What Greece data actually costs
Greece travel eSIM prices look random until you convert every plan to one number: the real cost per gigabyte. Here is what that reveals right now.
The cheapest plan at each size, 30 days
| Data | Cheapest provider | Total | Price per GB | |
|---|---|---|---|---|
| 50 GB | Nomad | $31 | $0.62/GB | Get plan ↗🏷 20% off with code ATESIM |
| 25 GB | Ubigi | $22 | $0.88/GB | Get plan ↗🏷 10% off with code TRAVELCITY10 |
| 20 GB | Yesim | $20.48 | $1.02/GB | Get plan ↗🏷 15% off with code TRAVELCITY |
| 10 GB | Ubigi | $12 | $1.20/GB | Get plan ↗🏷 10% off with code TRAVELCITY10 |
| 5 GB | Sim Local | $9.75 | $1.95/GB | Get plan ↗🏷 10% off with code ATESIM |
| 1 GB | Yesim | $2.62 | $2.62/GB | Get plan ↗🏷 15% off with code TRAVELCITY |
Cost per GB rises from $0.62/GB at 50 GB to $2.62/GB at 1 GB. Buying a little more data than you expect to use is almost always cheaper per gigabyte than buying exactly what you need.
The "unlimited" trap
The same words, unlimited for 30 days, cover a wide price range, and most plans slow down after a daily threshold that the label hides.
| Provider | Unlimited, 30 days | Fair-use cap | |
|---|---|---|---|
| Maya | $49.99 | 3 GB/day, then 10 Mbps source | Get plan ↗🏷 10% off with code ATESIM |
| Ubigi | $55 | Not published | Get plan ↗🏷 10% off with code TRAVELCITY10 |
| GigSky | $65.49 | 2.5 GB/day, then reduced, but not below 100 kbps source | Get plan ↗🏷 15% off with code ATESIM |
| Airalo | $69 | 3 GB/day, then 1 Mbps source | Get plan ↗ |
| Saily | $71.99 | 5 GB/day, then 1 Mbps source | Get plan ↗ |
Unlimited 30 day plans run from $49.99 to $71.99, a spread of about 44 percent, for a label that means the same thing on paper. Check the daily cap before you buy, especially if you plan to tether a laptop.
Do not overpay for coverage you will not use
If your whole trip is in Greece, a Greece only plan is far cheaper per gigabyte than a Europe or global plan carrying the same data. Same provider (Nomad), same 50 GB, 30 days:
| Nomad plan | Price | Price per GB | |
|---|---|---|---|
| Greece only | $31 | $0.62/GB | Get plan ↗🏷 20% off with code ATESIM |
| Europe | $35 | $0.70/GB | Get plan ↗🏷 20% off with code ATESIM |
| Global | $129 | $2.58/GB | Get plan ↗🏷 20% off with code ATESIM |
A Greece only plan costs much less per gigabyte than a regional or global plan with the same data. Only pay for the wider plan if you are actually crossing borders on this trip.
Which network does your Greece eSIM use?
This is the question that decides your real signal, and almost no comparison site answers it. Your travel eSIM connects to one or more local networks as a visitor, and that choice matters the moment you leave the big cities, because rural coverage varies a lot between them.
| Provider | Host network | Status |
|---|---|---|
| Airalo | Not publicly disclosed | Confirming |
| GigSky | Not publicly disclosed (markets multi-network access) | Confirming |
| Ubigi | Nova | Confirmed |
| Nomad | Not publicly disclosed | Confirming |
| Saily | Not publicly disclosed | Confirming |
| Yesim | Not publicly disclosed | Confirming |
Cosmote is the strongest network for rural areas and small islands, so an eSIM confirmed on Cosmote is safest for island hopping; of these six only Ubigi discloses its network, and it uses Nova, the weakest of the three for remote coverage.
Coverage by where you are going
- Cosmote has the widest footprint, around 99 percent 4G of populated areas plus the best reach on small Cycladic and Dodecanese islands; Vodafone sits near 97 percent 4G and Nova near 94 percent.
- On remote beaches, mountain roads and inland island villages, Vodafone and Nova weaken while Cosmote usually holds, and the smallest islands may carry Cosmote only.
- 5G is live in Athens, Thessaloniki, Crete, Rhodes, Kos and Zakynthos; Cosmote runs 5G Standalone and leads on speed, averaging roughly 350 to 450 Mbps.
- The Athens Metro has underground mobile coverage, with 5G installed at Line 2 stations.
- Turkey border quirk: on islands near the Turkish coast your phone can connect to Turkcell or Turk Telecom, and because Turkey is not in the EU that data is billed as roaming rather than under an EU plan.
- Open-water ferry routes drop to weak or no signal regardless of which operator you are on.
Travel eSIM vs a local Greece SIM
An eSIM from Airalo, Ubigi, GigSky, Nomad, Saily or Yesim is the simple option for a week or two. You install it before you fly, land already connected, and pay a fixed price with no deposit or ID check. Greece is in the EU, so most of these plans also work across the rest of the EU on the same data allowance.
A local prepaid SIM from Cosmote, Vodafone or Nova makes sense for longer stays or if you want a Greek number and normal voice calls. You need your passport to register, and top-ups are easy at kiosks and supermarkets. Cosmote is the pick for island trips thanks to its wider rural and small-island coverage.
Quick rule: Under three weeks, use an eSIM; for longer stays or a local number, buy a Cosmote or Vodafone prepaid SIM.
Greece's three networks are Cosmote, Vodafone and Nova (Wind Hellas merged into Nova), and the main budget option is Frog Mobile, an MVNO on the Cosmote network with plans around 12 euros for 10GB; local plans include EU roaming.
How a Greece travel eSIM works
A travel eSIM replaces expensive roaming with a cheap local data plan you activate in seconds. There is no plastic SIM and no airport queue. Roaming with your home carrier can run 6 to 12 dollars a day, so a week easily tops 50 to 80 dollars for service you already pay for at home.
Three things to get right:
- Check your phone supports eSIM before you buy.
- Install the eSIM at home over WiFi, but wait to activate it until you land, because the validity period usually starts on activation.
- Keep your physical SIM in the phone for calls and texts on your normal number.
How we rank Greece eSIMs
Every plan on this page is sorted by real price per GB (total price divided by included data, normalised to USD), so a cheap-looking 1 GB plan cannot outrank a better-value 10 GB one. We refresh prices daily and only list providers with a track record of activating on arrival. We earn a small affiliate commission when you buy through our links. It funds the price tracking and never changes the order you see.
Greece travel eSIM FAQ
Which network is best for the Greek islands?
Cosmote has the widest reach and is often the only network with a usable signal on smaller Cycladic and Dodecanese islands. Vodafone and Nova are fine on large, popular islands but weaken on remote beaches and inland villages. If your trip includes small islands, favor an eSIM that runs on Cosmote.
Will my eSIM work across the rest of the EU?
Usually yes. Greece is in the EU, and most travel eSIMs sell regional Europe plans or apply the same allowance across EU countries. Check whether you bought a Greece-only or a Europe plan before you rely on it elsewhere.
Why does my phone show roaming charges near Turkey?
On eastern Aegean islands like Kos, Rhodes, Samos and Lesbos, your phone can pick up a Turkish network such as Turkcell or Turk Telecom. Turkey is not in the EU, so that data is billed as roaming. Set network selection to manual and lock onto a Greek network to avoid it.
Is there mobile signal on the Athens Metro?
Yes. The Athens Metro has underground mobile coverage, and 5G has been installed at Line 2 stations. Expect solid data at stations and on most of the network.
Do these eSIMs give me a Greek phone number?
No. All six providers sell data-only plans for Greece with no local number or SMS. You can still call and message over WhatsApp, Viber, Telegram or similar apps. For an actual Greek number, buy a local prepaid SIM.
Which is the strongest network overall in Greece?
Cosmote leads on coverage and 5G speed, with roughly 99 percent 4G of populated areas and average 5G speeds around 350 to 450 Mbps. Vodafone is a close second in cities and resort areas, while Nova trails on rural and small-island coverage.
