We are witnessing a big change in how modern travelers prepare for international journeys, moving away from searching for physical SIM cards at airport kiosks towards a reality where staying connected is much easier. Year by year, the days of landing in a foreign country without a reliable connection are fading, and the data shows this shift is happening at an accelerating pace.

According to the Holafly 2026 Summer Travel & eSIM Report, overall eSIM adoption has surged to 28.1% for the upcoming summer season, representing a 9.1 percentage point increase from the 19.0% of travelers who used the technology during their trips in 2025.

However, while this global trend is undeniable, the real story appears when we break the data down by region, uncovering interesting paradoxes and identifying clear regional leaders.

What region is leading this global trend?

Picture a traveler stepping off a long-haul flight in Seoul or navigating the bustling streets of New York, instantly connected to high-speed data before they even reach the baggage claim carousel; this is no longer a futuristic scenario, but the current reality for travelers originating from Oceania and the Asia region.

According to Holafly’s research, Oceania is currently leading the global eSIM adoption by a noticeable margin, and the Asia region follows closely behind, driven heavily by mature markets where digital habits are well established among consumers.

To truly understand how the rest of the world is shifting, we can look at the intended adoption rankings across all major regions to see where the strongest growth originates from:

• Oceania leads the global market with a 40.2% intended adoption rate.
• Asia follows closely, with 34.6% planning to adopt.
• North America sits firmly in the middle tier, posting a 26.5% adoption level.
• Latin America closely trails North America, with a 25.8% adoption figure despite economic constraints.
• Europe lags behind other developed regions, with only 21.8% intending to adopt, mainly because of its Roam Like at Home policy.

Interestingly, travelers originating from the Asia region are not primarily adopting eSIMs to avoid roaming costs. Instead, convenience is the main driver: 76.5% cite easy activation as their top reason for choosing an eSIM, while only 28.6% mention avoiding roaming fees.

This suggests that in digital markets, people prefer simple, easy-to-use solutions, showing how other markets may evolve and consume digital connectivity over time.

Why does North America not meet its full potential?

For a traveler based in the United States or Canada, crossing a border brings concerns about what their phone bill will look like when they get back, and despite facing some of the highest international roaming fees, North American travelers remain among the least aware of eSIM technology.

As the research shows, the primary motivations for North American travelers are deeply rooted in financial pain and digital security, with 52.9% actively seeking to avoid carrier roaming fees and 50.4% wanting freedom from unreliable public Wi-Fi networks.

North America represents one of the biggest untapped opportunities for eSIM adoption, with nearly half of US travelers (49.5%) and almost four in ten Canadians (39.6%) saying they didn’t know about eSIMs before travelling, making lack of awareness the region’s biggest barrier to adoption.

Yet despite this, eSIM usage has already reached 24.6% in the United States and 30.5% in Canada. The contrast suggests that demand already exists once travelers become familiar with the technology. In other words, the biggest challenge is not convincing people to use eSIMs, it’s making them aware that the option exists.

With lack of awareness remaining the biggest barrier for 46.6% of North American travelers, millions are still relying on expensive roaming or unsecured public Wi-Fi simply because they are unaware of eSIMs.

The good news is that this barrier is relatively easy to overcome. Once travelers discover eSIM technology, they can activate a data plan before departure and avoid relying on expensive roaming or unsecured public Wi-Fi when they arrive.

How Europe’s eSIM adoption changes the moment travelers leave the EU

At first glance, Europe appears to be lagging behind the rest of the world in eSIM adoption, with just 22.5% of European travelers using an eSIM. But looking at Europe as a single market hides what is really happening.

The turning point comes when European travelers leave the European Union: within the EU, where “Roam Like at Home” allows people to use their domestic mobile plans across member states, eSIM adoption stands at just 19.9%. However, for Europeans travelling beyond the EU, adoption more than doubles to 44.8%, one of the highest levels seen in the entire study and comparable to Oceania, the world’s leading region.

In other words, Europe does not have an eSIM adoption problem, but a roaming regulation that removes the need for one on most short-haul trips. The findings also explain why Europeans choose different connectivity solutions depending on their destination: within the EU, traditional roaming remains the default choice because it is simple, familiar and free under current regulations, but once travelers head to destinations in other regions that advantage disappears, making eSIMs a far more attractive option.

The barriers also change dramatically, as for those travelling outside the EU lack of awareness becomes the main challenge, with 28.3% saying they did not know eSIMs existed. As the cost advantage of free roaming disappears, awareness, not regulation, becomes the factor limiting adoption.

Uncovering the actual eSIM adoption picture

Regional differences show that travelers prepare for international trips in different ways, influenced by local regulations, mobile markets and varying levels of digital awareness.

However, despite these local differences, the global trend is clearly moving in one direction, especially when we look at the year-on-year surge in travelers ditching their old physical SIM cards to embrace digital solutions instead.

With overall intended eSIM adoption jumping by a 9.1 percentage points compared to last summer, it is clear that staying connected is becoming increasingly important for international explorers, and reliable options like Holafly are stepping in to make that transition smoother than ever before.
