FullBars does not sell an unlimited‑data eSIM for Greece. All of its Greece‑specific plans have a fixed data cap, the largest being 50 GB for 30 days or 50 GB for 180 days if you include a broader European coverage. Travelers who need more data can choose one of these fixed data plans such as the Greece 50GB · 30 days plan or the Europe 50GB · 180 days plan, or opt for a larger daily allowance with the Greece 20GB · 30 days bundle. Fixed data plans can be more cost‑effective for most users, especially if they expect to stay in Greece for a defined period and use data within the allotted days.
