Band 12 fulfills the same role in some areas, and is supported on most phones, but T-Mobile doesn't have a nationwide license for it.
With Wifi calling + texting, you can even use your US number internationally since it will work off the eSim data.
Also, Google Fi kinda sucks. They used to be the cheapest, but nowadays you can get better prices from other services. For example, Google charges $10/gb/mo, whereas Mint Mobile (another T-mobile MVNO) charges 4gb for $15/mo, or $30 for unlimited.
Google Fi is only cheaper if you use less than 1.5gb of data per month, and the service quality is probably the same.
...and that's not even mentioning all the privacy concerns attached to Google.
It's exciting to watch how many years in a row they can stay at $10/GB, and not in a good way.
Fi caps out at $60/mo (so 6gb), after which you get unlimited data for "free". However, you only get 15gb of high priority.
I think Fi is trying to take advantage of the Google brand to sell MVNO service at a crazy markup.
My car has an "unlimited" plan with AT&T, and holy crap, it's worthless. If I actually need to do something, like, now, usually I have to turn off my phone's wifi if the car's on.
And this isn't me modifying my behavior. If I had a habit of watching YouTube or Netflix from all over the place, I'd get a different phone plan. I'm not like penny pinching here. It's just that my current phone plan works, I like how easy it is to administer, and switching providers in a huge PITA for a family of 4, so something else better be damn good.
Fi does not feed usage information or otherwise into the ad machine. See the privacy notice on https://fi.google.com/about/tos/
I'd do Cincinnati Bell in a heartbeat, if I could.
Plus, it's primarily the T-Mobile network anyways with the addition of the US Cellular network and the old Sprint network.
Sure, people can't call me on my usual number, but I see that as an additional benefit. I'm on vacation.
I love to travel, and nothing beats being able to land in (pretty much) any country in the world, turn on your phone and have working service just like that. No SIM cards, no different numbers, no local pre-paid cards, and no crazy international fees.
As someone who enjoys work/travel for weeks to months at a time, every other major carrier is not feasible for this (think 10$/day, which becomes unreasonable when you're out of the country for 3+ weeks).
Unless somebody else could recommend another option it seems I'm stuck with T-Mobile for now.
