Your Brunei eSIM in two questions
Which Brunei eSIM plan do I need?
In Brunei, your trip length and how much you use your phone decide the plan, so match both to one of these.
- A three-day city break in Bandar Seri Begawan: for standard use, with social media, music and some video, pick 3 GB for 15 days.
- A fortnight touring Brunei: with standard use, moving between Kuala Belait, Tutong and Temburong, pick 10 GB for 30 days.
- A month-long stay: with standard use over 30 days, pick 20 GB for 30 days, so your data lasts as long as your visit.
- A trip that takes in another country: the Global bundle covers 127 countries, so one eSIM can carry you across the border.
Most plans can be topped up, so extra days are an easy fix.

These eSIMs cover Brunei and more countries on one plan.
Will my eSIM have signal in Brunei?
Your eSIM joins the DS network in Brunei, and DS runs on 5G. Your phone picks DS by itself, so there's nothing to set up once you land. Your data reaches the internet through Singapore, a normal setup for travel eSIMs. Our IP address guide explains what that means for sites that check where you are.
Daily plans are a little different. Once you use up that day's allowance, your speed slows to the fair use speed, so pick a size that covers your busiest day. Light plans suit messages and maps, while longer trips with video need more.
How much data do you need in Brunei?
Light: maps, messages, email (about 0.25 GB a day). Standard: plus social, music, some video (about 0.7 GB a day). Heavy: plus streaming, video calls, hotspot (about 1.8 GB a day).

- Staying in touch: WhatsApp is the messaging app to have ready, and your home number stays on for calls and texts. Keep both sorted with WhatsApp and your home number.
- Your network: Your eSIM runs on DS, which carries 5G. Check that your phone supports 5G before you buy.
- Data for your days: Light use, such as maps and messages, is about 0.25 GB a day, or about 3.5 GB over two weeks. Standard use, with social media and some video, is about 0.7 GB a day, or about 9.8 GB over two weeks. Most plans can be topped up if you need more before you fly home.
Brunei eSIM questions
How much is an eSIM for Brunei?
Brunei eSIMs start at £4.99 for 500 MB a day over 1 day. A 3 GB plan for 30 days costs £18.99. Prices include any taxes and show in pounds, euros or dollars.
Which networks does the Brunei eSIM use?
Your eSIM connects to DS in Brunei, with 5G where the network has it. Your phone picks the strongest signal automatically.
When does my Brunei eSIM start?
Most plans start the moment your eSIM first connects to a network in Brunei, so you can buy and install it at home before you fly. Install it within 180 days of buying.
Can I top up my Brunei eSIM?
Yes. Most Brunei plans can be topped up from your eSIM page in two taps, with no new QR code. The plan table on this page shows which ones.
Why does my IP address show another country?
Brunei plans route your data through Singapore, a normal setup for travel eSIMs. Websites and apps may show that country's content; your speed and coverage in Brunei are not affected.
Does it come with a phone number?
Every eSIMology plan is data only. Keep your own SIM switched on for calls and texts, and use WhatsApp, FaceTime or any calling app over your eSIM's data.
What if my plans change?
Cancel an eSIM you haven't installed within 30 days for a full refund to your card, in two taps from your eSIM page.
Does WhatsApp work with an eSIM in Brunei?
WhatsApp is the app to have ready in Brunei, and your eSIM's mobile data carries your messages, photos and group chats. Video files use data quickly, so keep an eye on your allowance if you send a lot of them.
Is there 5G in Brunei?
Yes. DS, the network your eSIM runs on in Brunei, offers 5G, so check that your phone supports it before you fly into Brunei International (BWN).
Can one eSIM cover Brunei and other countries on my trip?
Yes. A Global eSIM covers 127 countries, and Brunei is one of them, so you can keep one eSIM for a longer trip. Pick it once your route goes beyond Brunei's borders.
Can I share my eSIM data as a hotspot in Brunei?
Sharing your connection with a laptop counts as heavy use in Brunei, so it runs through data much faster than messages and maps. Choose a plan with room for it, especially if your laptop works from Bandar Seri Begawan all day.
Can I buy an eSIM for just one day in Brunei?
Yes. Daily plans start at one day and run up to 30, so a short stop at Brunei International (BWN) only needs the days you're in the country.
