Travel guide: Brunei
Brunei is a small sultanate on Borneo that, thanks to its oil reserves, ranks among the wealthiest countries in the world – yet remains untouched by mass tourism. Instead of crowded attractions, you'll find golden mosques, a vast water village and pristine rainforest. The capital, Bandar Seri Begawan, may seem quiet at first glance, but it reveals itself as a lively blend of tradition and modernity. If you like to travel off the beaten path, you'll discover one of the safest and cleanest corners of Southeast Asia.

Mobile internet in Brunei
Mobile networks in Brunei are operated by the state provider UNN. In towns and along main roads you'll get stable 4G, and often even 5G in Bandar Seri Begawan and the surrounding area. In remote areas such as Ulu Temburong National Park, however, reception can be weak – it's worth saving maps and content offline in advance.
Public Wi-Fi is mainly found in hotels, cafés and shopping centres. Outside the city it's scarce and often slow. With an eSIM you're independent from the first minute, without having to worry about local SIM cards or registrations.
Brunei filters certain internet content, but for everyday travel use such as navigation, translation and social media the network is reliable. The local ride-hailing app Dart is handy for getting around cheaply in the city. For trips into nature, offline maps and a translator with a download function are recommended.
Highlights in Brunei
Jame' Asr Hassanil Bolkiah Mosque
Brunei's largest mosque impresses with 29 golden domes and intricate ornaments. It's located a little outside the centre and is a popular photo spot, especially in the late afternoon.
Mangrove tour on the Brunei River
On a boat tour through the mangrove forests you may be lucky enough to spot proboscis monkeys, crocodiles and many bird species. In the evening, tours are often offered where you can see fireflies.
Istana Nurul Iman
The Sultan's palace is considered the largest residential palace in the world. It's normally not accessible, but during Hari Raya Aidilfitri it opens its doors to visitors for a few days.
Gadong Night Market
In the evening the market turns into a paradise for street food lovers. Here you'll find cheap local dishes such as nasi katok, grilled fish and sweet snacks.
Kampong Ayer – the water village
The historic stilt settlement on the Brunei River has been inhabited for centuries and has its own schools, mosques and shops. You can take a water taxi through the canals and experience the residents' daily life.
Ulu Temburong National Park
The pristine rainforest is only reachable by boat and offers enormous biodiversity. From the canopy walkway you get a breathtaking view over the green treetops.
Practical travel tips
- Use the ride-hailing app Dart for trips in the city; it's reliable and often cheaper than taxis. For excursions further afield, a rental car is recommended – remember to drive on the left.
- Visit mosques early in the morning or late in the afternoon, when the light is best for photos and temperatures are more pleasant.
- Try local specialities such as nasi katok, ambuyat and grilled fish – most authentic at Gadong Night Market.
- Drink plenty of water because of the tropical climate; tap water is considered safe, but in remote areas bottled water is the better choice.
- Learn a few words of Malay such as 'terima kasih' (thank you) and 'selamat pagi' (good morning) – locals appreciate it.
- Show respect for the Sultan and the royal family; any criticism is taboo and can have serious consequences.
Do’s
- Take off your shoes before entering mosques and private homes – look out for signs.
- Use your right hand when eating and handing over objects; the left is considered unclean.
- Greet locals with a friendly 'Assalamualaikum' – it's seen as respectful.
- Dress conservatively in public: shoulders and knees should be covered, especially outside tourist areas.
- Always ask permission before photographing people.
Don’ts
- Don't drink alcohol in public – consumption is only allowed in private spaces for non-Muslims.
- Don't eat or drink in public during Ramadan daylight hours.
- Don't show public displays of affection such as kissing or holding hands – it's considered inappropriate.
- Don't photograph military or government buildings – it can get you into trouble.
- Avoid criticising the Sultan or the royal family – it's a punishable offence.

Brunei eSIM – frequently asked questions
Which Brunei eSIM plan do I need?
That depends on how much data you use: for navigation, messaging and occasional browsing 1–3 GB per week is usually enough; for social media, video calls or hotspot rather 5 GB or more. The plans cost between €4.99 and €54.99.
When does the validity of my eSIM start?
Validity only starts when the eSIM connects to a network at your destination for the first time. So you can safely install it before your trip.
Will my normal phone number stay reachable?
Yes. This is a data-only eSIM installed in addition to your SIM card. Calls and SMS still use your normal number – mind your provider’s roaming prices.
Does the eSIM work with my phone?
Your phone must support eSIM and be carrier-unlocked. This includes all iPhones from XS/XR, Samsung Galaxy from S20 and Google Pixel from 3. See “Compatible devices” for the full list.
How do I set up the eSIM?
After purchase you receive a QR code by email. Scan it in your phone’s mobile network settings, select the eSIM for mobile data and switch on data roaming for the eSIM at your destination.
Do I need to set an APN?
No. The access point (APN) is set automatically for all Brunei eSIM plans.
Do WhatsApp, Google and Instagram work with the eSIM?
In most Asian countries, yes, without restrictions. In some countries (e.g. China) certain services are blocked on local networks; travel eSIMs usually route data abroad, so these services generally remain available. We cannot guarantee this, though.
Is an eSIM cheaper than a SIM card at the airport?
Often, yes – mainly because you do not lose time at the airport, do not need to show your passport and know the exact price in advance. Your normal SIM also stays in your phone.
