Best eSIM for Greece (2026)
Checked 2026-06.
Checked 2026-06: for most travelers heading to Greece, Saily is the better-value pick because it generally rides a stronger Greek network (Vodafone / Wind Hellas, with some listings citing Cosmote) than Airalo, which in Greece runs on the weaker Nova/Wind network — at broadly similar prices. Both are legitimate, app-based, data-only travel eSIMs.
At comparable prices, Saily's Greece plans generally connect to a stronger host network (Vodafone / Wind Hellas, with some listings citing Cosmote) than Airalo's Nova/Wind footprint — which matters most for island-hopping and rural/ferry routes where coverage gaps appear. Saily also lists clear unlimited options with a 5 GB/day high-speed fair-use cap. Airalo remains a solid alternative with a larger plan catalog, but for raw Greek coverage Saily has the edge as of 2026-06. Confirm the exact host network and price on the provider page before buying, since both rotate carrier partners and run promos.

| Option | Data | Validity | Price | Notes |
|---|---|---|---|---|
| Saily (our pick) | ~1 GB to 20 GB+, plus unlimited | 7 / 15 / 30 days; unlimited 5-30 days | ~$4-5 (1 GB) to ~$22 (10-20 GB); unlimited ~$47-49 / 15 days | Generally stronger network (Vodafone / Wind Hellas; some listings cite Cosmote). Unlimited has 5 GB/day high-speed cap. Data-only. Ranges, checked 2026-06. |
| Airalo | ~1 GB to 10 GB+, plus unlimited tiers | 7 / 15 / 30 days | ~$4-7 (1 GB) to ~$20 (10 GB / 30 days) | Largest plan catalog, but in Greece runs on the weaker Nova/Wind network. Data-only. Ranges, checked 2026-06. |
| Carrier roaming | Uses your home allowance | Per your home plan | Free within EU fair-use cap; non-EU often ~€6-12/day or pay-per-MB | Best if you're an EU resident with EU roaming. Non-EU pay-per-use can be very costly. Checked 2026-06. |
| Local Greek SIM | Tourist packs, often 10 GB+ | Often 30 days | Roughly €15-30 at shops/airport | Top network directly, but needs ID, a shop visit and a SIM swap. Less convenient than an eSIM. Checked 2026-06. |
Networks and coverage. Greece has three main networks: Cosmote (widest rural and island coverage, generally the safest for ferries and remote areas), Vodafone (strong in cities, coast and tourist islands; reliable in remote spots), and Nova/Wind (fine in cities but weakest once you leave them). This is the heart of the Airalo-vs-Saily call: as of 2026-06, multiple comparison sources report Airalo's Greece eSIM connects to the Nova/Wind network — the weakest of the three — while Saily generally rides Vodafone / Wind Hellas (some listings instead cite Cosmote). Host networks can change without notice, so check the live provider page, but on current data Saily has the coverage advantage where it counts: islands and inland.
Activation and setup. Both are app-based, data-only eSIMs (no Greek phone number or SMS — use WhatsApp, iMessage or Telegram for calls and texts). You buy in the app, install the eSIM by QR code or one-tap before you fly, and it activates when you arrive and connect — so you land with data ready. Saily lists roughly a 30-day window before an unused plan auto-activates; Airalo's validity clock starts when the eSIM first connects. Check your phone is eSIM-capable and carrier-unlocked first.
Sizing your data. Most short Greece trips run comfortably on 3-10 GB. As a rough guide (2026-06): light use (maps, messaging, email) 1-3 GB/week; moderate use with some social and photos 5-10 GB/week; heavy streaming or hotspot use, pick unlimited. Both providers sell fixed bundles from about 1 GB up through 20 GB+, plus unlimited tiers; Saily's unlimited carries a 5 GB/day high-speed fair-use cap, after which speeds may slow. Use the on-site tool linked on this page to size your plan against your trip length.
Validity and plan length. Typical validity runs 7, 15 or 30 days on fixed bundles; both also offer multi-day unlimited options (commonly 5-30 days). Validity is the lesser of your time window and your data — whichever runs out first. Match the validity to your trip plus a buffer day, and don't over-buy data you can't use before it expires.
The gotcha. EU and EEA residents may already be covered by free EU roaming on their home plan (subject to fair-use data caps) — for them a travel eSIM is often unnecessary, so check your existing allowance first. The eSIM math is strongest for non-EU travelers (US, UK, Australia, etc.), where home-network roaming in Greece can be punishingly expensive. Either way, prices and host networks below are dated ranges, not fixed quotes — confirm the current figure on the provider page before buying.

FAQ
Which is better for Greece, Airalo or Saily?
As of 2026-06, Saily is the stronger pick for most travelers because its Greece plans generally connect to a better network (Vodafone / Wind Hellas, with some listings citing Cosmote), while Airalo runs on the weaker Nova/Wind network there — at broadly similar prices. Airalo is still a solid alternative with a larger catalog. Host networks can change, so confirm on the provider page.
Which network gives the best coverage on the Greek islands?
For island-hopping and rural or ferry routes, Cosmote and Vodafone have the strongest footprints; Nova/Wind is weakest outside cities. Choose an eSIM that rides Cosmote or Vodafone for the most reliable island coverage. Provider host networks vary and can change, so verify before buying.
How much data do I need for a week in Greece?
A rough 2026-06 guide: 1-3 GB for light use (maps and messaging), 5-10 GB for moderate use with social and photos, and an unlimited plan if you'll stream or use a hotspot heavily. Use the tool on this page to size against your trip length.
Do I need a travel eSIM if I live in the EU?
Often not — EU and EEA residents usually have free EU roaming in Greece on their home plan, subject to fair-use data caps, so check your existing allowance first. Travel eSIMs make the most sense for non-EU travelers, where carrier roaming in Greece can be very expensive.
