eSimfly does not provide a truly unlimited data eSIM for Germany. All of its plans that carry “Unlimited” in the name actually offer a fixed amount of high‑speed data—most commonly 3GB per day—with a reduced speed of 1000kbps applied once that daily limit is reached. For travelers who need a larger data allowance, eSimfly offers fixed data plans such as the Germany Unlimited 30 days plan, which provides 3GB per day for 30 days, or the O2 Unlimited (International) plan, which gives 35GB for 30 days. These plans are more cost‑effective for most users unless they require continuous, unrestricted high‑speed data.
