NEW YORK — T-Mobile filed a lawsuit against Broadcom in the Supreme Court of the State of New York in August 2025. The lawsuit seeks a ruling that Broadcom is contractually obligated to continue supporting T-Mobile's VMware perpetual licenses.

T-Mobile purchased perpetual VMware licenses with two years of support in 2023, which included an option to buy a third year of support. T-Mobile attempted to extend support for a third year for $5,288,398.45, but Broadcom refused the extension. A Broadcom representative informed T-Mobile via email that "Broadcom announced end of available of all perpetual products, which includes Stated Out Year Renewals for perpetual support."

A judge granted T-Mobile an injunction, allowing it to receive support services from October 2025 through August 3, 2026, for $5.28 million. This injunction also required a $500,000 undertaking. In its complaint, T-Mobile stated it has tens of thousands of virtual machines using VMware software across approximately 303,140 CPU cores.

Broadcom claimed it incurred $24 million in costs to provide T-Mobile with support for six VMware products and to assign three dedicated support account managers. T-Mobile responded that it does not use three of the six products named by Broadcom and has opened only two service cases during the current year. T-Mobile also offered $20 million for two years of software updates and support services.

During an October 2025 hearing, a Broadcom lawyer stated that "Thousands upon thousands have successfully migrated to subscription." The lawyer added, "Thousands upon thousands of customers have already transferred under these sorts of provisions and accepted and understood that end of availability applies." Broadcom previously argued that T-Mobile's case stands out because T-Mobile waited a long time before trying to extend support. T-Mobile indicated it is in the process of migrating off VMware and noted challenges in migrating over 1,000 applications.
