The $20.00 premium connection package, what dose T-Mobile mean by "Unlimited data in 140+ global destinations at twice the speed" ? Will I have data caps if I purchase the add-on package?

I'm thinking that this question is about the $25 per line add-on, ONE Plus. The side by side comparison shows that on ONE, there's a max possible international roaming data speed of 128 kbps, but with ONE Plus, those top possible speeds increase to 256 kbps.
