You book flights, hotels, tours and transfers for your clients. Somewhere on that list, more of them now ask the same thing: "Will my phone work when I land?" You can answer that — and earn from it — without holding stock, signing a wholesale contract, or hiring a developer.
Here's the honest version most "become an eSIM reseller" guides skip: a small travel agency doesn't need a reseller platform, a funded wallet, or an API to offer eSIM. Those are tools built for companies whose whole business is selling connectivity. For an agency that just wants to add a useful, paid extra to trips it already books, the simplest path is turnkey: you put your name on it, and someone else runs everything behind it.
This guide clears up the jargon, then helps you pick the right setup by one honest measure — how much work it actually takes.
An eSIM is just a travel data plan that installs on a phone by scanning a QR code — no physical SIM card, no shop, no queue at the airport. If that's new to you, our beginner's guide to how an eSIM works explains it in plain terms.
For your agency, "offering eSIM" can mean something as light as sending clients a link, or as branded as giving them a data-plan page with your logo on it. What it does not have to mean:
If those four are what's been putting you off, good news: they're optional, not required.
There are really three models. The big platforms tend to lead with the most technical one because that's what they sell. We'd rather you start with the one that fits your team. Here they are from least to most work:
| Model | Effort | Your brand? | Tech needed | Who runs payments, support & fulfilment | Best for |
|---|---|---|---|---|---|
| Affiliate | Lowest | No — our page | None | We do, all of it | You just want to recommend eSIM to clients and earn a cut |
| White-label | Low | Yes — your name, logo, colour, domain | None (no code) | We do — hosting, payments, support, fulfilment | Most small agencies that want it to look like their own |
| API | Higher | Yes — inside your own platform | Yes — your platform + a developer | You run checkout; we supply the eSIMs, wholesale rates & docs | Agencies that already run their own booking site and have a dev |
You get a unique tracking link and a QR code the day you sign up. Share them however you already talk to clients — a booking confirmation email, a WhatsApp message, a line on your itinerary PDF. When a client buys, we handle the sale, the delivery and the support. You see the orders and revenue in a dashboard in real time, and you earn a commission.
Pick this if you want to recommend eSIM without it looking like a product you run.
This is the one most small agencies actually want. You get a branded eSIM page — your business name, your logo, your colour, on your own domain — and it can be online in about a day. There's no code to write, no payment system to set up, and no fees to start. We host it, and we run the support, the payments and the fulfilment behind your brand. You earn commission, paid monthly.
To your client it looks like part of your agency. To you, it's a page you didn't have to build and don't have to babysit.

If your agency already runs its own booking platform or checkout and has a developer, the API route lets you sell eSIM natively inside it. You get custom wholesale rates, a direct REST API with webhooks, full developer documentation and dedicated technical support. This is the "build it into your product" option — powerful, but only worth it if you have the platform and the person to wire it up.
A quick way to decide, without overthinking it:
Most owners reading this land on white-label — it gives you the brand and the revenue without the build. You can start there and move to API later if you ever build your own platform.
Commission is up to 20%, paid monthly. "Up to" is the ceiling, and we'd rather say it plainly than dress it up: what you actually make depends on how many of your clients buy and how much data they need. An agency booking a handful of trips a month will see modest extra revenue; one moving a lot of international travellers will see more. There's no guaranteed income here, and anyone promising you one isn't being straight.
What makes it low-risk is the cost side: with affiliate and white-label there's no inventory to buy, no wallet to fund, and no fees to start, so the downside is basically your time. You're adding margin to trips you're already booking, not taking on a new cost centre.
This is the question that stops most agencies, so here's the straight answer: with affiliate and white-label, we do. Payments, delivery and customer support all sit with us, behind your brand. Practically, support means live chat during business hours plus a support ticket attached to every order — not a 24/7 call centre, but a real team that owns the problem so you don't become tech support for your clients.
No stock, no code, no wholesale contract. If you can send your clients a link, you can offer eSIM.
Do I need to buy eSIMs upfront or hold any inventory?
No. With the affiliate and white-label models there's no stock to buy and nothing to pre-fund. You earn commission on what your clients actually purchase.
Do I need a developer or to integrate an API?
Only if you choose the API model. Affiliate and white-label need zero code — white-label gives you a branded page with no development at all.
How long does it take to go live with my own branded page?
About a day for white-label, once you've sent your name, logo and colour. There's no payment system to set up and no fees to start.
How much can I earn?
Commission is up to 20%, paid monthly. Honestly, the amount depends on your own client volume — how many book and how much data they need. It's extra margin on trips you already sell, not a guaranteed income.
Who supports my clients if their eSIM has a problem?
We do. With affiliate and white-label, payments, fulfilment and customer support all sit with us, behind your brand — live chat during business hours plus a support ticket on every order.
Can I try it before committing?
Yes. There's a live demo at demo.esimstory.com (no signup, no real payment), and applying to the partner program is free with no commitment.
What's the difference between affiliate and white-label?
Affiliate uses our branded page and a tracking link — lowest effort. White-label puts your name, logo and colour on the page so it looks like your own product. Both are commission-based and both are run by us.
You don't need to become a telecom company to offer your clients something they now expect. Point them to a link, or put your brand on a page we run — either way, it's revenue on trips you already book, with none of the stock, code or risk.
