Telecommunications giant T-Mobile has filed a lawsuit against Broadcom seeking continued support for its perpetual VMware licenses. The company, which runs tens of thousands of virtual machines on approximately 303,140 CPU cores using VMware software, stated it is migrating off the platform but highlighted the time-consuming and technical challenges involved in moving over 1,000 applications. The complaint, filed in the Supreme Court of the State of New York in August 2025, was first reported by The Register today.
The legal dispute between T-Mobile and Broadcom over perpetual VMware licenses
According to the complaint, T-Mobile argues that Broadcom was contractually obligated to support VMware perpetual licenses after acquiring the company. Broadcom, however, has shifted licensing policies toward subscriptions, sparking discontent among enterprise customers. T-Mobile is asking the court to rule on the support obligation while proceeding with migration to reduce VMware dependency. This dispute highlights tensions in the IT sector following the $69 billion acquisition.

The technical challenge of migrating from VMware for T-Mobile
The migration process is particularly complex due to the large number of applications and the infrastructure spread across hundreds of thousands of CPU cores. T-Mobile noted that the move requires time and specialized expertise and cannot be completed quickly. Other telecom operators may face similar situations given VMware's prevalence in data centers. T-Mobile's decision to sue could influence strategies for other major clients.
Impact on the telecommunications and cloud industries
This case fits into a broader context of software contract renegotiation and cost optimization. Tech companies are reassessing dependencies on single vendors, as seen in other areas, such as the rising emissions of Google and Amazon linked to AI. If Broadcom loses, it might be forced to maintain legacy support, affecting the perpetual license market. For T-Mobile, migration is a strategic investment, but the lawsuit seeks to ensure a smooth transition without service disruptions.
