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 (about $4.00 for 1 GB and $11 to $14 for 5 GB). Jetpac is the budget option from about $1. 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 9, 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
Cosmote has the widest coverage in Greece, including many islands, with Vodafone and Nova strong in Athens, Thessaloniki and larger tourist areas. Main and mid-size islands have good signal; very small or remote islands and some beaches can be weaker. For island hopping, a plan roaming on Cosmote is the safest bet, and it is worth downloading offline maps and ferry tickets before you go.
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?
Cosmote has the widest coverage, including many islands, with Vodafone and Nova strong in Athens, Thessaloniki and larger tourist areas. For island hopping, a plan roaming on Cosmote tends to give the most reliable signal off the mainland.
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.
