Budget 3 to 5 GB for a typical week-long visit.

Get your Brunei Darussalam eSIMMobile Networks in Brunei Darussalam
Brunei has two main operators, DST Communications and Progresif, with a third legacy network under the Imagine brand. 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.
DST and Progresif use standard Southeast Asian LTE bands compatible with most modern unlocked smartphones from iPhone XS onward.
Data Usage Guide
Brunei's compact size makes data use moderate. Most activities are in or near the capital, with offline preparation needed only for Ulu Temburong jungle treks.
