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

- check_esim_device: Says whether a phone model is likely to take an eSIM (likely, unlikely or check), from the model name, with how to be sure on the phone itself. Call it before buy_esim when the customer is unsure.
