T-Mobile's new "unlimited" data plan may breach US net neutrality rules, campaigners have said.
US authorities barred internet service providers from blocking access or speeding it up for a fee. Jeremy Gillula, the senior technologist at the foundation (EFF), told the Daily Dot that, while the organisation was still in the process of gathering information, "from what we've read thus far it seems like T-Mobile's new plan to charge its customers extra to not throttle video runs directly afoul of the principle of net neutrality".
