Holafly vs AeroSims for Spain (2026): When Unlimited Isn’t the Smart Buy
Holafly vs AeroSims for Spain (2026): When Unlimited Isn’t the Smart Buy
Updated August 2026 · Prices verified on both providers’ product pages and subject to change
Madrid tapas crawls, Barcelona’s Gaudí queue, ferry Wi-Fi that never works on the way to Mallorca — Spain is Europe’s most-visited beach-and-city combo, and one of its cheapest places to buy travel data. Since AeroSims’ August 2026 reprice the unlimited race is decided by trip length — and whether you should buy an unlimited plan at all is still the better question.
The quick verdict
Pick AeroSims for unlimited trips up to two weeks: $21.90 vs Holafly’s $23.90 for a week, $15.90 vs $17.50 for 5 days, $30.90 vs $32.90 for 10 — with a price printed for every length from 1 to 90 days. At 15 days it’s $44.40 vs $44.50, a coin toss.
Pick Holafly for a 30-day unlimited stay: $64.50 vs $87.90 — a clear gap, printed in full below. For most Spain trips, though, the real answer is a fixed data package — 10 GB for $8.90, valid 30 days — with a 30-day money-back guarantee on eSIMs you haven’t installed yet either way.
EU resident? Your home plan already roams in Spain at no extra cost. You likely need nothing at all — that honesty costs us a sale and earns your bookmark.
| 7-day Spain | AeroSims | Holafly |
|---|---|---|
| Price (7 days, unlimited) | $21.90 | $23.90 |
| Fixed data packages | 3–50 GB from $3.90 | Not listed on its country page |
| Backup data after the plan ends | Not included | 1 GB/month (“Always On”) |
| High-speed allowance | Fair-use policy applies | Fair-use policy applies |
| Network | Orange · Movistar · 4G/5G | Local partner · 4G/5G |
| Hotspot / sharing | Included; counts toward the same daily allowance | 1 GB/day sharing (per Holafly’s site) |
| Refunds | 30 days, if the eSIM isn’t installed yet | Up to 6 months, conditions apply |
The price math, printed in full
Unlimited, like for like: Holafly charges $11.90 for 3 days, $17.50 for 5, $23.90 for 7, $32.90 for 10, $44.50 for 15 and $64.50 for 30. AeroSims now charges $10.90, $15.90, $21.90, $30.90, $44.40 and $87.90 at the same lengths — every row up to 15 days goes to AeroSims — the 15-day row by all of $0.10 — while the 30-day row goes clearly to Holafly, and pretending otherwise would insult your ability to read a table. Our page also carries a price for every length in between — a 4-day Madrid break is $13.63, an 8-day Andalusia loop $24.93. Holafly offers other durations through a calendar as well, but publishes prices only for the six lengths above, so those six are what the table compares.
Now the row Holafly doesn’t have: 10 GB for $8.90. Spain is one of AeroSims’ cheapest destinations per gigabyte, and a normal fortnight of maps, WhatsApp, photos and the odd reel fits comfortably in 10 GB. Unless you stream video daily over mobile data, the package beats both unlimited columns above — by well over half.
The option Holafly doesn’t have: fixed data packages
For Spain, Holafly sells unlimited only. AeroSims sells both lines (standard packages valid 30 days; the 50 GB size also comes as a 180-day version):
| Data (30 days) | AeroSims | Covers roughly |
|---|---|---|
| 3 GB | $3.90 | A city weekend |
| 5 GB | $4.90 | A light-use week |
| 10 GB | $8.90 | One to two normal weeks |
| 20 GB | $16.90 | Two heavy weeks |
Long-stayers — language courses, remote-work months, the Camino — should look at 50 GB valid 180 days for $44.90 before renting any monthly unlimited plan. Every size lives on one page: AeroSims Spain data packages — see where Spain sits in the eSIM Price Index 2026.
“Unlimited” fine print: what fair use really means
Every unlimited travel eSIM has a fair-use policy, set by the local network. The same applies to the AeroSims plan. After a daily high-speed allowance the connection continues at a reduced speed until the next day — maps and messaging keep working; streaming gets slow.
Holafly’s FAQ describes its fair-use rule as a temporary measure applied for no more than a day; the threshold isn’t published on the product page. Neither plan is infinite — which is exactly why a fixed package you fully control is often the calmer purchase.
Who needs nothing at all: the EU-roaming reality check
If you live in the EU or EEA, your home SIM roams in Spain — mainland, Balearics and Canaries — at domestic rates under roam-like-at-home rules. Buying any travel eSIM would be paying twice. This comparison is for visitors from the US, UK (check your plan — many now charge for EU roaming), Canada, Australia, Asia and everywhere else facing real roaming bills.
Coverage: cities, costas and the islands
The AeroSims Spain eSIM runs on Orange and Movistar with 4G everywhere tourists go and 5G in the big cities. Madrid, Barcelona, Seville, Valencia, Granada and the coastal strips are all solid, and the plan covers the Balearics (Mallorca, Menorca, Ibiza) and the Canary Islands the same as the mainland. Expect thinner signal only in the emptiest inland stretches and high Pyrenean valleys.
Spain eSIM questions travelers ask
Is AeroSims cheaper than Holafly for Spain?
at every length in Holafly’s published price table up to 15 days, yes ($21.90 vs $23.90 for a week; the 15-day row by $0.10). For a 30-day unlimited stay Holafly wins clearly ($64.50 vs $87.90) and offers a longer refund window. Fixed packages remain AeroSims-only: 10 GB for $8.90 is well under half of either unlimited plan’s weekly price.
Does the eSIM work in Mallorca, Ibiza and the Canary Islands?
Yes — the Balearics and Canaries are covered like the mainland, on the same networks.
What does the fair-use policy mean in practice?
A fair-use policy applies, set by the local network: after a daily high-speed allowance the connection continues at a reduced speed until the next day. Most travelers never come close to it on a normal day of maps, messaging and social.
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.
When does the plan start counting?
When the eSIM first connects to a Spanish network — not at purchase. Install it at home days before you fly and lose nothing. Packages count gigabytes, not days, within their validity window — 30 days for standard sizes, 180 days for the long-stay 50 GB.

Bottom line
Since the reprice, Spain’s unlimited race up to two weeks goes to AeroSims — and the month still goes to Holafly; we print both. But the sharper conclusion hasn’t changed: Spain data is so cheap you probably shouldn’t be in that war at all. 10 GB for $8.90 covers most trips, comes with a 30-day money-back guarantee on eSIMs you haven’t installed yet, and leaves enough saved for one more proper dinner in Sevilla.
