Best eSIM for Greece in 2026
Our value pick for Greece is eSimania, at about $2.01 for 1 GB or $8.64 for 5 GB over 30 days, which undercuts Airalo on both sizes and on validity (about $4.00 for 1 GB over 3 days, about $12.00 for 5 GB over 30 days). Jetpac is the one-install option. Visiting more of Europe? A Europe eSIM covers Greece plus about 35 countries on one plan. For a week, 3 to 5 GB is plenty on Cosmote, Vodafone or Nova. Prices verified July 28, 2026; speeds are carrier-dependent and never guaranteed.
Greece is easy to stay connected in, from Athens to the islands, with strong 4G and 5G through Cosmote, Vodafone and Nova. A travel eSIM installs from a QR code before you fly, so you land already online. Below are the plans we route to, a dated price check, and how to size your data.

How much data you need in Greece
Coverage: mainland and islands
Greece has three mobile networks: Cosmote, Vodafone and Nova. It became three rather than four recently, and the regulator says so plainly. In its market review, the Hellenic Telecommunications and Post Commission (EETT) describes the NOVA and WIND merger as one of the largest structural changes in the sector and records that on completion "the number of operators offering mobile communications services ... was reduced to three". If a guide still lists Wind Hellas as a Greek network, that brand is inside Nova now. By total connections EETT put Cosmote at 46.5 percent, Vodafone at 30.6 percent and Nova at 22.8 percent. Source: EETT, market review.
We used to tell you that Cosmote had the widest coverage and to favour it for island hopping. We have withdrawn that, because we could not source it. The figures above are market share, not coverage, and having the most customers is not the same as reaching the most places. EETT publishes connection counts rather than a per-operator coverage ranking, so a claim about who reaches furthest across the islands has nothing official behind it and we are not going to invent one.
What holds regardless of network is the shape of the problem: Athens, Thessaloniki, the main and mid-size islands have good signal, while very small or remote islands, some beaches and boat crossings can be weaker on all three. So the practical advice for island hopping is not a carrier, it is preparation: download offline maps and your ferry tickets before you go. Because eSimania is a marketplace it does not name the exact network anyway. Speeds depend on the local carrier and are never guaranteed.
On roaming, Greece is inside the European roaming zone, so if your home plan comes from within it, Regulation (EU) 2022/612 lets you use your domestic allowance here at no surcharge until 2032. The European Commission lists the zone as the 27 EU member states, plus Iceland, Liechtenstein and Norway, with Ukraine and Moldova added on 1 January 2026. Greece is where that boundary is easiest to sail across: the short hops that make the eastern Aegean islands appealing, Kos or Rhodes or Samos over to the Turkish coast, land you in a country outside the zone, as would a trip north into Albania or North Macedonia. Your phone will switch networks quietly and your home rate will not follow you. Source: European Commission, roaming questions and answers. Prices checked August 15, 2026.
Frequently asked questions
How much eSIM data do I need for Greece?
For a typical 7-day trip, 3 to 5 GB covers maps, ferry and restaurant bookings, messaging and photos. Island hopping leans on maps and ferry apps, so 5 GB is a comfortable choice, while light users on hotel wifi can manage on 1 to 2 GB.
Will an eSIM work on the Greek islands?
Yes on the main and mid-size islands, which have good 4G and 5G through Cosmote, Vodafone and Nova. Very small or remote islands and some beaches can have weaker signal, so download offline maps and ferry tickets in advance if you are heading somewhere quiet.
Which Greek network is best for tourists?
Greece has three networks: Cosmote, Vodafone and Nova, which became three after EETT recorded the NOVA and WIND merger. We do not name a winner on coverage, because EETT publishes market share rather than a per-operator coverage ranking, and share is not reach. Athens, Thessaloniki and the main islands are fine on all three; very small islands, some beaches and boat crossings can be weak on any of them, so download offline maps and ferry tickets.
Should I get a Greece eSIM or a Europe eSIM?
If Greece is your only destination, a Greece plan is simplest and, with eSimania, very cheap. If your trip also visits other European countries, a Europe regional eSIM covering about 35 countries on one plan is usually better value overall. Compare both for your itinerary.
