Not sure how to pick a Europe data SIM? Getting online in Europe is a top concern for most travellers, and this article focuses on data SIM cards and eSIM services, so you don't need to worry about your options — almost every traveller's main needs can be met by finding the right Europe data plan on DJB.

Why does searching for Europe data products feel so overwhelming? Search "Europe internet" on Google and you still have to carefully compare which countries each card covers. Does it work in Switzerland? Can I use it during a layover in Turkey? Does a pan-Europe plan cover every country on my itinerary? Are famous destinations like Monaco, Vatican City, and San Marino included? Does it come with a phone number for calls? Is it truly unlimited, and how do you pick the number of days? If any of this sounds like your headache, don't worry — we're here to answer it all!

We won't dwell on international carrier roaming here, mainly because roaming plans for Europe tend to be far more expensive — even if you absolutely need to receive calls from your Taiwan number, most people still end up buying a separate Europe SIM card as their main data option.

In this post-pandemic era, longer trips to Europe and the US have become much more common, with everyone wanting to make the most of a single trip by staying longer. That's exactly when a good data plan matters most — ideally one you can start using the moment you land, with no fiddly extra registration steps.

Since a pocket router is less convenient to carry than a SIM card and also requires an extra power bank, many travellers find it inconvenient. Roaming on your home number is also comparatively expensive, so in recent years more and more people have switched to data SIM products, and with many new phones over the last couple of years supporting eSIM, it's become even more convenient. This article focuses on Europe data SIM cards and eSIM, how to choose the right product and plan for you, and what to consider if you need a phone number — making your choice of Europe data SIM that much easier!

Europe's major carriers

Carriers vary by country across Europe, but nearly every region has 2–3 major providers. Across DJB's four types of Europe data SIM — whether "Euro Travel SIM," "Euro Super SIM," "Euro Fun SIM," or "Euro In SIM" — we partner directly with local carriers in each region, and regularly update our carrier partnerships to give users the best possible network experience!

Europe data SIM — DJB's pick

DJB Euro Super SIM

Buy now

When it comes to the best-value Europe data SIM, the "Euro Super SIM" absolutely deserves a mention — before the end of August, it offers an upgraded high-data plan, with options for 40GB, 80GB, or genuinely unlimited data. It's the ideal SIM for travellers heading abroad, since most people need a generous data allowance, making it an outstanding value pick. One thing to note: the Euro Super SIM does not cover Switzerland or Turkey — if you're heading to either of these, please choose one of our other three Europe SIM options instead. DJB's Europe data SIMs are all plug-and-play by default — just remember to specify your intended local activation date, and the carrier will activate the SIM on that date accordingly, so you can swap it in and start using data the moment you land, with no need to worry about feeling lost in an unfamiliar place. The Euro Super SIM is also DJB's best-selling Europe SIM by repeat purchases, performing consistently well across Europe, and travellers who've used it rave about it every time!

  • 40GB, 80GB, or genuinely unlimited data (subject to fair usage policy)
  • Fixed 30-day validity — buy an additional card if you need more time

FAQ on getting online in Europe

-- Can DJB's Europe data SIM make phone calls?
Only the fixed-data plan under the Euro Super SIM includes voice calling — all others are pure data SIMs, with no calling function or phone number, so you'll want to use apps like Skype, LINE, or Facebook Messenger for calls instead.

-- Will swapping in a new SIM card affect the data already on my phone?

Swapping SIM cards won't affect your existing LINE, Facebook, or other app content and data, unless you're using an older-style phone that stores certain data directly on the SIM card — no need to worry otherwise.

-- Can someone who isn't tech-savvy use this?

Absolutely. DJB's global data SIMs are plug-and-play by default, and based on our experience serving hundreds of thousands of customers, roughly 95% of phones connect and configure automatically once the SIM is inserted. For the rest, simply follow the steps included in the packaging to check your connection and get online.

-- Is "unlimited" advertised online really unlimited with no throttling?

When shopping for a data SIM, if the listing mentions a "fair usage policy," that means the carrier restricts heavy users, and you may notice slower speeds or lose connectivity. So any card marked with this policy will be throttled at some point, regardless of whether it's advertised as "no throttling" — and DJB's Europe data SIMs are also subject to this policy.

-- Is free Wi-Fi available in Europe?

Yes, many restaurants and public spaces in popular European tourist spots offer free Wi-Fi hotspots, but we still recommend bringing your own reliable data connection, since travelling around Europe usually involves constant movement between cities and countries — it's far more reassuring to have your own data plan sorted before you go.
