Lotso Travel does not provide a truly unlimited data eSIM for Brunei. The plans that carry “Unlimited” in their name all offer a fixed amount of high‑speed data, after which the speed drops to a reduced rate of 384 kbps (or 5.1 Mbps for some). For example, the Brunei 50GB eSIM plans supply 50GB of full‑speed data for 5, 10, 15, or 30 days before throttling, and the Brunei 30GB eSIM plans deliver 30GB of full‑speed data for 15 or 30 days before the speed reduction.
If a traveler needs a large amount of data, fixed‑data plans such as the Brunei 50GB eSIM (5‑30 days) or the Brunei 30GB eSIM (15‑30 days) are suitable alternatives. These plans can be more cost‑effective for users who need high‑speed data without paying for excessive bandwidth, and they avoid the throttling that occurs after the data allowance is consumed.
