For a typical 5 to 7-day Norway trip covering Oslo, Bergen, and the Norway in a Nutshell fjord route, 10 GB to 20 GB is enough for most travelers. A 10 to 14-day trip adding Lofoten, Tromsø, or a Hurtigruten coastal cruise with daily Google Maps, photo uploads, and Aurora-tracking apps usually needs 25 GB to unlimited. Heavy users uploading content from the fjords or working remotely from Bergen cafés should pick the unlimited plan. Hotspot and tethering are typically allowed on fixed-data plans for sharing connection with a laptop or another phone — confirm specific plan rules in the spec.
