How much data do I need for a Sweden trip?

For a typical 5 to 7-day Sweden trip covering Stockholm and a day trip to the archipelago, 5 GB is enough for most travelers. A 10 to 14-day trip adding Gothenburg, Malmö, and a Lapland Northern Lights extension with daily SJ navigation, Google Maps, and casual photo uploads usually needs 10 GB to 20 GB. Heavy users uploading content from Aurora trips or working remotely from Stockholm cafés should pick the unlimited plan. SJ train apps and Swish payments use minimal data, but Aurora videos and high-altitude photo uploads add up.
