# Pick an eSIM

Status: pre-launch. Open-source self-hosted version and Ancilair Cloud are coming; join the waitlist at https://ancilair.com/#waitlist.

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.

The open-source, self-hosted version is coming. Contact: https://ancilair.com/contact

- 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 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. HOAM's public MCP returns a checkout link and does not order. Ordering through the partner API is on request.
