Know Your Europe eSIM: The 3 Types Every Traveller Should Understand

Not all Europe eSIMs are created equal

Search “Europe eSIM” and you’ll get hundreds of results — different providers, different price points, wildly different promises. But here’s what most comparison sites never tell you: underneath all that variety, there are really only three types of Europe eSIM. Once you know which type you actually need, the decision gets a lot simpler.

TL;DR: The three types are fixed data (Airalo), unlimited data (Holafly), and data with a temporary European phone number (Europe Number). Types one and two give you internet access only. Type three gives you internet plus a real local number — one you can call and text from, useful for bookings, hotels, car hire, and staying reachable without relying entirely on WhatsApp.

Type 1: Fixed data eSIMs

Fixed data eSIMs give you a set amount of mobile data — 5GB, 10GB, or 20GB — to use across your trip. Airalo is the best-known provider in this category, with Europe plans covering most of the continent at competitive per-GB rates.

These plans work well for light travellers: people who mostly rely on Wi-Fi and just need mobile data as a backup for maps, messaging apps, and occasional browsing. Once you hit your limit, you top up or switch to Wi-Fi until you find a connection.

The limitation is straightforward — you’re working with a fixed ceiling. If you’re streaming, navigating heavily, or working remotely for any stretch, a 10GB plan can vanish fast. And like all standard eSIMs, a fixed data plan gives you internet only. No local phone number. No ability to call or receive calls from European numbers. If you’re looking for a europe esim with number, this type won’t cover it.

Type 2: Unlimited data eSIMs

Unlimited data eSIMs remove the data cap entirely. Holafly popularised this category for European travel, and it’s a genuinely useful option for heavier users — digital nomads, remote workers, or anyone on an extended trip who can’t risk running out of data mid-journey.

The catch, which Holafly and similar providers disclose in their terms, is that unlimited doesn’t always mean full-speed. Most plans throttle after a daily or weekly threshold — still usable for everyday tasks, but not ideal for uploading video or hosting video calls consistently. According to GSMA’s eSIM guidelines, speeds on tourist-grade data plans are typically subject to fair-use policies regardless of how they’re marketed.

Like fixed data plans, unlimited eSIMs are data-only. There’s no phone number attached. You can use WhatsApp or FaceTime for internet-based calls, but you can’t make or receive traditional calls, can’t receive SMS from services that require a local number, and can’t be reached by someone who only has a regular number for you. For many travellers that’s fine. For others — especially those travelling for work or on longer stays — it becomes a genuine gap.

Type 3: Data eSIMs with a European phone number

This is where Europe Number fits. A europe esim with number gives you both mobile data and a real, temporary European phone number — one you can make calls from, send and receive SMS with, and share with hotels, rental agencies, restaurants, or anyone who needs to reach you locally.

It’s the type of eSIM most travellers don’t know exists until they need it. Booking a table in Paris? The restaurant prefers a French number. Renting a car in Spain? The agency will text your booking reference to a local number. Staying in Rome for a week and expecting calls from locals? You need a number they can actually dial.

Europe Number offers this as a combined plan — data bundled with a temporary European number, activated before you board and ready the moment you land. The number is real: it works like any other local SIM for incoming and outgoing calls and texts. Think of it as the full-stack travel SIM rather than an internet-only workaround.

If you’re weighing your options, an europe esim with a number attached is the closest experience to using your home SIM abroad — without the roaming charges.

Which type do you actually need?

The honest answer depends on your trip. Here’s a simple way to think about it.

If you’re a light user who mostly relies on Wi-Fi and just needs occasional mobile data for maps and messaging, a fixed data plan from a provider like Airalo is the most cost-effective route. Buy the right size, use it sensibly, and you’re done.

If you use data heavily — streaming, remote work, a long itinerary across multiple countries — an unlimited plan like Holafly’s removes the anxiety of watching your data bar fall. Just check the fair-use policy before you buy.

If you’re travelling for business, meeting local contacts, renting accommodation, or staying for more than a week, an europe esim with a local number is the upgrade that pays for itself the first time someone needs to call you. It’s not just about being able to make calls — it’s about being fully reachable.

What about device compatibility?

All three types require an eSIM-compatible device. Most flagship smartphones released since 2018 support eSIM — including iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. If you’re unsure, check your device settings under Mobile / Cellular or visit your manufacturer’s support page.

One exception: some devices sold in mainland China lack eSIM support regardless of the model number. Always verify before purchasing a plan.

How setup works

Setup is the same across all three types. Once you purchase, you’ll receive a QR code — by email or inside the provider’s app. Go to Settings > Mobile / Cellular > Add eSIM, scan the code, and follow the on-screen steps. The whole process takes under five minutes and can be done before you leave home.

With Europe Number’s plans, your temporary European number is issued at the same time. Save it somewhere easy to share — you’ll want to hand it over to contacts, rental companies, and accommodation before you travel.

Most eSIMs activate on first use, so there’s nothing to do at the airport. Land, turn off airplane mode, and you’re connected.

The bottom line

The Europe eSIM market has grown quickly, and the options can feel overwhelming. But once you know the three types — fixed data, unlimited data, and data with a number — the decision becomes much easier.

Data-only plans serve a purpose and are well-priced for what they offer. But if you want to travel without the communication gaps that come with an internet-only SIM, a plan that includes a real European number is the smarter choice. Europe Number was built specifically for that use case — and it’s the one type the other comparison sites tend to skip over.

Frequently Asked Questions

What are the three types of Europe eSIM?

The three types are fixed data eSIMs (like Airalo), unlimited data eSIMs (like Holafly), and data eSIMs with a European phone number (like Europe Number). Fixed data gives you a set allowance; unlimited removes the data cap; data with a number adds real calling and SMS capability on a local European number.

Can I make calls with a Europe eSIM?

It depends on the type. Fixed data and unlimited data eSIMs are data-only — no local number, no traditional calls or SMS. Europe eSIMs with a number include a real temporary European number you can use to make and receive calls and texts, just like a local SIM.

Is Airalo data-only for Europe?

Yes. Airalo’s Europe plans provide fixed data with no local phone number. You can use internet-based apps like WhatsApp or FaceTime for calls, but you can’t make or receive traditional calls or SMS via a local European number.

Does Holafly include a phone number?

No. Holafly’s Europe plans are unlimited data only — great for heavy users, but there’s no local European number included. If you need to make or receive calls on a real local number, you’ll need a different type of plan.

What is a Europe eSIM with number?

It’s a plan that gives you both mobile data and a real temporary European phone number — the type offered by Europe Number. You can call, receive calls, text, and browse from the same eSIM, making it the most complete option for travellers who need more than just internet access.

Which Europe eSIM type is best for longer stays?

For stays longer than a week — especially work trips or anywhere you expect local calls or SMS — a data eSIM with a European number is the most practical choice. It means you’re fully reachable by anyone, not just contacts who already have you on WhatsApp.
