abesteSIM eSIM Data Plans for Brunei

abesteSIM does not provide a truly unlimited data eSIM for Brunei. The only plan that carries “Unlimited” in its name offers 1 GB of high‑speed data per day for a single day, after which the speed is reduced to 5000 kbps. This is a fixed‑data plan rather than an unlimited one.

Travelers who need more data can choose from abesteSIM’s fixed data plans, such as the 50 GB bundles that are valid for 5, 7, 10, or 15 days. These plans give a large amount of high‑speed data and may be more cost‑effective for most users, unless an extremely heavy data consumer requires a truly unlimited option.

abesteSIM does not offer any Brunei eSIM plan that includes a phone number or SMS capability. The provider only offers data‑only eSIMs for travellers visiting Brunei.

Because a phone number or SMS is not supplied, users can still place and receive calls or send messages through popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to certain apps or VoIP services, so it is advisable to confirm beforehand that the applications you rely on are usable in Brunei before purchasing an abesteSIM data‑only plan.

abesteSIM offers 85 single‑country plans for Brunei, with no multi‑country options available. The plans span a price range from $1.48 to $226.69 and a data cap range from 500 MB up to 50 GB. Users can choose between daily data cap plans—48 in total—or fixed data cap plans—37 in total—depending on their usage needs. The plans also allow tethering and may include reduced speed options of 128 kbps or 5000 kbps.
