plans. The Simple Choice plan offered unlimited talk and text with 500MB data for $50/month with no early termination fees, directly challenging industry norms at AT&T, Verizon, and Sprint.
T-Mobile Goes Public via MetroPCS Reverse Merger
T-Mobile USA completed a reverse merger with MetroPCS Communications, creating T-Mobile US, Inc. with a public listing on the NYSE under ticker TMUS. Deutsche Telekom retained approximately 74% ownership. The MetroPCS brand was retained as a prepaid subsidiary, expanding T-Mobile's market reach to budget-conscious consumers.
FTC Settles $90 Million Cramming Case Against T-Mobile
The FTC announced a $90 million settlement with T-Mobile over mobile cramming charges. T-Mobile had placed millions of dollars in unauthorized third-party charges (horoscopes, love tips, celebrity gossip at $9.99/month) on customer bills, retaining 35-40% of each charge. The settlement required full consumer refunds plus $18 million to state attorneys general and $4.5 million to the FCC.
T-Mobile Stops Reporting Wholesale MVNO Customer Numbers
T-Mobile ceased separately reporting customer numbers for its wholesale MVNO segment beginning in Q3 2015, reducing transparency about wholesale business practices. As T-Mobile grew its subscriber base through MetroPCS and direct customers, MVNOs that relied on T-Mobile's network faced increasingly deprioritized traffic during congestion, with no public reporting on wholesale service quality or MVNO customer counts.
T-Mobile Launches Binge On, Throttling All Video Traffic
T-Mobile launched Binge On, offering zero-rated video streaming from 42 partner providers. However, the EFF confirmed it throttled all video traffic to 1.5Mbps regardless of whether the provider was a partner, applying to every user unless they explicitly opted out. YouTube accused T-Mobile of degrading video quality in violation of FCC net neutrality rules.
NLRB Rules 11 T-Mobile Employee Policies Violate Federal Law
A National Labor Relations Board judge ruled that 11 of T-Mobile's employee policies violated federal labor law, including restrictions on workers discussing wages and working conditions with each other and the media. The ruling found T-Mobile distributed manuals instructing supervisors to suppress organizing efforts and disciplined employees for speaking with union organizers.
T-Mobile Announces Un-contract Price Guarantee Promise
T-Mobile launched the 'Un-contract' guarantee for Simple Choice and T-Mobile ONE plans, publicly pledging to never change the price customers pay. CEO Legere stated 'only YOU have the power to change the price you pay.' The actual terms, buried in fine print, only promised to pay the customer's final month if T-Mobile raised prices and the customer left within 60 days.
T-Mobile Shifts to 24-Month Bill Credits for Phone Promotions
T-Mobile expanded its use of 24-month recurring device credits (bill credits) tied to Equipment Installment Plans for 'free' and discounted phone promotions. While marketed as contract-free, customers who left before 24 months forfeited remaining credits and owed the device balance, often $400-800. This effectively recreated two-year financial lock-in that the Un-carrier brand had promised to eliminate.
T-Mobile and Sprint Announce $26 Billion Merger
T-Mobile and Sprint announced a $26 billion all-stock merger to combine the third and fourth largest U.S. wireless carriers. T-Mobile promised lower prices, thousands of new jobs, and the nation's first broad 5G network. Consumer groups, labor unions, and 13 state attorneys general opposed the deal, warning it would eliminate competition and raise prices.
Location Data Sales to Bounty Hunters and Bail Bondsmen Exposed
The New York Times and Senator Ron Wyden revealed that T-Mobile, along with AT&T and Verizon, was selling customer real-time location data to aggregators. The data flowed through companies like Zumigo and Microbilt to bounty hunters, bail bond companies, and a Missouri sheriff. Motherboard later demonstrated the capability by locating a T-Mobile phone for $300 on the black market.
T-Mobile Hires Former FCC Commissioner Clyburn to Lobby for Merger
Eight months after stepping down from the FCC, former Commissioner Mignon Clyburn was hired by T-Mobile to advise on the Sprint merger. T-Mobile also hired a lobbying firm linked to Trump campaign manager Corey Lewandowski and former FCC Commissioner Robert McDowell. Consumer advocates called it a textbook example of the revolving door between regulators and the industries they oversee.
Deutsche Telekom Secures 43% Stake in Combined T-Mobile/Sprint
Sprint and T-Mobile amended their merger agreement to give Deutsche Telekom a higher ownership stake of approximately 43% in the combined company, up from the original 41.7%. SoftBank's stake was reduced to 24%. The restructured deal concentrated control with Deutsche Telekom while creating a $72 billion enterprise valued company, setting the stage for aggressive shareholder extraction once merger integration was complete.
Sprint Merger Closes, Reducing U.S. Market to Three Carriers
T-Mobile completed its $26.5 billion merger with Sprint, reducing the U.S. national wireless carrier market from four to three players. John Legere departed as CEO, replaced by Mike Sievert. The DOJ required T-Mobile to divest Sprint's prepaid business (Boost Mobile) to Dish Network and provide Dish seven years of network access to establish a fourth carrier.
T-Mobile Blocks Locked Devices from Working on MVNOs
T-Mobile began restricting locked phones from being activated on MVNOs that use T-Mobile's network, including Mint Mobile and Simple Mobile. Previously, T-Mobile-locked devices could be used on T-Mobile MVNOs since they still operated on the same network infrastructure. The change first affected Samsung devices, then extended to Google Pixel and other brands, creating an additional switching barrier for customers seeking lower-cost alternatives.
Massive Data Breach Exposes 76 Million Customer Accounts
A hacker named John Binns brute-forced T-Mobile's network through testing environments, exposing personal information of 76 million current, former, and prospective customers. Compromised data included names, dates of birth, Social Security numbers, and driver's license numbers. The hacker publicly called T-Mobile's security 'awful.' T-Mobile offered two years of free identity protection.
T-Mobile Launches Advertising Platform Using Customer Data
T-Mobile rebranded and expanded its advertising business as T-Mobile Advertising Solutions, using network-level data to track customer app usage, web browsing, and behavior patterns. The platform bundles this data into targetable 'personas' for advertisers. Opt-out is buried in privacy settings and does not cover all data collection. Only Android users are tracked; iOS is excluded due to Apple's privacy protections.
T-Mobile Launches $14 Billion Stock Buyback Program
T-Mobile initiated a $14 billion share repurchase program running through September 2023, marking the beginning of its aggressive shareholder return strategy. By October 2023, the company had repurchased 104.3 million cumulative shares for $14.7 billion, prioritizing capital returns to shareholders over reinvestment in network quality or customer pricing improvements.
Second Major Data Breach Compromises 37 Million Accounts
T-Mobile disclosed that a threat actor had accessed an API to steal personal data of approximately 37 million customer accounts, the second major breach in 18 months. In 2022, hackers had breached T-Mobile's network more than 100 times. The repeated breaches demonstrated persistent security failures despite prior commitments to improvement.
T-Mobile Eliminates Credit Card Autopay Discount
T-Mobile reduced the autopay discount for customers paying by credit card from $10 to $5 per line, effectively penalizing customers who preferred credit card payments. The full discount required enrollment in both autopay and paperless billing using a debit card or bank account, adding $5-10 per line for customers who did not comply with the preferred payment method.
T-Mobile Lays Off 5,000 Employees Despite Merger Job Promises
T-Mobile announced the elimination of 5,000 corporate and back-office positions, approximately 7% of its workforce. This came three years after the company promised the Sprint merger would be 'jobs positive,' adding 11,000 positions by 2024. Investigation found T-Mobile already employed 9,000 fewer people than the pre-merger combined headcount before these additional cuts. The company took a $450 million pre-tax charge.
T-Mobile Declares First-Ever Dividend, Expands Shareholder Returns to $19 Billion
T-Mobile announced its first dividend program, paying approximately $3.75 billion in dividends through 2024 as part of a $19 billion second tranche of shareholder returns. Combined with the preceding $14 billion buyback, T-Mobile committed over $33 billion to shareholder returns within two years, concurrent with layoffs and price increases for existing customers.
FCC Fines T-Mobile $80 Million for Illegal Location Data Sales
The FCC announced an $80 million fine against T-Mobile (later increased to $92 million including Sprint) for illegally sharing customer real-time location data with aggregators who resold it to bounty hunters, bail bond companies, and unauthorized third parties. The investigation traced back to 2018 revelations. T-Mobile appealed but a court upheld the fine.
T-Mobile Raises Prices on Legacy Plans, Breaking Un-contract Promise
T-Mobile imposed $2-5 per line per month increases on Simple Choice, Magenta, T-Mobile ONE, and other legacy plans, including plans sold with the 'Un-contract' guarantee that prices would never change. Over 2,000 customers filed complaints with the FCC. Multiple class action lawsuits were filed alleging deceptive practices and breach of the price guarantee.
T-Mobile Announces $4.4 Billion UScellular Acquisition
T-Mobile agreed to acquire substantially all of UScellular's wireless operations for approximately $4.4 billion, including more than 4 million customers in 21 states. The deal further concentrated the wireless market, prompting U.S. senators to urge DOJ and FCC scrutiny. The acquisition closed in August 2025 after FCC approval.
NAD Rules T-Mobile Price Lock Advertising Deceptive
The National Advertising Division ruled that T-Mobile's 'Price Lock' guarantee was deceptive and recommended the claim be discontinued. The ruling, stemming from an AT&T complaint, found that 'Price Lock' does not actually lock prices but merely offers to pay one final month's bill if a customer leaves due to a price increase. T-Mobile's terms had been available only in online fine print, not presented at sign-up.
T-Mobile Ends Early Payoff of Promotional Devices
T-Mobile changed its bill credits policy so that customers on promotional device installment plans who pay off their phones early forfeit remaining monthly credits. Previously, customers could pay off devices early and keep receiving credits. The policy effectively locked customers into 24-month payment cycles, with customers calling it a covert return to two-year contracts.
CFIUS Fines T-Mobile Record $60 Million for National Security Violations
The Committee on Foreign Investment in the United States assessed a $60 million penalty against T-Mobile, the largest CFIUS fine ever disclosed, for unauthorized data access incidents following the Sprint merger. T-Mobile breached its national security agreement by failing to protect sensitive data and failing to promptly report incidents between August 2020 and June 2021.
T-Mobile Opposes FCC 60-Day Device Unlock Rule Using Chevron Ruling
T-Mobile filed formal opposition to the FCC's proposed rule requiring carriers to unlock all phones within 60 days of purchase. T-Mobile invoked the Supreme Court's recent Chevron ruling to argue the FCC lacks statutory authority to impose the mandate, calling it a 'major question' requiring Congressional authorization. The filing directly contradicted T-Mobile's original Un-carrier identity of reducing switching barriers.
T-Mobile Settles FCC Data Breach Investigations for $31.5 Million
T-Mobile agreed to pay $31.5 million to settle FCC investigations into data breaches in 2021, 2022, and 2023 that compromised millions of customer accounts. Half went to a civil penalty and half to mandatory cybersecurity investments including zero-trust architecture, phishing-resistant multifactor authentication, and a chief information security officer with board-level reporting.
T-Mobile Updates Activation Policy, Restricting MVNO Use
T-Mobile updated its activation policies to create additional barriers for customers attempting to use T-Mobile-purchased phones on MVNO networks. The policy change restricted device portability to lower-cost alternatives that depend on T-Mobile's network, further tightening switching costs and MVNO competitive dynamics.
Class Action Filed Over Deceptive RPTR Fee Disguised as Government Charge
A class action lawsuit was filed alleging T-Mobile's 'Regulatory Programs and Telco Recovery' fee of $3.49 per voice line, introduced in 2004 and increased multiple times, is deceptively disguised as a government-mandated charge. The fee is grouped with legitimate government taxes on customer bills despite being entirely set by T-Mobile. Plaintiffs alleged violations of federal Truth-in-Billing rules and state consumer protection laws.
T-Mobile Acquires Vistar Media for $600 Million to Expand Ad Business
T-Mobile announced its acquisition of Vistar Media, a leading digital out-of-home (DOOH) advertising platform, for $600 million. The deal gave T-Mobile access to a global network of over 1.1 million digital screens and 3,000 brand advertisers. Combined with its existing customer data monetization platform, the acquisition positioned T-Mobile as a major advertising technology player.
T-Mobile Acquires Blis for $175 Million, Further Expanding Ad Tech
T-Mobile announced the $175 million acquisition of Blis, an omnichannel advertising platform, just weeks after completing the Vistar Media deal. Blis provides cookie-less targeting and cross-device tracking capabilities. The combined acquisitions created an end-to-end advertising stack combining T-Mobile's first-party customer data with programmatic ad buying across digital screens, mobile, and out-of-home channels.
T-Mobile Completes UScellular Acquisition, Adding 4 Million Customers
T-Mobile closed its $4.3 billion acquisition of UScellular's wireless operations, adding approximately 4.5 million subscribers in 21 states. The deal further consolidated the U.S. wireless market, particularly in rural areas where UScellular had been the primary competitor. T-Mobile projected $1.2 billion in annual cost synergies, accelerating integration to roughly two years.
Dish Network Sells Spectrum to AT&T, Merger Competition Remedy Fails
EchoStar (Dish's parent) announced a $23 billion sale of its 3.45 GHz and 600 MHz spectrum to AT&T and the transition of Boost Mobile to an MVNO model, effectively ending Dish's attempt to build a fourth national wireless carrier. The collapse validated merger opponents' warnings that the DOJ's competition remedy was unrealistic. By the end of 2025, the U.S. was back to three national carriers.
T-Mobile Lays Off 393 Workers in Washington Including VP Roles
T-Mobile cut 393 employees across Washington state, including seven vice president and senior vice president positions and over 200 senior and director-level employees. The layoffs came alongside $14.4 billion in 2024 shareholder returns, CEO compensation of $37 million, and were followed by additional layoffs of 78 workers in New Jersey. New CEO Srini Gopalan had replaced Sievert in November 2025.
