About Does It Work In
Does It Work In documents what actually happens when you try to use an eSIM, VPN, foreign credit card, navigation app or AI assistant across borders.
Official claim vs. verified reality
Vendor marketing pages and help centers routinely say a service works in a country while omitting critical conditions: roaming carrier routing, per-transaction passport verification thresholds, fair-use speed throttling, or the fact that an app must be activated before boarding your flight.
Every guide on Does It Work In separates the official vendor statement from verified on-the-ground behavior, lists the exact pre-departure steps required before you leave home, and documents the known failure modes.
How we fund the site
Outbound links under /go/<id> may earn us an affiliate commission when you buy an eSIM plan, VPN subscription, or open a multi-currency account. Commissions never change a service status badge (Works, Conditional, Workaround required, or Blocked).
When a provider works poorly in a destination—for example, standard VPN apps that fail in mainland China or unlimited eSIM plans that throttle hotspot tethering—we state that plainly on the page.
Plain data for people and AI agents
Every guide is available as structured JSON (.json) and Markdown (.md) by appending the extension to its URL, via our public REST API (/api/v1/guides, /api/v1/countries, /api/v1/providers), and over our stateless MCP server at /mcp.
If a carrier rule, app limit, or pricing tier changes, use the "Report outdated info" button on any page or POST to /api/v1/reports.
