I might be mistaken then, but doesn’t part of Net Neutrality mean that telecommunication companies can’t throttle unlimited plans?

I used the phone app and started a chat. Here’s what I asked, and their response:

T-Mobile users; be aware that T-Mobile has prepared for this and are trying to automatically transition grandfathered accounts with unlimited everything into their new plans.

I’m not 100% sure if the coverage of the new plans are technically worse, but they’re definitely more expensive. And I wouldn’t be surprised if the new plans had contact language to do a rug pull in the future.

You need to opt out of the transition.
