FAQ

eSIM API Questions

What is an eSIM API?

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.

How do I become an eSIM reseller with an API?

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 are zero setup fees and zero monthly minimums - you pay only for activated SIMs at wholesale rates and set your own retail prices.

eSIM API vs white-label store - which should I choose?

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.

How fast can I launch with Bappy?

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.

Is there a monthly commitment?

No. Bappy has zero monthly minimums, no lock-in contracts, and no volume requirements. You pay only for activated SIMs.

How many countries does Bappy cover?

Bappy covers 200+ countries with package-based eSIM and physical SIM plans, powered by tier-1 carrier backbone with at least two carriers per destination.
