Millions of travellers already have phones that can help them stay connected abroad. They book flights with apps, keep boarding passes in digital wallets, use maps to plan, rely on ride-hailing after landing, and message throughout their trips. But many travellers still do not know if their phone supports eSIM.
This is the main contradiction in travel connectivity. The technology is easier to get, the benefits are clear, and travel eSIM use is growing fast. Still, many travellers are not used to eSIM yet.
That is why the next big opportunity in the eSIM market is not just about cheaper data or wider coverage. It is about closing the awareness gap.
A YouGov survey for Proximus Global/BICS found that only 33 per cent of people in the US, UK, and China know what an eSIM is. Another 42 per cent are not sure if their phone has one. Still, 49 per cent said they would consider using an eSIM while travelling if they understood the benefits.
This gap is important. The problem is not a lack of demand for connectivity, but uncertainty. Many travellers are not sure how eSIM works, if it is right for them, or if they can count on it when they need it.
For years, international mobile connectivity focused on cost. Travellers worried about roaming bills, airport SIM counters, and confusing fees. Travel eSIMs offered a simple solution: buy data before the trip, install it digitally, and connect abroad without changing SIM cards.

That value still matters, but the market is moving into a new phase.
More importantly, the way eSIM is explained needs to change. Travellers do not want technical details. They want simple answers: what to do before the trip, what to expect when they land, and how to stay connected without problems.
GSMA Intelligence says that about five per cent of smartphones worldwide had eSIM by the end of 2025. This is expected to reach 10 per cent by the end of 2026 and double again in 2027. By 2030, there will likely be more eSIM smartphones than traditional SIM ones.
This shows that eSIM is moving from something only early adopters used to a mainstream standard. More phones will support it, and more travellers will have access without needing new devices. But just because devices are ready does not mean consumers are.
A traveller might have an eSIM-ready phone but still hesitate. They might worry if installing an eSIM will affect their main number, if apps like WhatsApp will work, or when to install it. They could also be concerned about activation failing at the airport or losing access to maps. These are everyday worries, not technical problems.
For most travellers, staying connected is part of the trip. It affects how they get around, communicate, book things, and handle daily needs. If setup is confusing, they will likely stick to what they know, even if it costs more. That is why education is now key to the market opportunity.
The travel eSIM market is set to grow fast. Juniper Research says global travel eSIM users will rise from 40 million in 2024 to over 215 million by 2028. Meanwhile, ACI World expects 10.2 billion travellers in 2026. These trends show a clear path: more travellers, more eSIM-ready devices, and more people open to using them. What is missing is clarity.

For travel eSIM providers, this changes what it takes to compete. It is not enough to just say eSIM is cheaper than roaming. Travellers need to feel confident. They want to know if their phone works with eSIM, how to activate it, what to expect when they arrive, and what help is available if something goes wrong.
The best brands will not just sell data. They will remove doubt.
This is important because eSIM changes how people travel. For years, travellers used physical SIM cards or roaming plans. Downloading a data plan before flying and connecting right away is still new for many. This makes the awareness gap a chance for brands to grow.
Companies that explain eSIM clearly can become trusted guides. They can make compatibility, setup, and everyday use simple, making eSIM a normal part of getting ready for a trip.
This matters even more as the market gets crowded. As more providers join, price and coverage will not set brands apart as much. Many companies will offer similar plans. But not every company will make things easy for travellers.
The next stage of competition will focus on simplicity, transparency, and support. Clear pricing, easy setup, reliable help, and practical advice will matter more than technical features.
This also means looking beyond just the sale. The customer journey starts before the trip, when travellers are planning and deciding what to set up ahead of time. Brands that help travellers at this stage can build trust early.
This could mean explaining when to install an eSIM, how to check if a phone is compatible, how to keep a main number active, or how much data different activities use. These details matter because travel often feels uncertain. People are not only buying data. They are buying peace of mind. That is the real chance behind the eSIM awareness gap.
The market does not need to convince travellers that staying connected is important. They already know that. What matters now is making eSIM feel simple, reliable, and easy to use. The next phase of growth will not come from technology alone. It will come from education, building confidence, and good experiences.
Brands that understand this will have an edge. They will not just sell data plans. They will help travellers feel ready before they leave and connected when they arrive.
In a market where millions already have the right device but still do not know what an eSIM is, this could be the biggest opportunity.
