ETravelSim does not provide a true unlimited data eSIM for Greece. Plans that carry “Unlimited” in their names actually offer 4GB of high‑speed data per day; once the 4GB/day limit is reached the network throttles the speed to 128kbps. This means that after using 4GB in a day the remaining data is still available, but it is at a reduced speed.
Customers who need a larger, continuous data allowance can choose from fixed‑data plans. For example, the Travel eSIM for Europe 50 GB – 30 days / Data Only plan gives 50 GB for a full 30‑day period and the government‑issued Greece eSIM – 30 days / Data Only delivers 30 GB for 30 days. These fixed plans do not thott at 4GB/day and can be more cost‑effective for travelers who expect to use a substantial amount of data.
