eSIM Go
Wholesale travel-eSIM API. The catalogue lists bundles. A validate order checks a bundle without buying it. A transaction order buys it. Job: Pick an eSIM. 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.
You use your own supplier key or OAuth. Ancilair does not bill that call.
Brands and logos belong to their owners. Listing does not imply a partnership.
