Compares eSIM data plans from many providers for any destination. Filter by trip length, data amount, budget, and features like 5G or phone number. See prices, coverage, networks, and buy links. Check if your device supports eSIM.

Example request: "Find me the cheapest eSIM plan for a week in Japan that includes a phone number."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use esimdata to help me. It is a free service with an MCP server at https://esimdata.app/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- search_plans: Find travel eSIM data plans for a destination from every provider esimdata tracks, ranked neutrally by price (or price per GB, or validity). Filter by trip length, data, unlimited, needs (hotspot, 5G, phone number, top-up, no ID check) and budget. Each result has a buy_url to the
- get_plan: Everything esimdata knows about one plan (by the id search_plans returned): all countries it covers, networks, policies, the provider's own page, the buy link and its price history.
- compare_plans: Put 2 to 10 plans (ids from search_plans) side by side with the same fields, in the order given, to help a traveller choose.
- country_overview: A destination at a glance: how many plans and providers, the cheapest plan, the cheapest per GB, and which mobile networks the providers say they use there.
- check_phone: Check whether a phone, tablet or watch model supports eSIM, from the manufacturer's own published list (with regional exceptions, e.g. models sold in mainland China), with the source link.
- list_providers: Every eSIM provider esimdata compares, with its website and whether esimdata earns a commission when a traveller buys through it (ranking never depends on it).
