No, nextSIM does not provide a truly unlimited data eSIM for Brunei. All plans that carry the “Unlimited” label have a fixed data cap; for example, the eSIM Unlimited Standard plans offer 1 GB per day and the eSIM Unlimited Plus plans offer 2 GB per day, after which the speed is throttled to either 512 kbps or 2000 kbps.
Travelers who need more data can choose from the fixed‑data options. A popular choice is the eSIM 3 GB 30 days plan, which gives 3 GB of high‑speed data over a month, and the eSIM 2 GB 15 days plan, which provides 2 GB for two weeks. These plans are often more cost‑effective for moderate‑to‑heavy data users than the higher‑priced “Unlimited” alternatives.
