Ubigi eSIM Data Plans for Brunei

Ubigi does not provide an unlimited data eSIM plan for Brunei. The available plans have fixed data caps, with the largest offering 60GB for 30 days under the “BEST WORLD” or “WORLD” names. For travelers who need more data, Ubigi also offers 50GB plans that last 120 or 180 days and a 30GB plan for 15 days. While these fixed‑data packages are cheaper for most users, an unlimited plan is currently not available through Ubigi in Brunei.

Ubigi does not offer an eSIM plan for Brunei that includes a phone number or SMS capability. Only data‑only eSIMs are available. Travelers can still stay connected by using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging.

Ubigi has four single‑country data plans and twenty‑four multi‑country plans that include Brunei. The plans range in price from roughly $2 to $210 and offer data volumes from 500 MB to 60 GB. Some options use a daily data cap, meaning the allowance refreshes each day, while most plans are fixed‑amount plans that let users consume a set quantity of data until the plan expires.
