Best eSIM for Greece 2026: 16 Providers Compared

On a Greek trip, the signal is strong on Santorini and along Crete's north coast but can fade on Folegandros or halfway through a long ferry crossing, so which network your eSIM uses matters more here than in most of Europe. eSIM plans for Greece start at $3.92 for 1 GB -- less than a gyro in Monastiraki Square. But with thousands of islands scattered across the Aegean and Ionian seas, coverage quality between Athens and a remote beach on Milos can vary dramatically. Choosing the best eSIM for Greece means finding a provider that keeps you connected on Santorini's caldera, Crete's mountain roads, and the ferry ride in between.

Cosmote, Vodafone or Nova: the 2025 nPerf numbers for Greece

Greece has three networks, and one clear leader. In the nPerf 2025 mobile barometer, covering the whole of 2025, Cosmote scored 89,007 nPoints with a median download speed of 163.18 Mbps, well ahead of Vodafone (75,442 nPoints, 83.62 Mbps) and Nova, the former Wind (69,083 nPoints, 62.65 Mbps).

Cosmote, part of the OTE group, also has the widest reach on the small islands and in mountain villages. Vodafone and Nova are strong in Athens, Thessaloniki and the main tourist islands, which is where most visitors spend their time. Many travel eSIMs for Greece use Vodafone or Nova; the networks used by each Simsima plan are listed in its details, which is worth a look if your route includes the quieter islands.

What Does an eSIM for Greece Actually Cost?

Greece eSIM pricing splits into two categories: unlimited data plans (sold by duration) and capped plans (sold by total data allowance). Both types are available from multiple providers, and prices range widely. The tables below show verified current prices.

Unlimited Data Plans

Unlimited plans are ideal if you do not want to monitor your data usage; speed is reduced after a daily high-speed allowance, until the next day. They are priced by how many days they last, with costs varying significantly between providers for the same duration.

Capped Data Plans

If you know roughly how much data you need, capped plans offer a fixed allowance -- typically over 7 or 30 days. These can be more cost-effective for light to moderate users who rely on hotel Wi-Fi for heavy tasks.

Simsima offers both unlimited and capped plans for Greece with instant digital delivery -- no shipping, no store visit, no ID or registration required. If your trip extends beyond Greece into neighboring countries, Simsima's multi-country Trip Packs cover multiple destinations on a single eSIM.

Buying a SIM in Athens, and when your home plan already works

Cosmote, Vodafone and Nova all sell prepaid SIMs in their stores, including at Athens International Airport and around Syntagma, and you will need your passport to register the line. The networks are licensed by the Hellenic Telecommunications and Post Commission (EETT). A local SIM gives you a Greek number, which some island taxi services and small hotels still prefer for calls.

Many visitors do not need one at all. If your SIM comes from another EU country, Iceland, Liechtenstein or Norway, you roam in Greece at domestic prices within your operator's fair-use limit, as the EU's Your Europe roaming guide sets out. Travelers from the UK, the US, Canada or Australia pay their carrier's roaming rates instead, which is where a Greece eSIM, set up before the flight to Athens, earns its place.

Install Your eSIM Before Landing in Greece

You do not need to wait until you arrive in Greece to set up your eSIM. Installing the profile before departure means you will have data as soon as your plane touches down at Athens International, Thessaloniki, or any Greek airport. The process is the same across all major eSIM providers.

1. Confirm your phone supports eSIM and is carrier-unlocked. Most iPhones from the XS onward, Samsung Galaxy S20 and newer, Google Pixel 3a and newer, and recent Motorola devices support eSIM. Not sure? Check your device on the eSIM-compatible devices page.
2. Choose a Greece eSIM plan based on your trip length and data needs. A 3-day or 7-day unlimited plan works well for short holidays. For trips of two weeks or more, compare the 15-day and 30-day options in the tables above.
3. Open your phone's eSIM settings and scan the QR code. On iPhone: Settings > Cellular > Add eSIM > Use QR Code. On Android: Settings > Network & Internet > SIMs > Add eSIM. The profile installs in about 30 seconds.
4. Label your new eSIM line (e.g., 'Greece Travel') and set it as your data line. It connects to a Greek network on its own once you land, usually within a minute or two.

A stable Wi-Fi connection is needed during the QR code scanning step, so install your eSIM at home or at your departure airport before boarding. Some providers also support direct app-based installation without a QR code.

Santorini to Folegandros: island coverage and ferry crossings

The big islands are straightforward. Santorini, Mykonos, Paros, Naxos, Rhodes, Corfu, Zakynthos and the north coast of Crete from Chania to Heraklion have strong 4G and often 5G in the towns and on the main beaches. The smaller Cyclades such as Folegandros, Sikinos and Anafi, and remote Dodecanese islands such as Kastellorizo, have coverage centered on the port and the main village.

Inland and at sea, expect gaps. The Samaria Gorge, the south coast of Crete around Loutro and Agia Roumeli, and the mountain villages of Naxos and Rhodes can lose signal. Short ferry hops such as Paros to Naxos stay connected most of the way, but the long runs from Piraeus to Crete or to the eastern islands go quiet in the open Aegean. Save your ferry tickets offline before boarding.

Data for two weeks of island hopping: Athens, Naxos and Santorini

A classic route spends three nights in Athens, then takes the ferry to Paros or Naxos for four or five nights and on to Santorini or Milos. Ferry apps such as Ferryhopper, maps for renting a scooter, beach-bar searches and plenty of photo sharing make for steady daily use.

• Two weeks of maps, ferry bookings, messaging and social media: about 8 to 10 GB
• Add daily video calls or uploading reels from the beach: 15 to 20 GB
• A month of remote work from an island, or a family sharing one hotspot: an unlimited plan from the table, if the plan allows tethering

Hotels and tavernas almost always have Wi-Fi, so the heavy uploads can wait for the evening.

Downsides of an eSIM in Greece

• No Greek number: island taxi ranks and some small hotels confirm by phone call, so keep your home number or WhatsApp reachable
• Network matters on the quiet islands: a plan that uses Vodafone or Nova may be weaker on Folegandros or Kastellorizo than one with access to Cosmote
• EU visitors may not need it, since their home plan already roams in Greece at domestic prices
• Your phone must support eSIM and be carrier-unlocked, and sharing data with a laptop on a ferry depends on the plan
