Every week, a new eSIM provider seems to enter the market—and with them, another promise to “redefine travel connectivity.” Partnerships are multiplying just as fast, reflecting how vital seamless mobile data has become for the travel and events industry. Amid this crowded space, one new collaboration genuinely stands out: Evintra, the global B2B directory for the MICE and tourism sector, has joined forces with World Mobile, developer of the world’s first unlimited global data travel eSIM, as it is written on their website.

This partnership doesn’t just add another logo to the list. It introduces a plug-and-play connectivity solution that finally feels built for professionals—one that covers 120+ destinations, connects automatically to 250 networks, and gives travel companies a simple, revenue-positive way to keep their travelers online everywhere.

What’s actually new here

Evintra’s network spans 180+ countries and hundreds of thousands of industry pros; World Mobile’s proposition is a single eSIM that auto-roams across ~250 networks in 120+ destinations with unlimited 5G/4G data. Evintra’s members get access through a partner portal to issue, track, and monetize eSIM activations—useful whether you’re an agency, DMC, venue, or event organizer who wants fewer “Wi-Fi drama” emails and a small but real ancillary revenue stream. World Mobile’s “Unlimited eSIM” snagged an ITB Innovator 2025 nod earlier this year, which helps cut through the usual eSIM noise.

How it works in a show setting

At WTM London (4–6 November 2025, ExCeL), visitors will be able to experience World Mobile’s unlimited eSIM firsthand with a complimentary trial credit. The setup is simple: activate the eSIM in seconds and stay connected across the venue without relying on patchy Wi-Fi or roaming fees. For hosted buyers, exhibitors, and event organizers, it’s a practical demonstration of how effortless connectivity can enhance both travel and event experiences.

Why this matters to travel pros (beyond the buzzwords)

eSIM for travel is rapidly shifting from a convenience to an expectation. Juniper Research projects that the number of travel eSIM users will climb from roughly 40 million in 2024 to over 215 million by 2028 — a fivefold increase that reflects how quickly digital connectivity habits are changing. For travel and MICE professionals, that’s a clear signal: travelers now assume seamless mobile data is part of the experience, not an upgrade. Companies that integrate eSIM solutions can simplify operations, deliver smoother customer journeys, and stay relevant in an increasingly digital-first market. After all, traditional roaming remains one of the most frustrating—and costly—parts of international travel, making reliable alternatives more than just a nice perk.

The business case—and why it matters

For travel professionals, this partnership goes beyond adding another tool to the stack. Evintra’s new partner portal, powered by World Mobile is designed to make eSIM distribution practical — not promotional. It gives agencies, DMCs, and event planners a simple way to issue and monitor eSIM activations, track usage, and understand performance in real time.

That kind of transparency is valuable: it allows companies to offer global connectivity as part of their travel packages or event experiences without managing inventory or fielding endless “my SIM doesn’t work” messages after landing. The eSIM setup takes seconds, requires no shipping, and scales instantly.

Because World Mobile’s unlimited data eSIM operates across more than 250 partner networks, the result is often more reliable coverage than single-carrier roaming or venue Wi-Fi—especially during major conferences or events when local networks can be saturated.

Who it’s not for

This isn’t a one-size-fits-all solution. Companies already running global roaming through negotiated enterprise contracts will see fewer benefits—those programs already have predictable pricing and throttling rules. Similarly, for low-data travelers who just need messaging and navigation, a regional prepaid eSIM might remain the cheaper, simpler choice. And of course, itineraries that go beyond World Mobile’s 120+ supported destinations should double-check coverage before committing.

What could be improved?

Even strong ideas have weak spots. The “unlimited” label in mobile data is always open to interpretation. Clearer communication around fair-use thresholds—ideally published by destination—would help event organizers and corporate travel teams plan more accurately.

For large-scale deployments, API access would also make a difference. Integrating eSIM activation directly into existing booking or registration systems could turn this from a smart add-on into a true infrastructure upgrade. Finally, more independent performance data (from firms like Opensignal or Ookla) comparing travel eSIM speeds with carrier roaming would strengthen credibility and help procurement teams justify adoption.

Alternatives to explore

Several established travel eSIM players offer their own advantages. Airalo, Airhub, Nomad, YESIM, Ubigi, and GigSky all provide global coverage through fixed data bundles, often at competitive rates for lighter users. Others, like Roamless, use multi-network connectivity but apply stricter “unlimited” definitions. And while traditional carriers such as T-Mobile or Verizon still bundle international data passes, those plans tend to cost more per gigabyte and often slow down after usage thresholds.

The market context—and why timing is on their side

Event connectivity has become mission-critical. Hybrid sessions, app-based ticketing, and AI-powered matchmaking — all depend on fast, stable data. Yet even high-profile venues struggle with Wi-Fi reliability once thousands of delegates go online at once. That gap has created an opening for travel eSIMs to become part of the event toolkit, not just a traveler’s backup plan.

Industry analysts forecast explosive growth: Juniper Research estimates the number of travel eSIM users will rise from 40 million today to over 215 million by 2028. For MICE professionals and travel suppliers, that’s a strong signal that mobile data is no longer an afterthought—it’s part of the product.

Conclusion—a credible step forward for professional connectivity

World Mobile’s unlimited globaI eSIM, paired with Evintra’s vast network, hits a realistic sweet spot: it solves a real pain point and gives travel companies a scalable way to modernize their service. It’s not revolutionary, but it is timely and well-executed—especially compared to retail-focused competitors that rarely cater to B2B workflows.

The caveat is in the details. As with any “unlimited” offer, fair-use limits and speed management need transparency. But overall, the partnership represents a meaningful evolution in how the MICE and tourism sectors approach connectivity — not as a side perk, but as part of the traveler experience itself.

If eSIM adoption continues its current trajectory, partnerships like this one could soon define the industry standard for professional mobility.
