RedEx eSIM does not provide a truly unlimited data eSIM for Greece. All plans that use “unlimited” in their name actually include a finite high‑speed data allowance, such as 1 GB, 2 GB or 3 GB, after which the speed is reduced to 384 kbps or 5 Mbps. Travelers who need a large amount of data can choose fixed data plans instead, for example a 500 GB, 200 GB or 100 GB bundle that remains available for a set period (90 days, 30 days, etc.). These fixed plans offer more data and can be cost‑effective unless the user is a very heavy data consumer.
