Compare eSIMs for Greece 2026

Vodafone, Wind and Cosmote are the networks listed by providers for Greece, in that order of stated reach. Most major travel eSIM brands list the country, including RedEx eSIM, AbestESIM, Roamix, MicroESIM, AirHub and Stellar eSIM, but their catalogues are not interchangeable. The practical differences are the amount of data, how long it remains valid and what happens when the allowance runs out, rather than the brand name alone. A familiar provider may offer several options, while another may suit a short visit or heavier use better.

Vodafone, Wind and Cosmote are the Greek operators named in travel eSIM listings. That gives buyers a genuine choice of network underneath the eSIM, although the choice is usually made by the provider rather than at the point of connection. The plan you select can therefore determine which operator it uses. Providers’ own published network details should make that clear in advance, so the operator is not an unknown that only becomes apparent after arrival.

A zero-cost data option is currently listed for Greece, but it is a small introductory allowance rather than a trip-sized plan. It usually requires an account and is limited to one use per customer. That makes it useful for getting online briefly after arrival or checking compatibility, not for regular use throughout a holiday. Greece is covered by most major eSIM sellers, so this free offer is best treated as a promotional sample rather than the usual way to get travel data.

Unlimited options are part of the Greek eSIM market, with most larger providers offering some version of them. The label needs careful reading: one plan may give you a fresh full-speed allowance each day, while another may slow down after its allowance for the remainder of the trip. Once throttled, messaging may still be fine, but video, hotspot use and image-heavy browsing can become frustrating. Check the reset schedule and reduced speed before choosing.
