Power & Connectivity (SIM)

Brunei uses 240V / 50Hz with Type G sockets (the British three rectangular pins). Bring a Type G adapter; travellers from 100–120V countries need a converter for devices that are not dual-voltage.

The main operators are imagine (formerly DST) and Progresif, both offering 4G and expanding coverage. Prepaid SIMs are sold at the airport and operator shops. Registration requires your passport, so bring it when buying a SIM.

eSIM support is progressing in Brunei, and travel eSIM plans covering the country can be bought online before arrival and installed in minutes, with no physical SIM or shop visit. Check availability with your chosen provider before you go.

Wi-Fi is common in hotels and shopping malls in Bandar Seri Begawan, and many cafés offer it too. Quality is generally reliable in urban areas. Use a VPN on public networks for sensitive tasks like banking.

The internet is generally usable in Brunei, and common apps such as messaging, social media and maps work normally. Some content deemed contrary to public morals may be regulated, so browsing habits that respect local norms are advisable.

Handy apps for Brunei include the Dart ride-hailing app for taxis, plus maps and translation apps. WhatsApp is widely used for messaging. Download and set up apps while you have a stable connection.

Brunei's country code is +673. App-based calls (WhatsApp, FaceTime and similar) are common and convenient. Save numbers in full +673 format so they work from any network or when calling from abroad.
