In short: The real change behind eSIMs isn't "this month's news," but an underlying trend: Counterpoint Research predicts that close to 70% of mobile phones sold in 2030 will already be eSIM or iSIM ready, and Juniper Research estimates that the travel eSIM market will grow from approximately $1.8 billion in 2025 to over $8.7 billion in 2030.
eSIM is moving from a rarity to the standard
For years, the eSIM was "that rare option" hidden in mobile settings, something only used by early adopters or people who tinkered a lot with their phones. That is changing, and not because of a fad: it's a fundamental manufacturing trend.
According to Counterpoint Research forecasts, close to 70% of smartphones shipped in 2030 will already come with eSIM or iSIM capability ex-factory. It's not that the physical SIM will disappear overnight — it's still the majority in many markets today — but the direction is clear: more and more manufacturers are including it as standard, not as an extra.
For the user, this translates into something very specific: if you buy a new mobile phone in a few years, it will be normal for it to have an eSIM ready to use, just as it is normal today for it to have a fingerprint reader or wireless charging. If you want to better understand what exactly this technology is and how it differs from the traditional physical card, we explain it calmly in what is an eSIM.
Why manufacturers are betting on eSIM
That 70% of mobile phones sold in 2030 will have eSIM or iSIM ex-factory, according to Counterpoint Research, is not a coincidence or a passing fad of a couple of brands. There are quite practical reasons behind this industry bet.
On the one hand, removing the physical SIM card slot frees up internal space in the mobile; that tiny hole previously occupied by the card reader can be used for a battery, a larger camera, or simply to make the device more compact and more resistant to water and dust, as it does not need a tray to open from the outside. On the other hand, remote profile management is much more convenient for both the manufacturer and the operator: activating, changing, or deleting a line is done by software, without relying on the user having a tool at hand to eject the tray or sending a physical card by mail.
There is also a not insignificant security component: an eSIM cannot be physically extracted from the terminal, which reduces certain risks associated with mobile theft or fraudulent card swapping (the well-known "SIM swapping"), although of course it does not eliminate other digital risks. And for frequent travelers, the advantage is clear: no more the ritual of removing the local SIM with the tip of a paperclip while queuing at the airport.
Why demand for travel eSIMs is growing so much
The second piece of data is even more revealing of where the specific market we are interested in is going: that of the travel eSIM. Juniper Research estimates that this market grew from approximately $1.8 billion in 2025 and will exceed $8.7 billion in 2030. We are talking about multiplying the market size by more than four in five years.
What's behind such growth? Several things combine, and none is a mystery: there are more and more compatible mobile phones (Counterpoint's data above), more and more people have heard of eSIM and are losing their fear of using it, and international tourism continues to recover volume after the hardest years of the pandemic. Added to this is a real change in habits: today's traveler wants to have active data from the moment they land, without having to find a kiosk selling physical SIMs at the airport or paying their usual operator's roaming charges outside the EU.
If you are still debating between activating your company's roaming or using a separate eSIM, it's worth reading the comparison in eSIM vs roaming, because the differences in use are greater than they appear at first glance.

What has really changed for travelers
Less reliance on physical cards
The more mobile phones come with eSIMs as standard, the less sense it makes to carry a spare physical SIM in your suitcase, or to waste half an hour of your first day of vacation looking for a store that sells you a local card. An eSIM is installed before leaving home, with Wi-Fi, and usually takes a couple of minutes. If you have never installed one, we will show you step by step in how to install an eSIM.
Roaming in the European Union: what you already knew, but it's worth remembering
Within the EU, the regulation on roaming without surcharges (known as "Roam Like At Home"), in force since 2017, remains in effect. It allows residents of the 27 EU countries to use their usual data plan when traveling to another member country without paying extra for it. This does not change the fact that, outside the EU, roaming with your Spanish operator can still be expensive, and that is where a travel eSIM usually pays off more. If you are interested in the context of how Spaniards' roaming expenses abroad behave, you can consult it in statistics on roaming of Spaniards abroad.
More competition, more options
As the market grows—remember, according to Juniper Research, multiplying by more than four until 2030—more providers enter and more different plans appear: by days, by gigabytes, by region, with unlimited data or with adjusted bonuses for short trips. That's good for the traveler because there's more to choose from, but it also forces careful comparison instead of picking the first result that appears in the search engine.
The digital traveler also drives the trend
Another factor that helps explain this growth, although it is harder to measure with a single figure, is the change in the way people travel. More and more people are working remotely from another country for weeks, taking weekend getaways more frequently than before, or simply taking for granted that they will need a stable connection from minute one to move around with their phone, pay, book, or make video calls. This type of traveler is not content with "I'll find Wi-Fi when I get there": they want data now, and eSIM fits perfectly with this way of moving around the world.
Added to this is that comparing prices and coverage is much easier today than a few years ago, which also pushes up the number of people who decide to try a travel eSIM instead of settling for what their lifelong operator offers. If you have never been clear about the difference between classic roaming, a local chip, or an eSIM, it is advisable to first clarify the basic concepts: we review it in what is data roaming.
What this means for your next trip
All this market evolution is all well and good on paper, but what really matters is how it affects you when you're packing your bags. Here are some concrete things you can do with this information:
- Check your phone's compatibility before buying anything. Not all models, even within the same brand, have an eSIM. It's a minute of checking that saves you disappointment.
- Activate the eSIM before leaving home, with Wi-Fi. This way, you arrive at your destination with data already ready, instead of relying on airport Wi-Fi to install anything.
- Compare by real gigabytes and speed, not just by the price you see first. A cheaper plan with less data or reduced speed after exhausting the bonus can end up being worse.
- Have a backup plan for support. If something goes wrong at eleven at night in another country, you want to be able to write via WhatsApp and get a response, not just rely on an email that takes days.
- Don't assume that "eSIM" always means "cheap." The market is growing and there's more competition, but plans vary greatly depending on the destination and duration, so it's still worth comparing before buying.
At PuraSIM, for example, coverage extends to over 200 destinations, with real 4G/5G data plans and 24/7 support via email and WhatsApp, so if you have a question mid-trip, someone is there to help. You can view available plans for Europe or check specific options like the eSIM for Spain if you need data right here, for instance, for a family member or a second device.
You don't even have to be a frequent traveler to notice the difference. If you only travel once a year, the advantage of an eSIM is still the same: you avoid having to search for a phone store as soon as you land, you don't depend on the hotel's Wi-Fi working well for those important first tasks (location, transport, reservations), and you keep your usual number available in case someone needs to reach you by call or SMS while you use the eSIM's data for everything else.
How to choose your travel eSIM wisely
With a market growing so fast, it's good to have a small mental checklist before deciding:
- Destination and duration of the trip: a weekend in a European capital is not the same as a month touring several countries.
- Amount of data you usually consume: if you work remotely or upload a lot of content, you'll need more gigabytes than someone who only uses their mobile for maps and messaging.
- Real network speed: check if the plan offers real 4G/5G or if the speed is reduced after exceeding a certain consumption.
- Available support: it's better if you can contact via chat or WhatsApp in case of problems, not just via forms.
- Confirmed compatibility: check your mobile model before paying, not after.
And if you want to stretch the data you already have contracted instead of buying extra "just in case," we offer some practical tips on how to save data with your travel eSIM.
In conclusion
You don't need to invent catchy headlines every month to see where eSIM is headed: the underlying data already makes it quite clear. More and more phones are coming prepared for it, and the travel eSIM market is poised to multiply in the coming years according to industry estimates. For you, as a traveler, this translates into more options, more competition among providers, and, above all, an increasingly simple way to arrive at your destination with data ready from the first minute.
Frequently asked questions
What exactly is an eSIM and how does it differ from a physical SIM?
It is a SIM card integrated into the mobile itself, in digital format, which is activated by scanning a QR code or installing a profile, without the need to insert or change any physical card.
Do all mobile phones have an eSIM?
No, it depends on the model and brand. Today, mobile phones with eSIM, with physical SIM, and with both options coexist, although the manufacturing trend indicates that eSIM/iSIM compatibility will become increasingly common in the coming years.
Is an eSIM more expensive than my usual operator's roaming?
It depends on the destination and your operator's plan. Within the EU, roaming without surcharges usually covers normal use well; outside the EU, a travel eSIM is usually more cost-effective than activating your Spanish company's international roaming, especially on long trips or if you consume a lot of data, although it is always advisable to compare your specific rate before deciding.
Do I need Wi-Fi to activate an eSIM?
Yes, it is usually installed with a Wi-Fi connection before traveling, so you arrive at your destination with data already active and ready to use.
What happens if I run out of data in the middle of my trip?
You can usually purchase an additional plan or extend your current one from the same app or provider account, without having to reinstall anything from scratch.
Does eSIM work the same inside and outside the European Union?
Within the EU, they benefit from the surcharge-free roaming regulation in force since 2017, which allows you to use your usual Spanish operator plan in any of the 27 member countries without additional cost. Outside the EU, this regulation no longer applies, and each travel eSIM plan covers specific countries or regions, so it is advisable to check the coverage carefully before purchasing.
Can I use the eSIM and my regular line at the same time?
Yes, most mobile phones with eSIM allow you to have your usual physical line and the eSIM profile active at the same time, so you can continue to receive calls on your number while using the eSIM's data for everything else.
