For years, the travel eSIM market was easy to understand. A traveller needed data abroad, opened an eSIM app, compared plans, bought a package and installed it.

That model is not disappearing. But the more important B2B story is happening one layer above it.

Increasingly, the company selling connectivity is not trying to become an “eSIM brand” at all. It is a bank, airline, retailer, OTA, loyalty platform, insurer or mobility company that already owns the customer relationship. The eSIM is simply another feature inside the product.

That sounds like a small distinction. It is not. It changes distribution, customer acquisition, pricing power and, eventually, who owns the travel-connectivity relationship.

A banking app already handles FX, cards, insurance and lounge access. An airline knows where you are flying and when. An OTA knows the destination and often the rest of the itinerary. A loyalty app already has identity, payment details and a reason to bring the customer back.

Connectivity suddenly fits into places where it once looked like a standalone purchase.

The customer base matters more

Revolut was one of the clearest early signals. Its travel eSIM sits inside the same app customers already use for money abroad, with the service supplied through 1GLOBAL. Revolut’s own product now places eSIM inside a broader travel layer alongside features such as nearby ATMs and travel benefits.

N26 is moving in the same direction. Its Travel eSIM is available inside the N26 app across its markets. In Germany, it has gone further with a full digital mobile plan running on Vodafone’s 5G network.

Monzo offers another variation. Monzo Mobile is a full mobile service integrated into the bank’s app and tied to the customer’s banking identity, with roaming managed as part of that relationship.

And retail is entering the same territory.

In April 2026, 1GLOBAL announced a strategic partnership with Schwarz Group companies that includes Lidl. Lidl Plus users are expected to be able to purchase eSIM plans directly inside the loyalty app, while Schwarz Group is also taking a 9.9% stake in 1GLOBAL.

That is a bigger signal than another travel-eSIM launch.

Lidl does not need to persuade consumers to download a new connectivity app. It already has the app, the brand recognition, the payment relationship and the customer traffic.

Distribution is becoming the product

This changes the competitive picture.

Traditional travel-eSIM brands such as Airalo, Holafly and Nomad eSIM have built businesses around acquisition: SEO, paid media, affiliates, travel content, app installs and repeat purchases. Their strength is that consumers actively looking for travel connectivity already recognise the category.

Embedded distribution attacks the problem from the opposite direction.

A bank does not need to win a Google search for “best eSIM Japan”. An airline can surface connectivity after ticket purchase. An OTA can place data next to an airport transfer. A retailer can attach an eSIM to loyalty rewards.

The acquisition economics can therefore look very different.

This is why the infrastructure players matter.

1GLOBAL’s Connect platform, for example, is built to let partners sell connectivity through their own apps, websites or bundled products using APIs and SDKs.

The visible brand may be a bank. The telecom layer underneath may belong to someone the traveller never sees.

Convenience is not enough

Embedding an eSIM does not automatically make the offer better.

Travellers still care about network quality, usable coverage, hotspot rules, pricing and what happens when activation fails after landing. Specialist eSIM brands can still be stronger here because connectivity is their whole product. They can offer more destination-specific plans, explain network choices better and serve heavier data users.

Embedded offers are also not ideal for everyone. Someone comparing multiple networks, looking for unlimited data, needing voice or SMS, or managing several destinations may still prefer a dedicated provider. N26’s Travel eSIM and Revolut’s travel offer, for example, are currently data-only.

There is another issue: transparency. If connectivity sits deep inside a bigger app, customers should still be able to understand who provides it, what networks are used, what the conditions are and who handles support.

Convenience should not become opacity.

The real B2B battle

The useful comparison is no longer simply Airalo versus Holafly, or one reseller versus another.

It is specialist distribution versus embedded distribution.

On one side are brands whose main reason for existing is travel connectivity. On the other are companies that already own a much larger customer relationship and can add connectivity almost as a utility.

GSMA commentary on the 2026 market says eSIM has entered a scale phase, with activation and distribution moving closer to the end user and creating room for fintechs, MVNOs and digital travel brands to embed connectivity directly into their products.

That may matter more than another round of cheaper travel-data plans.

Conclusion

Travel eSIM is gradually becoming less of a destination and more of a component.

The winners will not necessarily be the companies with the most recognisable eSIM logo. They may be the platforms that know when the customer is travelling, already have permission to charge them, and can place connectivity at exactly the right moment.

That does not make standalone providers obsolete. It raises the bar. They need to be better at specialist service, flexibility, pricing, support and network choice because “we sell eSIMs” is becoming less defensible as a proposition.

For B2B connectivity companies, meanwhile, the opportunity is shifting from selling another branded storefront to becoming invisible infrastructure inside somebody else’s ecosystem.

The future competitor to a travel-eSIM brand may not look like a telecom company at all.

It may look like a bank, an airline, a supermarket or a booking app.

And if that company already has tens of millions of active customers, the balance of power changes very quickly.
