Can I use apps such as Google, YouTube and KakaoTalk freely in Brunei?

Yes, Brunei has no particular restrictions on internet access. You can use the apps you used in Korea, such as Google, YouTube, KakaoTalk and Instagram, just as they are. You can use them freely without a VPN.

Will I need a power adapter when travelling in Brunei?

Yes, Brunei uses British-style Type G sockets. They are different from Korea's Type C/F plugs, so be sure to bring an adapter. The voltage is 240V, which differs from Korea's (220V), so it pays to check the supported voltage of your electronic devices in advance as well.

Do I need a visa to enter Brunei?

Korean passport holders can enter Brunei visa-free. You can stay for up to 30 days. However, your passport must have at least 6 months of validity remaining, so be sure to check before departure.

Can I buy alcohol in Brunei? Is there anything to be careful about while travelling?

Brunei is an Islamic country, and drinking in public places and the sale of alcohol are prohibited, even for non-Muslim foreigners. Restaurants do not serve alcoholic drinks either. You are allowed to bring in a small amount of alcohol when you enter, but it is good to know in advance that you cannot buy it locally. As for dress, you must wear long clothing when visiting a mosque.

How do I visit Brunei's water village (Kampong Ayer)?

Kampong Ayer is the world's largest water village, with a unique landscape of houses packed closely together on the Brunei River. You can get there by small boat (water taxi) from the riverbank. Google Maps makes it easy to find where the jetties are and how to board a boat, so Yeohaengyusim eSIM data is a big help.

Does eSIM work in Brunei?

Brunei supports eSIM, and plans start from ₩13,373. Install it with the QR code you receive after buying, then just turn on data roaming after you arrive and you are connected straight away. There is no need to swap your SIM.

Travel eSIM or carrier roaming: which is cheaper for a trip to Brunei?

For a short trip or light data use, a travel eSIM is usually cheaper. Unlimited roaming from Korean carriers costs about ₩11,000–₩15,000 a day, but with an eSIM you can buy just the days of data you need in advance. For a short trip for one or two people, an eSIM has a big advantage; for a family or very heavy data use, compare carrier unlimited roaming too.

Which carrier network does a Brunei eSIM use?

In Brunei it connects automatically to local carrier networks such as DST · Progresif · imagine (4G/LTE, 5G where supported). Population coverage is about 92%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I keep using my Korean number while travelling in Brunei?

Yes. The eSIM works as a data-only second line, so your Korean SIM and number stay as they are. Use the Yeohaengyusim eSIM for data only, and keep receiving calls, texts and KakaoTalk on your Korean number.

Can I add to or extend my Brunei eSIM plan?

Yes. When you use up your data or the plan period ends, you can buy a new plan at any time. Keep using the eSIM profile you already installed; there is no need to install it again, so you carry on without interruption.

Can I use tethering (hotspot) in Brunei?

Yes. In Brunei you can share your eSIM data with other devices such as a laptop or tablet by tethering (hotspot). Shared data also comes out of your plan allowance, so if you tether a lot we recommend choosing a little more data.

Do I set up the eSIM before I leave or after I arrive?

We recommend installing it (registering the QR code) before you leave, while you have Wi-Fi. Data starts when you turn on data roaming after you arrive in Brunei. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

Brunei, a small kingdom in the north of the island of Borneo, wins travellers' hearts with its splendid golden mosques, dense tropical rainforest and an atmosphere that is simple yet dignified. The grand dome of the Omar Ali Saifuddien Mosque glittering over the river looks like a scene from a fairy tale. It is small, but it is very safe and prices are affordable, so it suits Korean travellers who want a quiet trip especially well. From tasting local food at the bustling waterfront night market to the special experience of meeting orangutans in Ulu Belait National Park, Brunei is a hidden-gem destination you can enjoy to the full even on a short schedule. With just one Yeohaengyusim eSIM, you can use Google Maps, translation apps and social media without interruption right after landing at the airport, so even unfamiliar Brunei is much easier to get around.

Why you need a travel eSIM for Brunei

Because Brunei does not get many visitors, SIM sales booths at the airport are limited. To get a SIM locally, you have to go to a carrier's agent in town yourself, and wandering around an unfamiliar city looking for a SIM shop is a real hassle. With a Yeohaengyusim eSIM, you install it in Korea in advance, and it links up automatically with the DST or Progresif network the moment you reach Brunei's Bandar Seri Begawan International Airport. You don't need to take your existing SIM out and put another in: a single QR code scan takes care of everything. Brunei is a small country, so you will not travel far, but 4G/LTE network coverage reaches 92%, so you can use fast, stable data at the main tourist sites and in town. To do everything on one smartphone, from finding mosque locations and booking water taxis to the water village to looking up rainforest trekking information, a stable data connection is a must. Explore every corner of Brunei as much as you like, without worrying about roaming charges.
