AT&T vs. T-Mobile Lawsuit Over Easy Switch Data Scraping

The AT&T vs. T-Mobile Easy Switch lawsuit is a federal case AT&T filed in November 2025 accusing T-Mobile of using automated bots to break into password-protected AT&T accounts and scrape customer data through its new “Easy Switch” tool. A federal judge in Dallas has already blocked the original version of the tool, AT&T has since expanded the case to include false advertising claims, and a jury trial is scheduled for July 2027.

What AT&T Says T-Mobile Did

T-Mobile launched Easy Switch, also marketed as “Switching Made Easy,” on November 20, 2025, at the Formula 1 Las Vegas Grand Prix.1Fierce Network. T-Mobile Rebuffs AT&T Claims About Easy Switch Built into the T-Life app, the AI-powered feature asked AT&T and Verizon customers to enter their login credentials. An automated system would then sign in to the customer’s account, pull plan details and billing information, and produce a side-by-side comparison with T-Mobile plans. T-Mobile said a customer could complete a switch in as little as 15 minutes.2Phone Arena. AT&T Sues T-Mobile Over T-Life 15-Minute Switching

AT&T filed suit six days later, on November 26, 2025, in the U.S. District Court for the Northern District of Texas, Dallas Division (case number 3:25-cv-03279).3CourtListener. AT&T Services Inc v. T-Mobile US Inc The complaint alleges that T-Mobile’s bots posed as AT&T customers to access secure AT&T systems and harvested more than 100 categories of personal account information, including billing history, physical addresses, installment plans, and usage details.4Fierce Network.

A central allegation is that when AT&T deployed technical measures to block the scraping, T-Mobile reengineered the tool overnight to get around them. AT&T says this happened at least three times between November 24 and November 26, 2025, after AT&T sent a cease-and-desist letter that T-Mobile declined to honor.6RCR Wireless.

The Legal Claims

The complaint raises seven causes of action:

  • Violation of the federal Computer Fraud and Abuse Act (CFAA), for accessing AT&T’s protected computers without authorization.
  • Violation of Texas computer crime statutes, for accessing AT&T servers without effective consent.
  • Violation of California’s Comprehensive Computer Data Access and Fraud Act.
  • Violation of the Georgia Computer Systems Protection Act.
  • Breach of contract, for violating AT&T’s Terms of Use, which prohibit bots and commercial exploitation of site content.
  • Tortious interference with AT&T’s contractual relationships with its customers.
  • Misappropriation.

AT&T asked for both an injunction and damages, claiming more than $5,000 in investigation and remediation costs.8TMO Report. AT&T v. T-Mobile Complaint

How T-Mobile Is Defending the Case

T-Mobile has denied accessing AT&T’s servers directly. Its position is that the customer, not T-Mobile, was accessing the account, and that the customer voluntarily shared their own information after agreeing to the tool’s terms.7Light Reading.

T-Mobile also argued that AT&T’s request for emergency relief was moot because it had already disabled the original version of the tool on November 26, 2025, the same day the complaint was filed. It noted that during the six days the original tool was live, only 342 consumers used it, against a subscriber base of 119 million.

The Court Order Blocking Easy Switch

Judge Karen Gren Scholer granted AT&T a temporary restraining order on December 18, 2025.10Mobile World Live. Judge Sides With AT&T in Lawsuit Against T-Mobile US The order bars T-Mobile and its agents from running the original Easy Switch feature or “any substantially similar version” that accesses or obtains data from AT&T’s protected computer systems without court permission.11Eric Goldman’s Blog.

The judge found AT&T was likely to succeed on the merits, citing unauthorized automated access to password-protected pages, the scraping of more than 100 data fields per user, and irreparable harm to AT&T’s control over its systems and customer privacy. She also pointed to likely violations of the CFAA, the Texas Harmful Access by Computer Act, California’s Comprehensive Computer Data Access and Fraud Act, and the Georgia Computer Systems Protection Act.10Mobile World Live. Judge Sides With AT&T in Lawsuit Against T-Mobile US Although T-Mobile had already modified the tool, the court found the threat was not eliminated because T-Mobile had signaled interest in deploying a “very similar” system in the future.11Eric Goldman’s Blog.

The parties then filed a joint stipulation converting the TRO into a preliminary injunction, which Judge Scholer entered on December 29, 2025.3CourtListener. AT&T Services Inc v.

The Added False Advertising Claims

In mid-February 2026, AT&T filed an amended complaint that broadened the case beyond data scraping. It added false advertising claims aimed at two of the biggest promises in T-Mobile’s “Switching Made Easy” campaign.12Fierce Network. AT&T Raises New Allegations in Switching Spat With T-Mobile

The first target is T-Mobile’s claim that customers can “save over $1,000 per year” by switching. AT&T alleges those savings numbers rest on misleading comparisons, matching a higher-tier AT&T plan against a lower-tier T-Mobile plan, or comparing T-Mobile’s promotional rate against T-Mobile’s own standard rate rather than what the customer actually pays.13Android Headlines.

The second is the “just 15 minutes” claim. AT&T argues that while browsing plans may take that long, porting a number and getting service running on a new network takes hours or days. The complaint singles out T-Mobile television spots featuring Billy Bob Thornton and Druski as examples of the allegedly deceptive messaging.12Fierce Network.

Verizon’s Separate Lawsuit

Verizon filed its own suit against T-Mobile on February 4, 2026, in federal court in Manhattan, targeting the same “Save Over $1,000” advertising. Verizon called the savings claims “mathematical fiction,” alleging T-Mobile compared its promotional rates to Verizon’s standard rates, ignored Verizon’s active promotions, and inflated the value of optional benefits.14RCR Wireless.

Verizon has separately voiced “significant customer privacy concerns” about the Easy Switch scraping, but as of early 2026 had not filed a distinct legal challenge on those grounds. It is not clear whether T-Mobile disabled the automated scraping for Verizon customers the way it did for AT&T customers.16Light Reading. T-Mobile Disables Automated Switching App for AT&T Customers
