Flysimio does not provide a truly unlimited high‑speed data eSIM for Denmark. The plan labeled "Denmark Unlimited" offers a 2GB/day allowance and is valid for 7 days, so after the 2 GB each day the speed is reduced; it is not an unlimited data plan.
Instead, Flysimio offers fixed data plans that give larger caps, such as the Denmark 50GB 180‑day plan and various Europe‑wide 50GB bundles that keep the same high‑speed data amount for longer validity periods. These plans can be a more cost‑effective option unless a traveler needs a constant high‑speed data supply beyond the daily or total limits.
