T-Mobile Challenges Broadcom in Legal Dispute Over VMware Support

T-Mobile has initiated legal action against Broadcom, seeking a court ruling to compel the software giant to continue supporting perpetual VMware licenses. The telecommunications provider alleges that Broadcom’s shift to a subscription-only model violates existing contractual obligations for customers who purchased perpetual licenses prior to the acquisition.

The Conflict Over Perpetual Licenses

The dispute centers on VMware licenses that T-Mobile acquired in 2023. According to a legal filing submitted to the Supreme Court of the State of New York, T-Mobile purchased perpetual licenses along with a two-year support agreement, which included an option to purchase a third year of coverage.

Following Broadcom’s acquisition of VMware, the company discontinued the sale of perpetual licenses, transitioning its business model toward subscription-based services. Broadcom also began bundling products into more expensive packages. When T-Mobile attempted to exercise its option to extend support for a third year—a transaction valued at $5,288,398.45—Broadcom declined the request.

A Broadcom representative stated via email, as cited in the T-Mobile filing, that the company had “announced end of available of all perpetual products, which includes Stated Out Year Renewals for perpetual support.”

Operational Challenges for T-Mobile

T-Mobile currently maintains a massive infrastructure footprint, relying on tens of thousands of virtual machines across approximately 303,140 CPU cores. The company is in the process of migrating its systems away from VMware, but it faces significant technical hurdles.

In its complaint, T-Mobile noted that the migration process involves over 1,000 applications. The company argues that the sudden cessation of support services creates an unacceptable risk to its operations while this transition is underway.

Court Intervention and Current Status

The legal battle reached an interim resolution in late 2025. A judge granted T-Mobile an injunction, allowing the company to receive support services from October 2025 through August 3, 2026. This temporary measure requires T-Mobile to pay $5.28 million for the continued support and post a $500,000 undertaking.

T-Mobile is now seeking a permanent declaration from the court that it was contractually entitled to renew its support services beyond the current injunction period. The case highlights the friction between legacy enterprise software customers and the aggressive licensing changes implemented by Broadcom following its acquisition of VMware.

Key Takeaways

• Legal Filing: T-Mobile filed suit in the Supreme Court of the State of New York in August 2025.
• The Core Dispute: Broadcom refused to honor a third-year support renewal for perpetual licenses purchased by T-Mobile in 2023.
• Operational Scope: T-Mobile’s environment spans hundreds of thousands of CPU cores and more than 1,000 applications, complicating the move to alternative platforms.
• Court Ruling: A judge granted a temporary injunction, ensuring support for T-Mobile through August 3, 2026, while the broader case proceeds.

This case reflects broader industry concerns regarding the transition of enterprise software from perpetual models to recurring subscription fees. As organizations like T-Mobile navigate these shifts, the legal outcomes of such disputes may set precedents for how software vendors manage end-of-life cycles for legacy products.
