Cheapest Europe Data eSIM in 2026: A Full Cost-Per-GB Breakdown

Why the Price Per Gigabyte Is the Only Number That Matters

You’ve already decided to skip the airport SIM kiosk. Smart move. But once you start comparing Europe eSIM providers, the marketing noise gets loud fast. “Best value.” “Top-rated.” “Most affordable.” Meanwhile, almost nobody shows you the one metric that cuts through all of it: cost per gigabyte.

This article keeps it clean. We looked at three providers that offer fixed-data 30-day plans—no unlimited throttled packages, no short-expiry tricks—and ran a straightforward cost-per-GB calculation at every tier. The result is a plain comparison that lets you decide where your money actually goes.

TL;DR — The Quick Verdict

For lighter users (under 20 GB), Nomad offers some of the sharpest per-GB rates on the market. Airalo is the most familiar name but costs noticeably more across every tier. For heavier users—anyone planning a longer stay, remote work, or heavy streaming—Europe Number eSIM offers outstanding value, with 30 GB, 60 GB, and 120 GB plans at prices that undercut Airalo significantly and include a French number for incoming calls at no extra charge.

How We Compared: The Ground Rules

30-day plans only. Seven-day and 15-day plans create false comparisons—a cheap weekly rate multiplied across a month rarely stays cheap. All plans in this article are valid for 30 days.

No unlimited plans. Any plan that throttles your speed after a daily cap is not unlimited—it is a capped plan with misleading marketing. We excluded all unlimited-branded products to keep the comparison honest.

Multi-country coverage. All plans cover the EU/EEA zone at minimum. Single-country plans were excluded.

Cost-per-GB formula: Total plan price divided by total usable gigabytes. Simple arithmetic, no adjustments.

Currency: Airalo and Nomad prices are in USD. Europe Number eSIM prices are listed in EUR as shown on site, with approximate USD equivalents noted at ~1.05 USD per EUR.

The Three Providers

Airalo

One of the best-known names in the eSIM space, Airalo offers a wide range of Europe plans. The EU+UK plan covers 33 countries including the UK, which is a practical advantage for anyone crossing the Channel. The app is polished, onboarding is straightforward, and the brand is well-established. The trade-off is price: Airalo consistently sits at the more expensive end of the market, especially as data volumes increase.

Nomad

Nomad has quietly become one of the most price-competitive options for fixed-data Europe plans. The platform is clean, coverage is solid across 35+ European countries, and the pricing is hard to argue with—particularly at the mid-to-large data tiers. Plans are straightforward fixed-data packages with no throttling, and the website is transparent about what you’re buying. No unlimited plans, no fair-use gotchas.

Europe Number eSIM

Europe Number eSIM is a Bouygues Telecom partner that takes a different approach from the other two: its plans are designed for travellers who need a serious amount of data and want a European number alongside it. Every plan includes a French number that activates for incoming calls—useful for OTP verification, local contacts, and online services that require a European phone number. Plans come in three tiers (30 GB, 60 GB, and 120 GB) and cover 39 European countries plus the UK for 30 days.

30-Day Plan Comparison: Airalo vs Nomad

For travellers who need somewhere between 5 GB and 20 GB over 30 days, the relevant contest is between Airalo and Nomad. Europe Number eSIM starts at 30 GB, so this tier sits outside its range. Here’s how the two compare:

Nomad wins this tier cleanly. At 10 GB, it undercuts Airalo by $10. At 20 GB, the gap widens to $17. For travellers who need straightforward data without a European number, Nomad is the harder value to beat at this range.

Where Europe Number eSIM Enters the Picture

Europe Number eSIM isn’t trying to compete with 5 GB weekend plans. Its catalogue starts at 30 GB and is aimed squarely at travellers who use a lot of data: digital nomads working remotely, extended visitors, content creators uploading on the road, or anyone who finds themselves hitting the top of a 20 GB plan before the month is out.

Here’s how the three tiers compare against Airalo at comparable data volumes:

Provider	Plan	Price	Validity	Cost per GB	French Number
Europe Number eSIM	30 GB	€30 (~$31.50)	30 days	~$1.05	✓ Included
Europe Number eSIM	60 GB	€40 (~$42.00)	30 days	~$0.70	✓ Included
Europe Number eSIM	120 GB	€48 (~$50.50)*	30 days	~$0.42	✓ Included
Airalo (EU+UK)	20 GB	$39.00	30 days	$1.95	✗
Airalo (EU+UK)	50 GB	$72.00	30 days	$1.44	✗

*Europe Number eSIM’s 120 GB plan is currently on sale from €60.00.

The comparison tells a clear story. Europe Number eSIM’s 30 GB plan at €30 (~$31.50) gives you more data than Airalo’s 20 GB plan at $39.00—50% more gigabytes for less money. At 60 GB, the gap widens further: €40 versus Airalo’s $72 for a comparable volume. The 120 GB plan at €48 on sale is, frankly, in a different category entirely at ~$0.42 per GB.

The French Number: Why It Changes the Calculation

Every Europe Number eSIM plan includes a French phone number for incoming calls. That might sound like a niche feature, but in practice it matters in several situations travellers regularly encounter: two-factor authentication and OTP codes from European services, booking confirmations that require a local number, Airbnb or rental agencies that call rather than email, and anyone working with European clients who expects to reach you on a phone.

Getting a standalone European number through a secondary app or service typically adds another €5–€15 per month. Europe Number eSIM bundles it into the data plan price—which means the already-competitive per-GB rate is covering more than just data.

What About Top-Ups?

If you underestimate your usage mid-trip, top-up flexibility matters. Airalo allows top-ups but often at a higher per-GB rate than the original plan. Nomad also supports additional data purchases. Europe Number eSIM’s tiered pricing means moving up to a larger plan is straightforward, and the consistent pricing structure means you’re not penalised for buying conservatively and adjusting.

For anyone unsure of their usage, the safest approach with any provider is to start with less than you think you need and top up rather than over-buy and waste allocation. All three providers on this list support that approach.

Network Quality: Does the Provider Actually Matter?

Less than the marketing would have you believe. All three providers route data through roaming agreements with Europe’s major carriers—Vodafone, Orange, Bouygues, T-Mobile, and similar tier-one networks. The towers you connect to are the same regardless of which eSIM brand you purchased. In practice, connection quality differences between providers are minimal for most travellers in urban and suburban areas.

Europe Number eSIM is a direct Bouygues Telecom partner, which means it operates on the same infrastructure as one of France’s three major carriers rather than reselling another reseller’s network access. For travellers spending significant time in France and neighbouring countries, that’s a meaningful transparency point.

Who Should Use Which Provider?

Short Trips, Light Usage (5–10 GB)

Nomad is the strongest value option in this range. At $18 for 10 GB over 30 days, there’s little to argue with. Airalo is a reasonable alternative if you’re already familiar with the app or value its wider country coverage.

Medium Trips, Moderate Usage (10–20 GB)

Nomad remains competitive here—$22 for 20 GB is hard to beat on a pure data basis. If you’re comfortable managing an eSIM without a dedicated app, Nomad is worth considering. Airalo costs more for the same allocation, though the app experience is more polished.

Extended Stays and Heavy Users (30 GB+)

This is where Europe Number eSIM pulls well ahead. At €30 for 30 GB and €40 for 60 GB, the cost-per-GB rate is significantly lower than anything Airalo offers at comparable volumes. Add the included French number, and the value proposition is strong for digital nomads, remote workers, long-stay visitors, and anyone who simply refuses to ration their data while travelling.

First-Time eSIM Users

Airalo has the most polished app-based onboarding experience and is a safe first choice if you’ve never set up an eSIM before. That said, all three providers deliver via QR code with clear setup instructions, and the process is the same three steps regardless of which brand you use.

The Bottom Line

For shorter European trips with moderate data needs, Nomad offers the best per-gigabyte value among fixed-data 30-day plans. Airalo is more expensive at every comparable tier but comes with a well-known brand and app.

For anyone who needs 30 GB or more—and particularly for those who’d benefit from a European phone number—Europe Number eSIM is the strongest option on the market. The 60 GB plan at €40 and the 120 GB plan at €48 deliver a cost per GB that no mainstream eSIM provider comes close to matching at that volume, and the bundled French number adds real-world utility that pure data plans simply don’t offer.

The maths are what they are. If you use a lot of data in Europe and you’re still paying Airalo prices, you’re overpaying by a significant margin.
