T-Mobile VMware Suit Names 303,140 CPU Cores In Licence Dispute

T-Mobile Names 303,140 CPU Cores In VMware Case

T-Mobile said in its filing that it is asking a New York court to rule that Broadcom must continue supporting VMware perpetual licences while the carrier works through a large migration away from the software.

T-Mobile said the complaint puts the remaining VMware footprint at tens of thousands of VMs and about 303,140 CPU cores.

T-Mobile also said it is migrating off VMware, but cited the technical work involved in moving more than 1,000 applications.

T-Mobile filed the lawsuit in the Supreme Court of the State of New York in August 2025.

The company said it bought VMware perpetual licences in 2023, plus two years of support and an option to buy a third year.

Injunction Covers Support Until August 3, 2026

T-Mobile said Broadcom would not let it extend support for a third year after Broadcom bought VMware, stopped selling perpetual VMware licences and moved customers towards subscriptions and product bundles.

An August 2025 filing from T-Mobile said the company tried to extend support for a third year for $5,288,398.45.

Ars Technica reported that the injunction covers the period from October 2025 to August 3, 2026 at a $5.28 million support price, with a $500,000 undertaking also required.

T-Mobile is now seeking a declaration that it was entitled to renew support services, along with further relief that the court deems necessary.

Broadcom And T-Mobile Dispute Support Costs

Ars Technica reported that T-Mobile later put forward $20 million for a two-year package of support and software updates.

Its stated reasons included litigation costs and the need to reduce interruption and security risks affecting the network and business.

Broadcom said in a filing last month that it had incurred $24 million in costs to support six VMware products for T-Mobile and assign three dedicated support account managers.

T-Mobile responded that it does not use three of the six products and had opened only two service cases this year.

Ars Technica also named other VMware support disputes involving large customers.

The Ars Technica named a privately settled Broadcom case with AT&T and an ongoing case with Tesco over VMware support.

Public Comments Remain Absent

A Broadcom lawyer said in an October 2025 hearing that thousands of customers had migrated to subscriptions and that T-Mobile was an outlier in litigation.

T-Mobile's filings put the dispute around support renewal, migration workload and operational risk rather than only software pricing.

The public record still lacks a final court declaration, a completed migration date or a post-August 3, 2026 support arrangement.
