I've been travelling in Canada and wondered why my phone's data plan was so fast. Turns out that sometime in the last year, T-Mobile improved their international roaming to run at full rate (instead of intentionally degraded 128kbps) in Canada and Mexico, plus added free unlimited calling from those countries, just like in the US. Okay then.
I'm still a little squinty eyed at "binge on" but even with that violation of strict net neutrality, I haven't been able to figure out a way it's bad for consumers, and it's a massive aid when it comes to Digital Divide.
I am unreasonably pleased with this service.
