For island-hopping, network choice beats price. Cosmote has the best reach on the smaller Cyclades and Dodecanese — and sells to no travel eSIM brand, so the real question is which of the rest you get. YonoSIM rides Vodafone and Wind; Vodafone is the strongest Greek network you can actually buy. A 10 GB plan covers a week of island-hopping.

QWhich Greek network do travel eSIMs use?
ACosmote has the widest island coverage but does not supply travel eSIM brands. YonoSIM publishes Vodafone and Wind; Airalo publishes Nova and Vodafone. Both therefore reach Vodafone Greece, the strongest of the reachable networks on the smaller Cyclades. Saily, Holafly, and Nomad do not publish a Greek carrier at all, so you cannot check before buying.
Explore our regional and global eSIMs — packages start from the shown price and include coverage for the selected location.
For a 2026 Greece trip, YonoSIM starts at a few dollars for capped data on Vodafone Greece. Airalo offers small tiered bundles and Holafly sells pricier unlimited. Here's how the three compare for Athens, Santorini, and island hopping.
QWhich Greek carrier has the best island coverage?
ACosmote has the most reliable coverage on smaller Cyclades and Dodecanese islands — the only carrier you can count on across remote island-hopping itineraries. Vodafone is solid on Santorini, Mykonos, and Crete; Wind/Nova is weakest on islands.
QHow much data do I need for a Greece island-hopping trip?
A5–10 GB covers a typical 1–2 week trip with maps, ferry apps, social uploads, and video calls. A 10 GB plan runs a few dollars for 30 days; heavy users should pick unlimited.
QIs there 5G on the Greek islands?
AMost islands run on 4G LTE (20–60 Mbps), which is more than enough for streaming and video calls. 5G is concentrated in Athens and Thessaloniki, where Cosmote leads. For islands, 4G coverage breadth matters more than 5G speed.
QWill a Europe-regional eSIM cover Greece?
AYes — Greece is an EU member, so any regional Europe travel eSIM works. But for island-heavy trips, check which network the plan actually rides: Cosmote has the best island reach and sells to no travel eSIM brand, so Vodafone-backed single-country Greece plan is the safer pick.
For island-hopping, network choice beats price: Cosmote reaches the smaller Cyclades and Dodecanese most completely but sells to no travel eSIM, which makes Vodafone, solid on Santorini, Mykonos and Crete, the strongest Greek network you can actually buy, and our plans ride Vodafone and Wind. A 10 GB plan covers a week of ferries, maps and uploads; on the smallest islands only a local Cosmote SIM does better.
Our Greece plans run on Vodafone and Wind with 5G where the network has it; traffic exits through FR/NL/UK. 20 plans, hotspot allowed on every one, activation within 180 days of purchase.
