Airalo vs AeroSims for Greece (2026): The Island-Hopper’s Price Math
Airalo vs AeroSims for Greece (2026): The Island-Hopper’s Price Math
Updated August 2026 · Prices verified on both providers’ product pages and subject to change
Ferry timetables that change hourly, a sunset photo queue in Oia, tavernas found on Maps five minutes before closing — Greece is a trip you navigate on your phone. Airalo practically invented the travel eSIM store; AeroSims is the specialist that sells Greek data at prices that look like typos. We put both product pages side by side in August 2026 so you can decide in two minutes.
The quick verdict
Pick AeroSims for fixed data — it isn’t close. 10 GB valid 30 days costs $8.90 against Airalo’s $20.00; 5 GB is $4.90 against $12.00. That’s half price or better at every size travelers actually buy.
Pick Airalo if you want unlimited at a standard length: its sticker prices win there ($27.00 vs $28.31 for a week, $69.00 vs $91.63 for 30 days), with its fair-use terms published on the plan card. We’d rather print that than pretend otherwise.
Odd trip lengths favor AeroSims even on unlimited: an 8-day island loop is $32.01 here versus buying Airalo’s 10-day plan at $34.00 — you pay for exactly the days you’re in Greece, any 1 to 90.
| Greece head-to-head | AeroSims | Airalo |
|---|---|---|
| 10 GB / 30 days | $8.90 | $20.00 |
| Unlimited, 7 days | $28.31 | $27.00 |
| High-speed allowance | Fair-use policy applies | 3 GB/day, then 1 Mbps (published) |
| Trip lengths (unlimited) | Any 1–90 days | 6 fixed plans (3–30 days) |
| Network | Wind · Vodafone · 4G/5G | Nova · Vodafone (per Airalo) |
| App required | No — QR by email | Account required · app-centric |
| Refunds | 30 days, if the eSIM isn’t installed yet | See provider terms |
Fixed-GB face-off: where the gap lives
Fixed packages are Airalo’s home turf — its Greek line starts at $4.00 for 1 GB over 3 days. But line the catalogs up at the sizes travelers actually buy, all with 30-day validity, and the gap is stark (as of August 2026):
| Data (30 days) | AeroSims | Airalo | You save |
|---|---|---|---|
| 5 GB | $4.90 | $12.00 | 59% |
| 10 GB | $8.90 | $20.00 | 56% |
| 20 GB | $16.90 | $35.50 | 52% |
| 50 GB | $42.90 | $42.00 | Airalo wins this row by $0.90 |
Yes, we printed the row we lose — that’s the deal on this blog. Long-stayers flip it back decisively though: AeroSims sells 50 GB valid 180 days for $44.90, while Airalo’s Greece plans max out at 30-day validity in its current catalog.

Unlimited: Airalo’s sticker price vs exact days
On unlimited, Airalo wins the standard lengths for Greece: $11.50/3 days, $19.00/5, $27.00/7, $34.00/10, $48.00/15 and $69.00/30, against AeroSims’ $12.65, $20.65, $28.31, $39.15, $55.50 and $91.63. To Airalo’s credit, its fair-use terms are printed on the plan card: full speed for 3 GB per day, then 1 Mbps until the daily reset. A fair-use policy applies to the AeroSims plan too — neither is infinite, and the honest question is whether your usage would ever notice.
Where AeroSims claws back on unlimited is the calendar: real island loops rarely last exactly 7 or 10 days. An 8-day Cyclades run costs $32.01 here versus $34.00 for Airalo’s 10-day plan; 12 days is $45.95 versus $48.00 for its 15-day plan. And if 10 GB covers you anyway — it covers most people — the whole unlimited question dissolves into that $8.90 package.
Who needs nothing at all: the EU-roaming reality check
If you live in the EU or EEA, your home SIM already roams in Greece at domestic rates — islands included. 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 and Asia, who face real roaming bills in Greece.
Coverage: Athens to the smallest ferry stop
The AeroSims Greece eSIM runs on Wind and Vodafone with 4G everywhere tourists go and 5G in the cities; Airalo’s plans list Nova and Vodafone. Athens, Thessaloniki, Santorini, Mykonos, Crete, Rhodes and Corfu are solid on either — Greek networks have covered the islands for decades because Greeks live there year-round. Expect thinner signal only on remote hiking stretches and mid-crossing on longer ferry legs; it returns as the next island approaches.
Greece eSIM questions travelers ask
Is AeroSims really cheaper than Airalo for Greece?
For fixed data, yes — roughly half price at 5, 10 and 20 GB (10 GB: $8.90 vs $20.00). For unlimited at standard lengths, Airalo’s sticker price is lower; AeroSims wins in-between durations (8 days: $32.01 vs $34.00).
Does the eSIM work on the islands and ferries?
On the islands, yes — Santorini, Mykonos, Crete, Rhodes and Corfu are covered like the mainland. On ferries you’ll have signal near ports and coastlines, with gaps mid-crossing on longer routes.
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. Airalo publishes its numbers on the plan card; most travelers never come close to either limit on a normal day of maps, messaging and social.
Does my WhatsApp number keep working?
Yes, on both. These eSIMs are data-only; your home SIM stays installed for calls and SMS codes, and WhatsApp keeps your existing number.
When does the AeroSims plan start counting?
Unlimited plans start when the eSIM first connects to a Greek network — not at purchase. Packages count gigabytes, not days, within their 30-day validity. Install at home before you fly and lose nothing.

Bottom line
Airalo is the polished giant, and its Greek unlimited plans genuinely undercut ours at standard lengths — we printed every number. But most Greece trips run on 5–10 GB of maps, ferries and photo uploads, and there Airalo has no answer to $4.90 and $8.90. Buy the data you’ll actually use, and spend the difference on the good table by the water.
