T\-Mobile is asking a New York court to rule that Broadcom was contractually obligated to continue supporting its VMware perpetual licenses\.
In its complaint, T\-Mobile said it has tens of thousands of virtual machines using VMware software across approximately 303,140 CPU cores\. It also said that it was migrating off VMware but noted the[time\-consuming and technical challenges](https://arstechnica.com/information-technology/2025/01/a-long-costly-road-ahead-for-customers-abandoning-broadcoms-vmware/)involved in migrating over 1,000 applications\.
It filed its lawsuit, which was first reported by[The Register](https://www.theregister.com/virtualization/2026/07/01/t-mobile-appears-to-be-quitting-vmware-and-fighting-a-very-familiar-battle-for-support-rights-on-the-way-out/5264750)today, in the Supreme Court of the State of New York in August 2025[\(PDF\)](https://cdn.arstechnica.net/wp-content/uploads/2026/07/654741_2025_T_Mobile_USA_Inc_v_Broadcom_Inc_et_al_COMPLAINT_58.pdf)\.
The mobile company claimed that in 2023, it bought perpetual VMware licenses, plus two years of support with the option to buy a third year\. But after Broadcom bought VMware, it stopped sales of[VMware perpetual licenses](https://arstechnica.com/information-technology/2025/07/some-vmware-perpetual-license-owners-are-unable-to-download-security-patches/)in favor of subscriptions and started bundling VMware products into a few, more expensive bundles\.
When T\-Mobile tried to extend support for a third year 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 available of all perpetual products, which includes Stated Out Year 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 as the court deems necessary\.
Tesco is migrating 40,000 server workloads away from VMware, citing Broadcom's abusive conduct and excessive price hikes, as a legal dispute over pricing continues.
Tesco sues Broadcom (owner of VMware) and reseller Computacenter for breach of contract over VMware licensing changes, seeking £100 million in damages and warning the dispute could disrupt grocery supply.
Allstate accuses Broadcom of launching retaliatory audits after it terminated its VMware and CA contracts, highlighting ongoing legal battles between Broadcom and disgruntled enterprise customers.
HPE is offering a year of free VM Essentials software to entice VMware customers to migrate, though some partners express skepticism about its impact due to hardware constraints and limited partner incentives.
T-Mobile is retiring many legacy plans, including some from the 3G/4G era and Sprint, and moving subscribers to current plans, with some seeing price increases. Customers are upset due to T-Mobile's past promises as the 'Un-Carrier'.
