Voyasim does not provide an unlimited data eSIM plan for Brunei. All of its offerings for the country are fixed data plans with a hard cap on the amount of high‑speed data that can be used.
The available options include a 20GB plan valid for 30 days priced at $71.30 USD, a 20GB plan valid for 90 days priced at $94.20 USD, a 10GB plan valid for 30 days priced at $39.30 USD, and a 5GB plan valid for 30 days priced at $35.20 USD. These fixed data plans may be more cost‑effective for most travelers unless they require an extremely high volume of data.
