The difference is in quality. I am also right now in Sydney, on the last day of my week-long business trip, and I have had constant 4G connection with Google Fi. Back when I had T-Mo I needed to find WiFi whenever I needed to download a large attachment, and obviously whenever I wanted to stream videos. Now I don't even ask for the WiFi password. And yes, I'll be watching Game of Thrones this evening using my phone's hotspot which has a US IP, so I can really feel at home. I'm disappointed to hear that Google's customer service is bad, but when I signed up I wasn't even sure if they had a customer service department. T-Mo's support was OK, but for the past few months I've been living without it just fine.
