No, nextSIM does not provide a truly unlimited data eSIM for Germany. All plans labeled with “Unlimited” in the name contain a fixed high‑speed data allowance, after which the speed is reduced (for example, 512kbps or 2000kbps).
Travelers looking for larger data allowances can choose from the fixed‑data offerings available on nextSIM. For instance, the eSIM Pro Germany 200GB plans give 200GB of high‑speed data for 30, 60, 90, 120, or 180 days, and the eSIM Unlimited Standard or Plus plans provide 1GB or 2GB per day for up to 30 days, respectively. These options may offer a more cost‑effective solution for heavy data usage compared to the limited “Unlimited” plans.
