ByteSIM does not provide a truly unlimited data eSIM for Greece. The plans that carry the word “Unlimited” in their name actually offer 1GB per day and, once that amount is reached, the speed is reduced to 10000kbps. Therefore, these plans are not unlimited in the sense of providing high‑speed data without limits.
Travelers who need a larger data allowance can choose from ByteSIM’s fixed data plans. For example, the 50GB plans are available for 3 to 15 days, with prices ranging from $40.90 for 3 days to $51.90 for 15 days. These fixed data plans give a substantial amount of high‑speed data and can be more cost‑effective for most users.
