Saily in Greece
The NordVPN team's eSIM is our overall pick for Greece. Here is exactly why, and the two things it does worse than rivals.

Saily vs the field where each one wins
| Saily | GigSky | Airalo | |
|---|---|---|---|
| 10GB / 30 days | $21.99 | $18.29 | $24.00 |
| Greek networks | Cosmote + Vodafone | Vodafone + Nova | Nova + Vodafone |
| Unlimited cap | 5GB/day | 3.5GB/day (daily plans) | 3GB/day → 1 Mbps |
| Trustpilot | 4.7 · 30,290 | 4.3 · 6,084 | 4.1 · 41,238 |
| Validity options | 7–30 days | up to 180 days | 3–365 days |
| Free trial | no | 500MB free | no |
| Regional plan w/ Turkey | no | no | Eurolink, 42 countries |
Saily takes the two columns that decide most Greek trips: the island-grade network pair and the biggest published unlimited cap. GigSky wins raw price and validity, Airalo wins reach. The scenario logic in the main guide is built on exactly this table.
Coverage in Greece why the network pair matters
| Where | What to expect on Saily |
|---|---|
| Athens, Thessaloniki | 5G on either network; speed-test reports run 30–120 Mbps in town |
| Big islands (Crete, Rhodes, Santorini) | Strong 4G/5G in towns and resort strips on both networks |
| Small islands and hill villages | The Saily case: Cosmote reaches where Nova-based rivals fade — Halki on Naxos, the Amorgos road, Folegandros cliffs |
| Ferries and crossings | Cosmote holds closest to shore and between nearby islands; mid-crossing on long routes everyone drops, download offline maps |
| Gorges and mountains (Samariá, Zagori) | Patchy for everyone; Cosmote gives the best odds at trailheads |
Why it wins and where it loses
The network is the product. Saily connects to Cosmote or Vodafone GR, whichever is stronger where you stand. On Cycladic ferries and in hill villages, that is the difference between a working map and a spinning wheel.
The unlimited cap is published and big. 5GB per day at full speed, the largest disclosed cap on the Greek market. A hotspot workday fits inside it; see the unlimited comparison for the full math.
The company behaves like a company. Nord Security ownership, responsive support, and a refund process that travelers confirm actually works. Trustpilot 4.7 across 30,290 reviews as of August 31, 2026.
Where it loses, plainly. Price per GB at the top end: 20GB costs $37.99 against Yesim's $25.50 and GigSky's $35.49 for 90 days. Validity caps at 30 days, so season-long stays are GigSky territory. And there is no free trial, which GigSky offers. If those are your cases, the main guide routes you right.
Buying and activating the two-minute version
- Buy in the Saily app or on the site at home on wifi; both track the same for us, and the app is where top-ups live anyway.
- Install when prompted, then keep the Greece line switched off. Purchase-to-activation window is generous, so buying a week early is fine.
- On landing: line on, data roaming on for the Saily line only, home SIM stays on for SMS with its data off.
- If nothing connects in 5 minutes: pick Cosmote or Vodafone GR manually in network settings, then restart. Saily supports both, so try the other one too.
Buy it or skip it the honest split
Buy Saily if
Your trip includes islands, ferries or villages: the Cosmote pair is the whole argument.
You want unlimited with a readable cap: 5GB/day is the market's largest published number.
You value a provider whose refunds and support have a paper trail of working.
Skip Saily if
You need 20GB+ on a budget: Yesim at $25.50 is 33% cheaper.
You stay past 30 days: GigSky's 90/180-day plans exist for exactly this.
Your route adds Turkey: only Airalo Eurolink covers both on one plan.
Questions on Saily
Does Saily work on the Greek islands?
Yes, and better than most: it uses Cosmote, the network with the strongest island and ferry-route coverage, plus Vodafone as backup. Download offline maps for long crossings anyway; mid-strait everyone drops.
When does the plan start counting?
On first connection to a Greek network, not at purchase. Install at home, land, switch on the line, and the clock starts then.
Can I hotspot with Saily?
Yes, on all plans. On unlimited, tethering counts toward the 5GB daily full-speed cap, which is still the most workable hotspot allowance on the market.
What is Saily's refund policy in practice?
Unused or non-working plans get refunded through support, and traveler reports confirm the process functions rather than stonewalls, a meaningful difference from budget rivals. Keep screenshots of any connection failure to speed it up.
Is the Saily app required?
No, the QR flow works app-free, but the app handles installation, top-ups and plan switching in fewer steps, and shows a live data meter that has saved more than one traveler from bill-shock roaming on the wrong line.
Saily or a local Cosmote SIM?
Same towers, different paperwork. The shop route gets you a Greek number at the cost of a passport-registration errand; Saily gets you the coverage in two minutes from your sofa. The full comparison covers the edge cases.
