T-Mobile customers, employees and job applicants were the subject of several class actions in 2026, and in September a federal judge sent the Price Lock rate-hike claims to individual arbitration. None of the pending T-Mobile lawsuits has a settlement or claim form as of October 21, 2026.
Allegations Only · No Open Claims
This article summarizes class action complaints and court rulings. The claims in the pending lawsuits are unproven allegations. T-Mobile has not been found liable in any of them, no class has been certified in any of them, and there is nothing to claim from them at this time. This page is informational and is not legal advice.
What Is This About?
T-Mobile faces class actions from several directions in 2026: customers challenging price increases and promotions, a website visitor challenging online tracking, employees challenging the company’s 401(k) plan, and AT&T and Verizon customers challenging the 2020 Sprint merger. Two employment settlements also moved forward this year.The biggest development came in late September 2026, when a federal judge in Seattle ruled that customers suing over T-Mobile’s Price Lock rate increases must take their claims to individual arbitration. That ruling shows how T-Mobile’s customer agreement, which contains an arbitration clause, shapes which customer claims can proceed as class actions at all.

Price Lock Rate-Hike Claims Sent to Arbitration
The Price Lock case began in July 2024, when T-Mobile customers sued in federal court in New Jersey over 2024 price increases on older plans. They pointed to a January 2017 T-Mobile announcement that said the company would “never change the price you pay for your T-Mobile ONE plan,” and alleged the company misrepresented that their prices would not rise for life. According to reporting on the complaint, one plaintiff’s bill rose $5 per line, and another’s Magenta military plan went from $100 to $120 a month.The case is now pending in federal court in Seattle as Oddo v. T-Mobile USA, Inc., No. 2:25-cv-01651, before U.S. District Judge Richard A. Jones. In late September 2026 the judge ruled that the customers must arbitrate their claims individually, agreeing with T-Mobile that they accepted its arbitration agreement by continuing to use and pay for service after notice of updated terms, according to Law360. The court stayed the case, and on October 13, 2026 the plaintiffs filed a motion asking the judge to reconsider.
Unless that ruling changes, there will be no class settlement or class judgment over the Price Lock increases in this case.
A 401(k) Suit Over T-Mobile’s Retirement Plan
On July 31, 2026, a T-Mobile retirement plan participant filed Miner v. T-Mobile USA, Inc., No. 2:26-cv-02724, in federal court in Seattle against T-Mobile, its board and its retirement plans committee. The complaint alleges the defendants breached their duties under the Employee Retirement Income Security Act by keeping the T. Rowe Price Growth Stock Trust in the T-Mobile 401(k) plan, a fund it says has been in the plan since at least 2009 and trailed its benchmark, the Russell 1000 Growth Index, by 346 percentage points cumulatively over that time.The complaint proposes a class of plan participants and beneficiaries who invested in the fund from January 1, 2021 through judgment, and alleges the underperformance cost the plan hundreds of millions of dollars. Sanford Heisler Sharp McKnight, LLP filed the complaint. A second ERISA suit against T-Mobile and its retirement plans committee, Haines v. T-Mobile USA, Inc., No. 2:26-cv-02946, was filed in the same court on August 19, 2026 and marked as related to Miner. The allegations in both cases are unproven.
The $200 Gift Card Lawsuit
Ghrabeti v. T-Mobile USA, Inc., filed in November 2025 by a California customer, alleges T-Mobile advertised, or let store staff advertise, $200-per-line gift card promotions it did not honor. According to Newsweek’s account of the complaint, the plaintiff bought two lines in June 2024 after being promised $400 in gift cards, and a supervisor said in September 2024 that the promotion did not exist. The suit brings California false advertising and unfair competition claims on behalf of California customers, and Newsweek reported in March 2026 that it was at an early stage with no response from T-Mobile.The Website Tracking Lawsuit
In May 2026, a California resident sued T-Mobile in Los Angeles County Superior Court alleging its website let third-party cookies from companies including Amazon, Facebook and Twitter collect visitors’ browsing data even after visitors rejected third-party cookies, Courthouse News reported. The suit relies on California’s trap and trace law, part of the California Invasion of Privacy Act, and says the amount in controversy exceeds $3 million. T-Mobile did not immediately respond to the report.The Sprint Merger Antitrust Case
Dale v. Deutsche Telekom AG, No. 1:22-cv-03189, filed in 2022 in federal court in Chicago, is brought on behalf of AT&T and Verizon customers, not T-Mobile customers. It alleges the 2020 T-Mobile and Sprint merger reduced competition and that AT&T and Verizon customers paid artificially inflated prices as a result. The court denied T-Mobile’s motion to dismiss in November 2023, and T-Mobile’s 2026 quarterly reports describe the case as pending and say the company is defending it.Recent T-Mobile Settlements
The T-Mobile Washington job postings settlement resolves claims that T-Mobile posted Washington job openings without the pay ranges state law requires. It has a maximum fund of $2,137,500, claims closed September 8, 2026, and Judge David Whedbee of King County Superior Court is set to hold the final approval hearing on October 23, 2026. T-Mobile denies the claims.The $3.65 million T-Mobile SMB account executive settlement over alleged unpaid overtime paid out in February 2026, and the roughly $350 million settlement over T-Mobile’s 2021 data breach is long past its claim deadline. Neither accepts new claims.
Elsewhere in the T-Mobile family, Law360 reported on June 18, 2026 that Mint Mobile, which T-Mobile owns, faces a proposed class action alleging it advertised home internet discounts that did not exist.
Questions
Is there a T-Mobile class action settlement open for claims?
Not as of October 21, 2026. The most recent T-Mobile settlement with a claim form, the Washington job postings settlement in Lowe v. T-Mobile USA, Inc., closed to claims on September 8, 2026, and its final approval hearing is set for October 23, 2026. The pending lawsuits described on this page have no settlement or claim form.
What happened to the T-Mobile Price Lock lawsuit?
In late September 2026, the federal judge overseeing Oddo v. T-Mobile USA, Inc. in Seattle ruled that the customers must arbitrate their claims individually rather than as a class, according to Law360. The judge agreed with T-Mobile that customers accepted an arbitration agreement by continuing to use and pay for service after notice of updated terms. The plaintiffs asked the judge to reconsider on October 13, 2026.
What is the T-Mobile 401(k) lawsuit about?
Miner v. T-Mobile USA, Inc., filed July 31, 2026 in federal court in Seattle, alleges the company and its retirement plan committee breached their duties under ERISA by keeping the T. Rowe Price Growth Stock Trust in the T-Mobile 401(k) plan despite years of underperformance against its benchmark. It proposes a class of plan participants who invested in that fund from January 1, 2021. The allegations are unproven.
Is the 2021 T-Mobile data breach settlement still paying?
The claim deadline for the roughly $350 million settlement over T-Mobile’s 2021 data breach passed in 2023, and the settlement is no longer accepting claims. It is separate from every lawsuit listed on this page.
