What a Muara Mobile eSIM costs
The cheapest published plan on the Brunei travel eSIM is $7.00 for 1 GB valid 7 days. A 2 GB / 15 day plan is $11.25, a 3 GB / 30 day plan is $15.30, a 5 GB / 30 day plan is $22.95, and a 10 GB / 30 day plan is $41.65. Unlimited plans are listed on the same product at $19.50 for 3 days, $28.50 for 5 days, $35.00 for 7 days, and $42.50 for 10 days. Buy the size that matches the trip, not a larger plan “just in case”.
Network
The plan is sold under the operator name Muara Mobile and the supported country is Brunei. The product page publishes the speed as 5G. That is the figure to plan around. A 5G label still depends on the mast, the handset, and the carrier Fair Usage Policy. Where 5G is not available, the phone drops to a slower band. Brunei is a small country, so one national plan covers Bandar Seri Begawan, the coast, and the road toward the Malaysian border. It does not cover Malaysia.
How much data you actually need
Maps, chat, and boarding passes sit inside 1 GB for a short city stay. Photos and short video push a week toward 2 or 3 GB. A month of hotel Wi-Fi plus mobile backup is the 3 GB, 5 GB, or 10 GB / 30 day plan. Hotspot use burns the allowance faster than the phone alone.
Unlimited data
Unlimited Muara Mobile plans are on the product page, from $19.50 for 3 days up to $42.50 for 10 days. Each is a separate SKU from the 1 GB plan. Read that line before you add it to the cart. Unlimited still sits under a Fair Usage Policy, so a hotspot left on all day can be slowed.
Dual SIM
Keep your home SIM for calls and bank texts. Turn on data roaming only for the Muara Mobile line. iPhone: Settings, Mobile Data, pick the travel line. Android: Settings, Network, SIMs, set mobile data to the travel eSIM. Do this before you leave the airport Wi-Fi.
Arrival and transit
Most visitors land at Brunei International Airport (BWN) in Bandar Seri Begawan. Install the eSIM on hotel or home Wi-Fi before the flight, then switch the data line on after you clear arrivals. You do not need a local shop or a passport photo for this plan.
Install
- Buy the plan and open the QR code in the order email while you still have Wi-Fi.
- On the phone, add an eSIM and scan that code. Label the line “Brunei”.
- After landing, set mobile data to that line and leave your home number on for texts.
Phone compatibility
The phone must be carrier-unlocked and eSIM-capable. iPhone XS and later, and recent Samsung Galaxy and Google Pixel models, qualify. A locked handset will not take the QR code. Check the lock status with your home carrier before you pay.
FAQ
Q1: How much is the cheapest Brunei eSIM?
$7.00 for 1 GB, valid 7 days, on the Muara Mobile plan.
Q2: Which operator is on the plan?
Muara Mobile. The supported country is Brunei.
Q3: Does it include calls and SMS?
No. It is a data plan. Keep your home SIM for calls and one-time passwords.
Q4: Is it 5G?
Yes. The product page lists the speed as 5G. Real speed still depends on coverage and the Fair Usage Policy, and the phone falls back where 5G is not on the mast.
Q5: Can I install it after I land?
Yes, if you can reach Wi-Fi. Installing before the flight is simpler, because the QR download needs a connection.
Q6: Will it work in Malaysia?
No. This plan is for Brunei. Buy a separate plan if the trip continues across the border.
Q7: Is there an unlimited option?
Yes. Unlimited plans are listed separately on the same product page, from $19.50 for 3 days.
Q8: Can I share it as a hotspot?
Yes, within the data allowance. Hotspot traffic counts against the same gigabytes, and heavy sharing can hit the Fair Usage Policy.
Q9: What if the QR code fails?
Use the manual activation code in the same email. The phone still has to be unlocked.
Q10: When were these prices checked?
September 2026, against the published variation prices on travelydata.com.
Bottom line
For a week in Brunei, the $7.00 / 1 GB Muara Mobile plan is the one to start with. Step up to 2 GB or 3 GB if you will be off hotel Wi-Fi most of the day. The published speed is 5G.
