Internet Abroad: eSIM, Local SIM or Roaming? Which Option Is Actually Worth It?
Short summary. For most trips to Europe, a travel eSIM is the easiest way to get mobile data abroad. You install it before you leave and switch it on when you land. A local SIM card is usually cheaper if you stay in one country for a few weeks. Roaming on your home plan is the most convenient but often the most expensive. Below I explain what I tried, what it cost me and which one I choose now. – Last updated October 2026

What is an eSIM?
An eSIM is a digital SIM built into your phone. Instead of putting a plastic card in a tray, you scan a QR code or use an app and your phone adds a mobile plan. You can keep your home number active on the physical SIM and use the eSIM only for data while you travel. That is why a travel eSIM is popular for short trips.
eSIM vs SIM card, quick comparison
| Travel eSIM | Local SIM card | Home carrier roaming | |
|---|---|---|---|
| Setup | Before you travel, from your phone | At the airport or in a shop after landing | Already active, sometimes needs a package |
| Your home number | Stays active on the other line | Usually replaced while the local SIM is in | Stays active |
| Best for | Short trips, several countries | One country, longer stays | Very short trips, emergencies |
| Cost | Mid, fixed before you travel | Often lowest per GB | Often highest |
| Main risk | Phone must support eSIM and be unlocked | Queues, ID checks, store hours | Surprise charges without a package |
Prices change often, so check the current rate before you buy.
I work remotely. Which means when I travel, my work doesn’t stop. Emails keep coming in, files need to be uploaded, meetings still happen. That’s why unlimited internet plans are not a luxury for me while traveling; they’re a necessity.
Over time, this lifestyle has taught me a lot about internet in Europe for tourists and digital nomads alike. On top of that, I love spontaneous travel. I don’t like planning every detail weeks in advance. I plan the basics, of course, but if I discover a place I love or want to change my route, I want that flexibility.
That kind of freedom means constantly checking maps, researching the next destination, booking accommodation last minute, or buying tickets on the go. Long story short: reliable internet, preferably unlimited, is essential for me.
Which Internet Option Should You Choose Abroad?
There are a few main ways to stay connected while traveling internationally. I’ve tried all of them, and now I have a clear idea of what works best in different situations.
Before choosing between local SIM cards, roaming, or eSIMs, the most important question to ask yourself is: How much internet do you actually need?
If you’re working online, managing bookings on the go, or relying heavily on maps and navigation, limited data plans can become frustrating very quickly. This is where unlimited internet plans really make a difference.
Buying a Local SIM Card in the Country You Visit
If you’re staying in one country for a longer period and need local calls as well as data, buying a physical SIM card can make sense.
However, getting a SIM card isn’t always straightforward. In some countries, you may need to show ID, fill out paperwork, or wait for the SIM card to be delivered. So it’s best to research this in advance rather than assuming you’ll easily buy one upon arrival.
For travelers who are comfortable using public Wi-Fi and don’t need constant connectivity, a local SIM combined with Wi-Fi can work. But for those looking for internet in Europe for tourists who move frequently between countries, this option can feel limiting.
The prices I noted in December 2025 were around 5 euros for 1 GB and around 25 euros for 15 GB with Lebara. Check Lebara’s current rates before you rely on these numbers.
A local SIM makes sense when you stay in one country for a few weeks and want the best price per GB. It is less practical when you cross borders every few days, because you would need a new card for each country. In the EU, many plans also work across member states under EU roaming rules, but fair use limits can apply, so read the plan details.
Using Your Home Carrier’s International Roaming Plan
International roaming plans from your home carrier are usually the easiest option. You turn on your phone, and it works instantly. In December 2025 my Turkish carrier’s roaming package worked out to around 7 euros per day. Check your own carrier’s current rates, because roaming prices and rules differ a lot by country and plan.
That convenience comes at a cost. Roaming plans are often expensive, and most of them don’t offer unlimited data. If you’re traveling for just a day or two, this might be fine. But for longer trips, especially across multiple countries, roaming rarely compares to modern unlimited internet plans. Before you travel, check three things on your carrier’s website. First, which countries the package covers. Second, how many days or GB it includes. Third, how to turn it off so you do not pay extra after the package ends.
Finding the best eSIM for Europe: My Choice eSIM with Unlimited Data
For me, the most practical solution has been using an eSIM. During a long stay in the Netherlands, I initially relied on Wi-Fi and later switched to a physical SIM card. While it worked, my data usage increased quickly when I used my phone as a hotspot for work. I ended up paying significantly more than expected each month.
That’s when I decided to switch to an eSIM.
After trying several providers, I’ve been using Holafly for the past two years. It stands out because it offers eSIM Europe unlimited data, which makes traveling and working much more comfortable. You simply choose your destination and dates, and you’re connected with unlimited internet for the entire trip.
For anyone searching for the best eSIM for Europe, unlimited data is a huge advantage especially if you’re crossing borders frequently or working remotely.
In December 2025 a 4-day trip cost me around 3.5 euros per day with Holafly, compared with around 7 euros per day on my home carrier. Check the current price for your destination here: Holafly eSIM for Europe, 5% off with my link (affiliate link)
A note on “unlimited.” Unlimited eSIM plans sometimes come with a fair use policy. If you stream a lot or work online all day, read the terms and the hotspot rules before you buy. If you only need maps, messages and the occasional video call, a fixed GB plan is often cheaper.
Does my phone support eSIM?
Most recent phones do. As a rough guide, iPhones from the XS and XR generation onward support eSIM, many Samsung Galaxy phones from the S20 series onward do, and Google Pixel phones from the Pixel 3 onward do. Support also depends on your region, carrier and model, and some phones sold in certain countries only have a physical SIM tray. The quickest check is on your phone.
- iPhone: Settings, General, About, then look for “Digital SIM” or an EID number.
- Android: Settings, About phone, then look for an EID number, or dial *#06# and see whether an EID is shown.
Your phone also needs to be carrier-unlocked. If your plan is still tied to your carrier, ask them to unlock it before you buy an eSIM.
How to set up an eSIM abroad?
- Check that your phone supports eSIM and is unlocked.
- Buy a plan for your destination and open the confirmation email or the provider’s app.
- Connect to Wi-Fi and scan the QR code, or enter the activation details manually.
- Name the new line something clear, such as “Travel.”
- Choose the eSIM for mobile data and turn on data roaming for that line.
- Keep the eSIM installed before you fly, and switch it on when you land, as the provider instructs.
Install it at home while you still have reliable Wi-Fi. Some plans start counting days at installation or on first connection, so read the activation rule before you scan.
Wi-Fi Exists, But It’s Not Always Enough
Yes, Wi-Fi is widely available across Europe. Cafés, trains, hotels; most places offer it. But public networks are often unstable and not ideal for sensitive tasks.
When working, especially during video calls or while handling payments, relying on public Wi-Fi isn’t always the safest option. That’s why I prefer using my phone as a hotspot.
With eSIM Europe unlimited data, it doesn’t really matter where I am — on a train, in a park, or at a café. Work continues without interruptions. That said, if you don’t rely heavily on the internet while traveling, you can absolutely get by using Wi-Fi only.
Small Comforts That Matter on Long Trips
Unlimited internet also brings small comforts that make travel more enjoyable. On long road trips across Europe, we streamed shows, listened to podcasts, and made endless drives feel shorter.
These small details may not seem essential at first, but they really improve the overall travel experience — especially when you’re on the road for weeks at a time.
Comparing Internet Options in Europe
For those who like numbers, here’s a quick comparison.
Local SIM cards in countries like the Netherlands offer plans around €5 for 1 GB or €25 for 15 GB per month. These can work for light users but are often limiting for travelers.
With Holafly, a four-day trip costs around €3.5 per day with unlimited data. In comparison, international roaming from a home carrier (Turkish one) often costs around €7 per day and the data is usually limited.
For travelers looking for internet in Europe for tourists that works across borders, Holafly’s eSIM supports over 200 destinations and includes a built-in VPN, easy installation, and 24/7 customer support.

Frequently Asked Questions
What is an eSIM?
An eSIM is a digital SIM that you add to your phone with a QR code or an app, with no plastic card. You can use it for mobile data while keeping your home number active on your normal SIM.
What is the best eSIM for Europe?
It depends on how long you stay, how many countries you visit and how much data you use. I use Holafly and describe my experience above, but compare plans for your own dates and check the current prices.
Is an eSIM better than a local SIM card?
For short trips and multi-country routes, an eSIM is usually easier. For a few weeks in one country, a local SIM is often cheaper per GB. Choose by trip length and number of countries.
Does my phone support eSIM?
Many recent iPhones, Samsung Galaxy and Google Pixel phones do. Check your phone’s settings for an EID number and make sure the phone is carrier-unlocked.
Can I get unlimited data abroad?
Some eSIM plans are marketed as unlimited, but they often have a fair use policy that can slow your speed after heavy use, and hotspot sharing may be limited. Read the plan terms before you buy.
Can I keep my home number with an eSIM?
Yes, in most cases. Keep your home SIM active for calls and texts, and use the eSIM only for mobile data.
How do I install an eSIM?
Scan the QR code from your provider or enter the activation details manually in your phone settings. Do it on Wi-Fi, then select the eSIM for mobile data when you travel.
Final thoughts
If your trip is short or covers several countries, a travel eSIM is the simplest option. If you stay in one country for weeks, a local SIM can save money. Roaming is fine for emergencies and very short trips if you know the package rules. Whatever you pick, check the current price and your phone’s compatibility before you leave.
