The three eSIM platform business models

Why the feature list is the wrong comparison

Comparing eSIM reseller platforms feature by feature produces a spreadsheet in which everything looks roughly the same. They all offer a branded storefront, an API, instant QR delivery and coverage in a hundred-odd countries. Reading that spreadsheet, you would conclude the market is commoditised and pick on price.

The spreadsheet is hiding the only question that compounds: who decides what you pay for each eSIM you sell? Answer that and the market collapses into three business models. Two of them answer "we do", and neither advertises it.

A useful shorthand: features determine what your store can do this month. The business model determines what your margin looks like in year three.

Model A — the wholesaler

The oldest and largest group. The platform holds the carrier relationships, buys connectivity at scale, and sells it to you at a wholesale rate. You resell their telecom relationship under your own brand.

Companies operating primarily this way include eSIM Access, eSIM Go, Roamic, zendit, eSIMCard, Telnyx and a long tail of regional distributors. Coverage is genuinely deep, the catalogues are large, and the carrier deals behind them are real.

What you are actually buying

• Access to a catalogue you could not assemble yourself without signing many agreements.
• Someone else carrying the telecom relationship, the commitments and the compliance.
• A wholesale price they set, which is your cost of goods forever.

That third line is the trade. It is not a criticism — it is the deal, and for many resellers it is a good one. But your margin is whatever they leave you, and it changes when they decide it changes.

Model A is moving. eSIM Access now publishes a product that connects your own Stripe account and lets you sell from their catalogue with your own markup — bring-your-own-payments, without bring-your-own-supply. Watch for this: “your own Stripe” is becoming table stakes and is not the same claim as “your own cost of goods”.

Model B — the “free” platform

Structurally a wholesaler with the subscription line deleted. There is no monthly fee, no setup fee and no revenue share. You pay only the wholesale cost of each eSIM you sell — a cost they set, on a catalogue only they supply.

The economics are simple once stated plainly: the platform’s margin is inside the $0.70, it is charged on every order you will ever process, and it grows in absolute terms exactly as fast as your business does. A subscription does the opposite — it shrinks as a share of revenue as you grow.

This model genuinely wins at low volume, and it is the right answer for someone testing whether anyone will buy at all. It is the marketing that is the problem, not the pricing.

Model C — the orchestrator

The newest of the three and still the smallest. The platform never buys an eSIM and never holds a payment. You connect your own provider account and your own payment account; the software sits between them, running the shop.

Esimbit works this way, and so — in a narrower form — does eSIM Panel. The defining property is that your cost of goods is a number you negotiated with a supplier directly, which means you can audit it against a second quote.

The last row is the real cost of Model C, and it is not small. You have to apply for a provider account, agree terms and hold that relationship yourself. If you do not want to do that, Model A is genuinely the better answer and you should not be talked out of it.

Which one you should be on

The decision is mostly determined by two things you already know about yourself: your monthly volume, and whether you want a supplier relationship.

1. Selling under ~200 eSIMs a month, or still testing demand: Model B. The embedded markup is cheaper than any subscription at that volume, and you have not yet earned the right to care.
2. Any volume, and you actively do not want to hold a provider account: Model A. Pick on catalogue depth and support quality rather than headline margin.
3. Past a few hundred orders a month, and willing to hold a supplier relationship: Model C. This is where the embedded markup starts costing more than a flat fee, and where owning your rate compounds.
4. eSIMs are a feature of a larger product you already run: talk to Model A wholesalers about a direct API, or run Model C with your own keys. The storefront layer is the part you do not need.

One thing worth saying plainly, since we are Model C and therefore not neutral: if you are at fifty orders a month, we are the wrong choice and the arithmetic in our own pillar post says so. Come back at five hundred.
