Summary
For a 2026 Greece trip, a capped-data eSIM from ~US$4 on Cosmote or Vodafone Greece is the cheapest way to stay connected across Athens, Santorini, and the islands. YonoSIM and Airalo both sell small tiered bundles; Holafly's unlimited plans cost more and only pay off if you stream heavily. Here is how the three compare.
The three eSIM options for Greece
All three run on Greece's main networks — Cosmote (the largest) and Vodafone Greece— so raw coverage across Athens, Thessaloniki, and the Cyclades is similar. The difference is pricing model. YonoSIM and Airalo sell capped bundles (you pick 1–10 GB); Holafly leans on unlimited plans priced per day. For a typical week of maps, bookings, and social posts, a capped plan is cheaper; unlimited only wins for constant streaming.

FAQ
QWhich eSIM is cheapest for Greece in 2026?
AFor most travelers, a capped-data plan is cheapest — YonoSIM starts around US$4 for a few GB on Cosmote or Vodafone Greece. Airalo's small bundles are similar. Holafly's unlimited plans cost more per day and only pay off if you stream heavily. Match the plan to your actual usage rather than defaulting to unlimited.
QDoes an eSIM work across the Greek islands?
AYes. Cosmote and Vodafone Greece cover Athens, Thessaloniki, and the popular islands — Santorini, Mykonos, Crete, Rhodes, Corfu — including most ferry routes near the coast. A travel eSIM rides those networks. Signal can dip mid-crossing on longer ferries, so download offline maps before you sail.
QCan I keep my home number while using a Greece eSIM?
AYes. The eSIM is a data-only second line. Keep your home SIM in the phone with data roaming off, and your number still receives calls and texts over Wi-Fi calling while the eSIM handles cheap Greek data.
QHow much data do I need for a week in Greece?
AFor a 7-day trip, 3–5 GB covers maps, ferry and restaurant bookings, social posts, and messaging. Heavy video streaming or hotspotting a laptop pushes you toward 10 GB or an unlimited plan. Most island-hoppers do fine on 5 GB.
Bottom line
For Greece in 2026, YonoSIM's capped bundles from ~US$4 give most travelers the best value on the same Cosmote/Vodafone networks Airalo and Holafly use — save unlimited for heavy streamers. Install on Wi-Fi before you fly and keep your home number for calls. Compare with the Santorini eSIM vs roaming guide or browse all Greece eSIM options for 2026.
