WASHINGTON, March 11, 2026 – The longstanding legal battle between AT&T and T-Mobile continues.

Last month, AT&T filed a revised complaint against T-Mobile, alleging false and deceptive advertising tied to T-Mobile’s “Switching Made Easy” campaign. AT&T also requested injunctive relief, citing monetary damages from customer competition.

The lawsuit, filed in the U.S. District Court for the Northern District of Texas, alleged that T-Mobile used inconsistent savings claims with “apples-to-oranges comparisons” between premium and basic plans, while also displaying “misleading” information on time taken to switch carriers.
