US citizen here. I was in Mozambique, England, Romania and Denmark with my Fi phone in 2017. Despite being listed as a country Fi covered, I could never get service in Mozambique (Beria), despite spending a few hours with several courteous Google Fi customer support people. My experience in the European countries was satisfactory. I don't recall any issues and it was nice to have my US phone number just work in those places.
An earlier trip in 2016 to Tajikistan in central Asia with my Fi phone required purchasing a local SIM card.
I've since given up on Google Fi and switched my number back to Verizon and have been happily using a $200 Moto G5 Plus purchased through Amazon.
