eSimfly does not provide a true unlimited data eSIM for Denmark. The plans that carry “Unlimited” in their names actually limit high‑speed data to a fixed amount – for example, Denmark Unlimited 30 Days offers 3GB per day or O2 Unlimited (International) provides 35GB for 30 days before speed reduction occurs.
If a traveler needs a large data allowance, eSimfly offers fixed‑data options. A 30‑day plan with 3GB/day, such as Denmark Unlimited 30 Days, or a higher‑capacity bundle like O2 Unlimited 35GB for 30 days, are suitable substitutes. These fixed‑data plans provide a clear limit and expiry timeline, and many users find them more cost‑effective unless they require truly limitless data.
