Key takeaways
Brunei Darussalam is a small, wealthy sultanate with two mobile carriers, DST and Progresif, delivering strong 4G LTE coverage across the country. The compact size means connectivity is reliable in virtually all urban areas and main roads. A Roamix Brunei eSIM connects you to the strongest network on arrival at Brunei International Airport with no roaming fees. The exception is deep jungle in Ulu Temburong, where signal disappears. Budget 3 to 5 GB for a typical week-long visit.
- DST is the market leader with the best 5G rollout and national coverage in Brunei.
- A Roamix eSIM activates on arrival at Brunei International Airport and avoids expensive carrier roaming.
- Brunei is one of Asia's most affordable countries to visit, with free admission at many palaces and mosques.
- Alcohol is banned in Brunei; the country is conservative and Islamic social codes apply to dress and behaviour.
- Ulu Temburong National Park is off-grid deep in the jungle, so download maps and book permits in Bandar Seri Begawan.
Best way to get data in Brunei Darussalam
For most visitors to Brunei, a Roamix eSIM is the most convenient option, connecting you instantly on arrival and costing a fraction of home carrier roaming rates.

|---|---|---|
| Roamix eSIMRecommended | Best for: Most travellers | Instant activation on arrival, connects to DST or Progresif and avoids expensive roaming from home carriers. |
| Local physical SIM | Best for: Extended stays needing a local number | DST and Progresif SIMs are sold at the airport arrivals hall. No passport registration required for tourist SIMs. |
| Pocket wifi | Best for: Groups sharing one connection | Available for rental in BSB. Another device to carry and charge. |

Both DST and Progresif offer 4G LTE nationwide across the country's compact territory. DST leads on 5G deployment in the capital. A Roamix Brunei eSIM connects to the strongest available network the moment you land.

Deep jungle sections of Ulu Temburong National Park have no signal on any carrier. The park is accessible only by longboat, and camp facilities rely on limited wifi. Download all maps and park information before boarding the longboat in Bangar.
