Did NOT Say Unlimited isn't around still
at T-Mobile
Un throttled? Again surely you jest?
Do I need to link articles to throttling practices too?
You weren't very specific in the original post. But as you've confirmed, they did increase plan prices for new users, whereas AT&T increased the cost for existing users while not even offering it to new customers anymore.
And yup. T-Mobile's now $95 unlimited high-speed data is unthrottled, except for the very rare chance that you end up in an extremely congested area.
