GigSky does not offer an unlimited data plan for Greece. All available eSIM options come with a fixed data allowance, such as the World Plan Lite 100GB valid for 180 days or the Greece 50GB plan also valid for 180 days.
If a traveler requires a large data volume, these fixed data plans can be cost effective. The World Plan Lite, for example, provides 100GB of data at $179.99 USD, while the Greece plan offers 50GB for $40.89 USD. Both plans are available for the same validity period of 180 days.
