Had this when I first got my Fi SIM. The first activation must be in the US where they can contact the base network they use which I think is tmo.
After that I haven't had the issue, but now and then I have to move the SIM from my iPhone to my Pixel to get on a new network when I arrive in a new country. This isn't always the case. For instance I flew from Tokyo to Singapore via Seoul. When I landed in Seoul it worked fine, landed in Singapore and couldn't get a network until I popped it into my Pixel and then back into the iPhone.
