Brunei: Mobile Coverage & Carriers
ESIMBYCOUNTRY at checkout · See all codes →Brunei's mobile market is served by three carriers: imagine (operating under UNN), DST, and Progresif. All three networks have commercially launched 3G and 4G/LTE services. 5G services have also been commercially launched in the country, though specific deployment details remain limited in available sources.
Roaming eSIMs in Brunei typically operate on LTE bands B3 (1800 MHz) and B8 (900 MHz), as well as the 5G band n78 (3.5 GHz). Some local carriers issue eSIMs to their customers, though availability and rollout status vary by provider and should be confirmed directly with individual operators. Given the limited publicly available information on certain aspects of Brunei's mobile infrastructure, travelers and users are advised to verify current network capabilities with their chosen carrier.
