When I was in Austria a couple of years ago I had my phone but no local SIM. It was still invaluable to me: * I took a photo of the subway map to refer to later * I had Google Maps in offline mode, while showed my location but no/few labels. So I still got to explore and discover: “this building is an interesting shape, I’ll go check it out” * My photos of course, which I also cherish
