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. This page does not publish a rate card.

1. Set your agent up, once

In your agent's chat

set up Ancilair — https://ancilair.com/llms.txt

2. Ask for the job

The prompt

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.

Why this prompt works

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.

Why go through Ancilair

One token. Supplier credentials stay on the server.
The price is quoted on the call, at the supplier's rate, with 0% markup.
A key the team already holds is never metered, and it wins over Ancilair's account.
A named supplier is a different tool id, not a new integration.
