Best eSIM for Greece 2026: 14 Providers Tested & Compared

Looking for the best eSIM for Greece? In May 2026 I tested 14 eSIM providers across Greece to find out which ones actually deliver, and which ones to avoid.

Roaming costs can add up quickly in Greece. Many carriers charge daily fees or cap your data abroad, so it pays to check your plan before you fly. For travelers without inclusive roaming, a travel eSIM is usually the cheapest way to stay connected in Greece.

Two things to watch out for:

• Daily roaming fees can add up. On many plans, a two-week trip can add a significant amount in roaming charges, while a 10 GB eSIM often costs only a fraction of that.
• The eastern Greek islands hide a costly trap. On Lesvos, Chios, Samos, Kos and Rhodes your phone can silently connect to a Turkish mast. Turkey sits outside the EU, and European travelers have been hit with bills in the thousands.

For most travelers, a travel eSIM is the simplest answer. In this article you'll find my top picks.

How to Choose the Right eSIM for Greece?

Have you decided an eSIM is the right choice for you? Then the best option mostly comes down to what you'll be doing online.

For most travelers, the choice of network in Greece makes little difference. All three Greek networks (Cosmote, Vodafone and Nova) deliver solid 4G and 5G in tourist areas and major cities. The network only really matters if you're heading to remote areas: smaller islands, mountain villages on the mainland, or the less-visited parts of the Peloponnese. Cosmote has the widest coverage in remote areas.

I tested 14 providers and four stood out:

• GoMoWorldfor the best value for money, with the highest speeds in my test
• Ubigifor European plans, with the most stable connection and strong performance if you're also traveling to Turkey or Albania
• Airalofor ease of use, with the best response time in my test and the most user-friendly app
• Orange Travelif you genuinely need unlimited data, with the only bundle without a real fair use cap. Only worthwhile if you know you'll use a lot of data; for most travelers it's a waste of money.

How much data do you actually need? It pays to think about this beforehand. Use our data calculator to estimate what you'll really use on your trip. Want to compare prices? Browse all 35+ providers via our Greece eSIM comparison tool. Or read on for my personal review.

All 14 Providers Tested

All providers were personally tested by me in May 2026 under the same conditions, with an iPhone 16 Pro in Athens.

For speed I used the Ookla speedtest, and for response time meter.net. Most people only look at download speed, but response time matters just as much. A fast download with slow response time still feels sluggish: video calls stutter, web pages take seconds to start loading, and games are unplayable.

GoMoWorld and Ubigi clearly stood out as the winners. Holafly, Pingwe (a European plan) and Eskimo were more limited and not recommended for video calls or remote work. Pingwe's low price can still make it worthwhile in some cases.

For Pingwe and GoMoWorld I tested a European plan, which may differ from the local offering. Routing (which country the data passes through) is listed too, but providers can change this at any time.

Local networks in Greece

These are the mobile networks in Greece:

• Cosmote
• Vodafone
• Nova

Sticking to tourist areas or major cities?

In Athens, Thessaloniki and on popular islands like Crete, Rhodes, Mykonos, Santorini and Corfu, all three networks work perfectly well. 5G is widely available in the major cities and tourist areas. During my trip to Greece (May 2026) I had near-constant 5G coverage, even outside city centers. For an average city break or beach vacation, it doesn't really matter which network your eSIM uses. Many travel eSIMs also work across multiple Greek networks at once.

During my testing, eSIMs on the Nova network performed strongest on average. Not because Nova has the best network as such; roaming agreements undoubtedly play a part too. But for a regular trip where you're not venturing off the beaten track, network choice in Greece isn't something to lose sleep over.

Heading somewhere more remote?

Traveling to smaller islands, mountain villages on the mainland, or the less-visited parts of the Peloponnese? Then it's a different story. On those routes, Cosmote has the widest coverage. One important caveat: very few travel eSIMs work on Cosmote. Most eSIM providers use Vodafone GR or Nova as their local partner. For travelers heading genuinely off the beaten path who want certainty, a local Cosmote SIM is sometimes the better choice.

Going to the eastern islands?

Lesvos, Chios, Samos, Kos and Rhodes sit just a few kilometers off the Turkish coast. There your phone can unwittingly connect to a Turkish mast, which leads to high roaming charges outside the EU. An eSIM that only works on Greek networks prevents this risk. Read more about Turkish roaming charges on Greek islands.

Buying a local SIM card

Many travelers will get the best value with a travel eSIM, especially if their plan doesn't include EU roaming. But if you need a local Greek number, or specifically want a local Cosmote SIM for better coverage, then a local SIM card is sometimes the better choice.

During my trip, the only eSIMs I could find at Athens International Airport (ATH) were from Vodafone, sold via two Sim Local stores. The Sim Local shop by baggage reclaim was open, but the one in the arrivals hall was unexpectedly closed despite it being busy and nearly peak season. According to the Sim Local website the kiosk should have been open, but it wasn't. Walking back to the baggage hall isn't possible at that point.

The prices were on the higher side too:

• 35 euros for 25 GB and 100 minutes
• 50 euros for 300 GB and 100 minutes

Compared to a travel eSIM (which you can get for just a few dollars), these bundles are fairly pricey with a high entry point. On top of that, Vodafone isn't the strongest network in Greece, especially in remote areas and on smaller islands. Personally, I wouldn't go for this option. Sim Local doesn't sell Vodafone SIM cards online either; they're only available at the airport.

Important to know: buying a Greek SIM card requires ID. You'll need to show your passport, and the seller registers your details. This is required by law and applies to all Greek operators.

At Athens airport I couldn't find any Cosmote or Nova vendors on-site. For other Greek airports (Heraklion, Thessaloniki, Mykonos, Santorini, Rhodes) the picture is less clear. Some sources mention operator kiosks, but I haven't been able to verify this myself. Want to be sure of a specific network? Buy an eSIM before you fly, or plan a visit to a Cosmote shop in the city.
