nextSIM offers plans in Brunei that are marketed with “Unlimited” in the name, but the data cap is only 1GB or 2GB per day and once the limit is reached the speed drops to 512kbps or 2000kbps, respectively. These plans are not truly unlimited high‑speed data; they provide a fixed amount of data before throttling occurs.
For travelers who want unlimited high‑speed data without a cap, nextSIM offers fixed‑data plans such as the 20GB 30‑Day plan priced at $163.56 USD and the 10GB 30‑Day plan priced at $91.03 USD. Other larger data options include the 5GB 30‑Day plan at $49.59 USD and the 3GB 30‑Day plan at $30.05 USD. These fixed‑data plans provide the full amount of data at the advertised speeds throughout their validity, making them a more cost‑effective choice for heavy data users.
