ZenSim does not have any true unlimited data eSIM plans for Greece. Every plan lists a fixed data cap, with the maximum daily allowance of 3 GB/day, which is reduced after the daily limit is reached. Plans that carry the label “Unlimited” simply include that name but still provide the 3 GB/day allowance rather than an uncapped data volume.
Travelers who require a larger data allowance can choose among ZenSim’s fixed‑data options. For example, the Greece 20GB 10‑day plan provides 20 GB of high‑speed data for $26.00 USD, and the same amount is available for 30 days for $29.00 USD. Selecting a fixed data plan can be more cost‑effective than a daily‑cap plan for users who anticipate heavy data usage during their trip.
