Astaroam eSIM Data Plans for Brunei

Astaroam does not provide a true unlimited data eSIM for Brunei. The plans labeled “Unlimited” are limited to 3 GB per day and after that amount the speed is throttled to 1 000 kbps.

If an unlimited plan is not required, Astaroam offers fixed‑data options such as 10 GB for 30 days or 5 GB for 30 days. These bundles can be more economical for travelers who do not need a very large data allotment before the plan expires.

Astaroam does not provide an eSIM plan for Brunei that includes a local phone number or SMS capability. Travelers who need a voice or text service will need to rely on data‑only plans and use VoIP applications such as WhatsApp, Telegram, or iMessage. These apps generally work over the data connection, but because some destinations may block or restrict access to specific VoIP services, it is advisable to verify that the apps you rely on are accessible in Brunei before purchasing an Astaroam eSIM.

Astaroam offers nine single‑country data plans for Brunei, with no multi‑country options. The plans are split into three daily‑data cap variants and six fixed‑data cap variants. Prices range between $3.65 and $33.40, data caps cover 1 GB to 10 GB, and validity periods span from 3 to 30 days. Some of the plans allow tethering and include a reduced speed limit of 1000 kbps.
