T-Mobile is asking a Latest York court to rule that Broadcom was contractually obligated to proceed supporting its VMware perpetual licenses.
In its criticism, T-Mobile said it has tens of 1000’s of virtual machines using VMware software across roughly 303,140 CPU cores. It also said that it was migrating off VMware but noted the time-consuming and technical challenges involved in migrating over 1,000 applications.
It filed its lawsuit, which was first reported by The Register today, within the Supreme Court of the State of Latest York in August 2025 (PDF).
The mobile company claimed that in 2023, it bought perpetual VMware licenses, plus two years of support with the choice to purchase a 3rd 12 months. But after Broadcom bought VMware, it stopped sales of VMware perpetual licenses in favor of subscriptions and commenced bundling VMware products into a couple of, dearer bundles.
When T-Mobile tried to increase support for a 3rd 12 months for $5,288,398.45, Broadcom wouldn’t allow it, per an August 2025 filing from T-Mobile. A Broadcom representative reportedly told T-Mobile via email: “Broadcom announced end of accessible of all perpetual products, which incorporates Stated Out 12 months Renewals for perpetual support.”
A judge granted T-Mobile an injunction that allowed it to receive support services from October 2025 through August 3, 2026, for $5.28 million, plus the posting of a $500,000 undertaking.
Now, T-Mobile seeks a declaration that it was entitled to renew support services and further relief because the court deems crucial.
