Digital Nomad Visa & eSIM Field Notes — Source-Checking Methodology (2026)

This dataset accompanies the destination-guide research methodology used by Nomad Desk for its digital nomad visa and eSIM briefings. It documents how visa-free tourist entry windows are distinguished from formal digital nomad visa programs, how the Schengen 90/180-day rolling window is counted, and how eSIM plans are compared across regions for long-stay travelers. A worked destination example, the Japan digital nomad visa guide, is available for reference. Full dated, sourced destination briefings are published at nomadbriefing.com, including guides for Japan, Portugal, Thailand and Mexico, plus a comparison of eSIM options for long trips.
