nextSIM does not provide a true unlimited data eSIM for Germany. All plans marked “Unlimited” in the provider’s catalogue actually offer a fixed daily allowance—1 GB or 2 GB of high‑speed data per day—that is followed by a reduced speed of either 512 kbps or 2000 kbps once the daily quota is reached.
Travelers who need a larger, unthrottled data supply can choose one of the fixed‑data plans. For example, nextSIM sells a 200 GB plan that lasts 90 days, a 200 GB plan that runs 180 days, and a 200 GB plan that remains active for a full year. These packages give high‑speed data without the daily cut‑off that characterises the “Unlimited” offerings.
