AT&T escalated its battle against T-Mobile’s new customer-switching feature on November 30, 2025, by filing an emergency motion in the U.S. District Court for the Northern District of Texas seeking a temporary and preliminary injunctions to immediately block the tool nationwide.
The Dallas-based carrier accused T-Mobile of deploying artificial-intelligence-powered bots inside its T-Life app that impersonate legitimate customers to extract more than 100 categories of protected account data from password-protected sections of AT&T’s online portals. According to the 47-page complaint and accompanying brief, the Easy Switch feature automatically logs into a user’s AT&T account after the customer enters their credentials inside the T-Life app, then systematically harvests detailed billing, plan, device payment, discount, and usage information without AT&T’s authorization according to a report from Phone Arena.
AT&T told the court that its security teams first detected the unauthorized mass access attempts in mid-November during the tool’s limited beta rollout at the Formula 1 Las Vegas Grand Prix. Engineers quickly deployed blocks, only to discover the next day that T-Mobile had modified the bot to bypass the new defenses. The complaint details at least three additional rounds of blocking and rapid circumvention before the public launch.
The day Easy Switch officially debuted for all T-Mobile customers, the company had disabled the automated login-and-scrape function specifically for AT&T accounts. Users attempting to switch from AT&T are now prompted to manually enter data or upload a PDF bill. However, AT&T maintains that T-Mobile’s public statements and internal code references show intent to restore the automated harvesting once legal pressure eases, and that the tool continues to scrape Verizon customer accounts without restriction.
The filing invokes the Computer Fraud and Abuse Act, the Texas Harmful Access by Computer Act, trespass to chattels, and unjust enrichment claims, arguing that each unauthorized access causes irreparable harm to customer privacy and AT&T’s server infrastructure. It also notified Apple that the T-Life app may violate App Store guidelines prohibiting apps from using automated scripts to retrieve data from third-party services.
T-Mobile responded swiftly in court papers, insisting no emergency exists because the contested AT&T functionality has already been removed. The carrier framed Easy Switch as a consumer-empowerment feature that merely allows individuals to retrieve and share their own information after explicitly granting permission and accepting clear terms of service. It accused AT&T of attempting to lock customers into its ecosystem by misusing anti-hacking statutes to prevent people from voluntarily porting their own data to a competitor.
U.S. District Judge Reed O’Connor granted T-Mobile’s request for additional briefing time, setting a December 8 deadline for its full opposition and scheduling an in-person evidentiary hearing for December 16 in Dallas.
The dispute marks the first major U.S. legal challenge to directly confront the boundaries of AI-assisted account portability tools in the telecom sector. Industry observers note that similar automated switching assistants have operated in European markets under the continent’s stronger data-portability regulations without triggering litigation, highlighting a sharper regulatory divide across the Atlantic.
Verizon, while publicly criticizing the 15-minute switching promise as potentially sacrificing accuracy for speed, has not joined AT&T’s legal action and continues to require traditional manual or agent-assisted number transfers.
As the case moves toward the mid-December hearing, millions of consumers on both sides of the dispute remain able to initiate switches through older manual processes, though the outcome could reshape how aggressively U.S. carriers may use automation to compete for one another’s customers in the future.
