MobileSIM eSIM Data Plans for Brunei

MobileSIM does not provide a truly unlimited data eSIM for Brunei. The only plan that carries “Unlimited” in its name offers a data cap of 3 GB per day and, after reaching that limit, the speed drops to 1000 kbps. Travelers who require a larger data allowance may choose from MobileSIM’s fixed plans. For example, a 20 GB plan is available for 30 days at $66.00 USD and a 10 GB plan is available for 30 days at $49.00 USD. These fixed‑data options can be more cost‑effective for users who are not extremely heavy data consumers.

MobileSIM does not offer a Brunei eSIM that includes a phone number or SMS capability. The provider only sells data‑only eSIM plans for Brunei, so travelers must use internet‑based VoIP services such as WhatsApp, Telegram, or iMessage for voice and messaging instead of a traditional phone number.

For Brunei, MobileSIM provides 6 single‑country data plans and 10 multi‑country plans. The available plans range from about $2.30 to $165.00 and cover data caps between 200 MB and 60 GB. Plans are split into fixed‑data‑cap options, where a set amount of data is usable over the entire validity period, and a daily‑data‑cap option, which offers a small data allowance each day of the plan.
