eSIM API for business

Sell our eSIMs under your own brand. One REST API, wholesale pricing, prepaid balance.

Built for resellers, travel agencies and platforms

Browse the full catalogue, issue an eSIM in a single call, and get the activation code back immediately. Your customers never see us — you set your own retail price and keep the margin.

Wholesale pricing

A negotiated discount off our public price on every package, applied automatically to every API call.

Instant delivery

Orders return the ICCID, activation code and install links straight away — no queue, no manual step.

190+ destinations

Country, regional and global plans, including unlimited day passes, covering over 190 destinations.

Refunds on unused eSIMs

If your customer never installs it, refund the order through the API and the money returns to your balance.

Prepaid balance

Top up by card whenever you like. Every order, refund and deposit is itemised in your ledger.

Signed webhooks

We tell you when an eSIM activates or expires, so you never have to poll for status.

Business API questions

Who is the Business API for?

Travel agencies, tour operators, online travel platforms, telecom resellers and any business that wants to sell eSIM data plans to its own customers under its own brand.

What does it cost?

There is no setup fee and no monthly fee. You pay a negotiated wholesale discount off our public retail price on every package you order, and you choose your own retail price.

How fast is delivery?

A single API call returns the ICCID, the activation code, a QR code and the install links immediately. There is no queue and no manual approval step.

How do I pay for orders?

The account runs on a prepaid balance. Top up by card from €100 upwards, and every order, refund and deposit is itemised in your ledger.

Can I refund an eSIM?

Yes. If your customer never installed the eSIM, you can refund the order through the API inside the agreed window and the money returns to your balance.

Which destinations are covered?

Over 190 destinations, with country, regional and global plans, including unlimited day passes. The full catalogue is available through the API.
