🇪🇺 Europe eSIM Comparison

Airalo vs AeroSims for Europe (2026): 10 GB for $19.90 vs $31 — and Every Plan Runs 30 Days

Updated July 2026 · Prices verified at the AeroSims checkout and Airalo's public Eurolink listings, subject to change

A Europe trip crosses more borders in two weeks than most trips do in a lifetime — Paris to the Alps, a Lisbon tram, island-hopping out of Athens. Buying data country by country is the one hassle you can delete before you fly, and both Airalo and AeroSims promise exactly that: one eSIM, one QR code, the whole continent. We compared them head-to-head so you can decide in two minutes.

The price gap, in real trips

Take the classic two-week, two-country trip — say Paris and Rome. Most travelers burn 1–2 GB a day on maps, WhatsApp, social and photo backups, so a 10 GB plan fits comfortably. That's $19.90 with AeroSims vs $31.00 with Airalo — about a third less for the identical bucket, both valid long enough that you don't have to think about dates.

Stretch it to a month-long, four-country rail loop and the gap widens in dollars: 20 GB costs $33.90 vs $48.00 — $14 stays in your pocket. And if your route stays inside the 35-country list, the budget version's 20 GB at $21.90 is 54% below Eurolink's price for the same gigabytes.

Honesty requires one footnote: at the very top the two meet. Airalo's 50 GB/30-day plan is $70.00 against AeroSims' $68.90 — effectively a tie. If 50 GB in a single month is your use case, price won't decide this matchup; validity flexibility and checkout preference will.

Coverage: 42 countries vs the list you actually need

Airalo's Eurolink covers 42 countries in one plan — genuinely broad, and if your itinerary includes edge cases beyond the usual EU-plus-UK circuit, that single list is a real convenience. AeroSims takes a different approach: instead of one plan priced for the maximum list, it sells several Europe versions so you only pay for the coverage you use. The 33- and 35-country versions start at $3.90 for 3 GB; the featured 30+ country plan runs 3–50 GB at the prices in the table above; and a 40+ country version exists for wider routes — its 10 GB is $26.90, still under Eurolink's $31.00 for the comparable list.

Whichever you pick, border-hopping is automatic: cross from France into Italy on the train and the eSIM reconnects to a local partner network on its own. No swaps, no settings, nothing to do at the border. Just check the country list on the product page against your itinerary before you buy — that's true for both providers, since neither list covers literally every European microstate and territory the same way.

The "unlimited" question — and the fine print both sides publish

Airalo built its name on fixed-GB plans, and in most single countries that's still all it sells. For Europe, though, Eurolink does include an Unlimited option: 3 GB per day at full speed, then throttled to 1 Mbps until the next day — $27.00 for 7 days, $71.00 for 30. To Airalo's credit, that daily cap is published right on the plan, which is more than some "unlimited" competitors manage.

AeroSims doesn't sell a Europe-wide unlimited — its regional plans are honest fixed buckets. Run the math before you assume that's a disadvantage: $71.00 buys Airalo's Unlimited month, while $68.90 buys 50 GB with no daily gate at all. Upload a day's worth of 4K video and burn 8 GB at full speed if you like; the Unlimited plan would have slowed to 1 Mbps after gigabyte three that day. If you genuinely stream heavily every single day, Airalo's unlimited math can win. For everyone else — and most travelers use 1–2 GB a day — the bucket is cheaper and never throttles.

Spending the whole trip in one country? AeroSims does sell unlimited there, with a bigger daily fair-use allowance: 5 GB per day at full 4G/5G speed, reduced afterwards until the day resets. Example: France unlimited for 7 days is $27.24 — the same money as Eurolink Unlimited's $27.00 week, but with a 5 GB daily high-speed allowance instead of 3 GB. One country instead of 42, more headroom every day. A fair-use ceiling exists on every unlimited plan either way — AeroSims' is simply set higher.

Do you even need a travel eSIM in Europe?

If you live in the EU, no — your home SIM already roams across member states at no extra cost. Everyone else should do the math. US carriers' international day passes commonly run around $10–12 per day, which makes a two-week trip cost $140+ for data you could have for $19.90. Many UK plans now charge again for EU roaming since Brexit. And the old backup — buying a local SIM on arrival — dies at the first border: a Spanish tourist SIM is little help in Portugal, and airport kiosk queues after a long-haul arrival are nobody's favorite part of Europe. An eSIM installed at home before you fly is working before you clear customs and keeps working across every border on your route.

Long stays: the six-month math

Both providers quietly serve the slow-travel and remote-work crowd with long-validity plans, and here the per-gigabyte gap persists. Airalo's biggest Eurolink pack is 100 GB for 180 days at $185.00 ($1.85/GB). AeroSims sells 50 GB for 180 days at $73.90 ($1.48/GB) — and if you need the full 100 GB, two of those come to $147.80, about 20% less than Airalo's single pack for the same data and the same six months. For a semester abroad or a nomad winter split between Lisbon, Tbilisi-bound layovers and the Alps, that difference buys a few very good dinners.

Europe eSIM questions travelers ask

Is AeroSims really cheaper than Airalo for Europe?

At like-for-like 30-day sizes, yes: 39% less at 5 GB ($11.90 vs $19.50), 36% less at 10 GB ($19.90 vs $31.00), 29% less at 20 GB ($33.90 vs $48.00). The one exception is 50 GB/30 days, where the two are $1.10 apart. Prices as of July 2026 at both providers' public listings.

Does one eSIM really keep working when I cross borders?

Yes. The eSIM reconnects automatically to a partner network in the next country — leave data roaming switched on for the eSIM line and do nothing else. Your data bucket is shared across all covered countries, not split per country.

Airalo has an Unlimited Eurolink — why doesn't AeroSims offer unlimited for Europe?

AeroSims keeps its regional Europe line as fixed buckets with no daily speed gate; Airalo's Unlimited is 3 GB/day at full speed, then 1 Mbps. At the month scale it's $68.90 for an ungated 50 GB vs $71.00 for the gated unlimited — pick by usage pattern, not by the word "unlimited." For single-country trips, AeroSims unlimited plans exist with a 5 GB/day full-speed fair-use allowance.

Do I need an app or account?

With AeroSims, no — the QR code arrives by email within seconds and installs from your phone's settings. Airalo purchases run through an account in its app or website; the app is genuinely well made and handy if you manage several eSIMs, but it's an extra step a one-trip traveler doesn't strictly need.

When do the 30 days start counting?

When the eSIM first connects to a supported European network — not at purchase. Install it at home days before you fly and lose nothing.

Does my WhatsApp number keep working?

Yes. The eSIM is data-only; your home SIM stays installed for calls and SMS codes, and WhatsApp keeps your existing number everywhere in Europe.

Which countries exactly are covered?

It depends on the version — AeroSims sells 33-, 35-, 30+- and 40+-country Europe plans, and Airalo's Eurolink lists 42. The full country list is on every product page; if your route includes less common stops, check them against the list before buying either brand.

Where can I compare eSIM prices more broadly?

See the eSIM Price Index 2026 — a 186-country study of what travel data actually costs per gigabyte, including why Europe is one of the world's cheapest regions to connect.

Bottom line

Same continent, same one-QR-for-every-border promise. Airalo's Eurolink is a polished product with the widest single list and a fairly disclosed unlimited option — it earns its reputation. But at the sizes most travelers actually buy, AeroSims charges about a third less for the same 30-day gigabytes, starts at $3.90 instead of $11.00 for an entry plan, and skips the account-and-app step entirely. For Europe in 2026, the rational pick is AeroSims; Airalo remains a fine premium fallback if its ecosystem is already home for you.
