# Pick an eSIM

Travel eSIMs from suppliers that sell them through a partner API. The routed ids are anc.esim.plans, then anc.esim.order.

A plan list is not an activated eSIM. This is not telecom advice. Coverage on a plan is the supplier's description of that plan, quoted on the call.

Routed: `anc.esim.plans, then anc.esim.order`.

The price is quoted on the call, at the supplier's rate, with 0% markup. This page does not publish a rate card.

Contract: https://ancilair.com/llms.txt
API: https://api.ancilair.com
MCP: https://mcp.ancilair.com

## What's the best way to ask?

Setup line (paste into any agent): `set up Ancilair — https://ancilair.com/llms.txt`

Then ask: "Using Ancilair, list eSIM plans for France for 7 days. Read https://ancilair.com/llms.txt. Call anc.esim.plans on https://api.ancilair.com. Show the quoted price. Do not order until I say yes."

- One token. Supplier credentials stay on the server.
- The price is the quote on the call, at the supplier's rate, with 0% markup.
- A contract the team already holds is never metered, and it wins over Ancilair's account.
- A quote, a search, a plan list, or a requirements check is not a booking. The follow-up runs only after an explicit yes, with an Idempotency-Key.
- eSIM Go validate is still esimgo.esim.plans. It does not purchase. Ordering is esimgo.esim.order, and only after an explicit yes.
