According to https://www.theverge.com/circuitbreaker/2016/7/12/12159210/google-project-fi-three-network-international-roaming-speed , Project/Google Fi added 3/Hutchinson as a native carrier in the UK in the same way that Sprint/T-Mob/US Cellular networks provide service in the US.
One of Hutch's subsidiaries probably provides service almost everywhere in the world (except, oddly, Mexico, last I looked). But whether there's a Google/Hutch tie-in in that market another matter. A Fi data SIM should work in any Google-supported market though. Checking the bands used by the local markets (and/or the prospective device) might be a good idea. Think I've had Fi for 4 years now. Stepping off the plane and your phone Just Works is kind of magical. You can only activate a voice SIM in a Fi-supported phone - but the SIM will work if transferred to another phone once activated, you just may have fewer radios & lose functionality (like transparent in-call handoff between multiple carriers).
