FAQ

eSIM API Questions

Integration, pricing, and launch - the essentials for building on Bappy.

An eSIM API is a set of REST endpoints that let your software provision, activate, and manage digital SIM profiles programmatically. Instead of building carrier integrations yourself, you call the API to activate a data package and receive a QR code for your customer. Bappy is OmaxTelecom's eSIM reseller API - covering 200+ countries with package-based plans.

Sign up at console.omaxtelecom.com, get your sandbox API key in minutes, integrate Bappy's REST API into your app or website, and switch to production when ready. There is no setup fee and no platform monthly fee. Production requires a prepaid wallet with a €100 minimum top-up. Activations are charged at wholesale rates. There is no monthly link fee in the first calendar month of a new link. From the second month onward, €0.09 per month is charged only while the link remains active. Outbound SMS is €0.01 per message. You set your own retail prices.

Choose the eSIM API (Bappy) if you have a developer and want to embed eSIM purchasing into your existing app, booking flow, or platform. Choose the white-label store if you want a turnkey branded storefront on your domain with no coding. Many partners start with one and add the other later.

Most integrations go live in under 7 days. Sign up, get sandbox credentials instantly, integrate with our RESTful JSON API, and switch to production when ready.
