MobileSIM eSIM Data Plans for Brunei

MobileSIM does not currently provide an unlimited‑data eSIM plan for Brunei. Travelers who need high‑capacity data will need to purchase one of the fixed‑data options instead.

Fixed‑data plans are available for Brunei, including a 20 GB plan valid for 365 days priced at $69.00 USD, a 10 GB plan valid for 180 days priced at $59.00 USD, as well as local Brunei‑only plans of 5 GB for 30 days at $35.00 USD and 3 GB for 30 days at $20.00 USD. These higher‑cap plans may offer a better cost‑to‑data ratio for most users, while an unlimited plan may be preferable only for very 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.

MobileSIM provides a range of eSIM data plans for Brunei. In total there are four single‑country plans and seven multi‑country options. The plans cover a broad spectrum of data allowances, from as little as 200 MB up to 20 GB, with prices spanning roughly $1.50 to $69.00 USD. The validity period of the plans varies between seven and 365 days, enabling both short‑term travelers and longer‑staying visitors to choose a package that fits their needs.
