No, nextSIM does not offer a truly unlimited high‑speed data eSIM for Romania. The plans listed under the “Unlimited” name give a fixed amount of high‑speed data—typically 1GB per day or 2GB per day—and once that limit is reached, the speed drops to a throttled rate such as 512kbps or 2000kbps.
Travelers who need more data can choose from fixed‑data plans instead, such as the eSIM Pro Romania 200GB plan valid for 120 days or the eSIM Pro Romania 150GB plan valid for 60 days. These provide a large, capped amount of data at full 5G speed without the post‑limit speed reduction. However, if someone requires truly unlimited usage, a fixed‑data plan may still be a more cost‑effective option for heavy data consumers.
