just thought I would update this with my recent Google fi experience.
as I posted before my international data was suspended. I ended up with a second local sim card for data and it was fine. later on, I was in the US in October for almost a month and I thought by doing so it would have reinstated my international data. turns out, it didn't. I learned today after landing in Europe that it's still suspended. I tried with the help desk but they insisted it cannot be reversed as it's an automatic system action to block you if it's abused and will only get reinstated by the system if you spend a few months or more in the US again. one month isn't enough.
so, be warned that once you end up on the shit list, you're gonna have a hard time getting off it!
