1GLOBAL
Connect API. Data-only eSIM plans on 1GLOBAL's network, ordered and activated for a subscriber. 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.
