Connects to EsimTao's travel eSIM reference data. Muse can estimate daily and total GB for a trip, check whether a specific phone or tablet model supports eSIM by region, suggest a plan type for 180+ destinations, resolve regional bundle coverage, and walk through QR or manual installation steps.

Example request: "I'm going to Japan for 10 days with my iPhone 15 and I'll use maps and some video, how much data do I need and which eSIM plan fits?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use EsimTao to help me. It is a free service with an MCP server at https://esimtao.com/api/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.
