Roamingo’s plans for Greece that contain the word “Unlimited” actually come with a fixed high‑speed data allowance of 2 GB. Once that limit is reached the speed is throttled, so the plans are not truly unlimited in the sense of providing an open, unlimited data stream.
If a traveler needs more high‑speed data, Roamingo also offers fixed‑data plans that can be more cost effective for heavier usage. For example, the Greece 20GB for 30 days plan costs $29.10 USD, and the Greece 10GB for 30 days plan is $16.40 USD. These options give a larger flat data allocation before any reduction in speed applies.
