WASHINGTON, Dec. 17, 2025 – T-Mobile announced Wednesday it had launched an online version of its carrier switching tool, after a federal judge blocked the company from using the original beta in-app version.

AT&T had asked for a restraining order preventing T-Mobile from using the beta version of its Easy Switch tool, which was introduced in the company’s app in November. It had asked users to log into their AT&T or Verizon accounts, then used that information to recommend a T-Mobile plan and entice them to switch right from their device.

By Nov. 26, when AT&T first sued, T-Mobile had already altered the tool to ask users to upload a copy of their bill, rather than log into their account directly – that’s also how the new web version works.
