Installation

How to set up the eSIM for Brunei

iOS installation (iPhone)

Open Settings > Cellular > Add eSIM
Select "Use QR Code"
Scan the QR code from your Nomad confirmation email
Label the plan (e.g., "Brunei Travel")
Set as cellular data line (not your default for calls)
Do NOT enable data roaming yet
Confirm the plan appears under Settings > Cellular

iOS 18: the "Add eSIM" option appears under Settings > Cellular > Add Cellular Plan. iOS 17 and earlier: Settings > Cellular > Add eSIM.

Android installation (Google Pixel)

Open Settings > Network & Internet > Add eSIM
Select "Download a SIM instead" then scan
Scan the QR code from your Nomad confirmation email
Name the profile (e.g., "Brunei Data")
Set as mobile data SIM
Do NOT enable data roaming yet
Verify the plan in SIM manager

Manual installation (if QR fails)

If the QR code does not scan, use manual entry:

Go to Settings > Cellular > Add eSIM
Select "Enter Details Manually"
Enter the SM-DP+ address from your provider email
Enter the activation code
Complete the setup as with the QR method

Use manual entry when: camera cannot read the QR code, the email was forwarded without the image, or you are installing on a second device.

Configuration

DST APN settings for eSIM

Automatic APN configuration

Most eSIM profiles auto-configure APN settings for DST's network. After installation, verify the APN is set correctly:

iPhone: Settings > Cellular > Cellular Data Options > Cellular Data Network
Android: Settings > Network & Internet > SIMs > (travel eSIM) > Access Point Names

A correctly configured APN shows the carrier name and data type. If the APN field is blank, your phone will attempt to auto-fill on first connection.

Manual APN entry

If auto-configuration fails (rare, typically older Android devices), enter APN settings manually. Check your provider's confirmation email for the exact values. Common fields:

APN configuration fields
Field	Value
APN Name	From provider email
APN	Provider-specific value
Authentication	None (most providers)
APN Protocol	IPv4/IPv6

Provider-specific APN values override DST's carrier defaults. Always use the values from your provider, not generic carrier APNs.

Verification

Is your Brunei eSIM connected

Signal and network verification

Check your status bar: the carrier name should show DSTor a roaming indicator. Signal bars confirm connection strength. Go to Settings > Cellular to verify data usage is counting on the travel eSIM line.

"DST" or roaming icon: Connected and working
"Searching...": Still connecting, wait 2-3 minutes
"No Service": Data roaming is off or wrong SIM line selected

Speed test

Run fast.com or Speedtest.net to verify your connection speed. Expected speeds: 4G LTE (LTE typically 20-80 Mbps, 5G 100-500 Mbps where available). Speeds vary by location: airports and city centers are fastest, rural areas slower.

Verifying data roaming is active

Go to Settings > Cellular > (travel eSIM) > Data Roaming: ON. Test by opening any website in your browser. If it loads, roaming is active. If not, toggle data roaming off and back on, then restart your phone.

Dual-SIM verification

Confirm your home SIM still receives calls and texts. Confirm the travel eSIM handles all data traffic. Test: send yourself a text message to your home number. Then load a webpage. Both should work simultaneously. If data routes through the home SIM instead, switch your cellular data line to the travel eSIM.

Airport Guide

Arriving at Brunei's main airport with your eSIM

Before boarding

The night before your flight, open Settings, add a new eSIM, and scan the QR code from your order email. Your home WiFi provides the clean connection the download needs. After it installs, switch the Brunei profile to off. Leave it dormant until wheels touch the runway. DST picks up the signal within 60-90 seconds of your phone leaving airplane mode.

During the flight

Keep airplane mode on during the flight. Confirm your Brunei eSIM is set as the designated data line under Settings before you descend. Your home SIM stays active for calls and SMS verification codes. If you have not installed a VPN yet, do it now over in-flight WiFi — Brunei restricts VoIP services, and downloading a VPN app after landing may not work.

After landing

Once the seatbelt sign is off, disable airplane mode and enable the Brunei eSIM. DST registers the profile in 60-90 seconds. You have maps, messaging, and ride-share access before the cabin door opens. SIM counter availability at Brunei's main airport varies by terminal and time of day. Your eSIM eliminates that variable entirely.

Leaving the airport

Your eSIM is working. Open your ride-share app and request a pickup while you wait at baggage claim. By the time your bag arrives, the car is already en route. No WiFi hunting, no SIM counter, no wasted minutes. Brunei's emergency number is 993/995/991 — it works without data, but having your eSIM active means you can also share GPS coordinates with emergency services.

Device Setup

Device-specific instructions for Brunei

iPhone (iOS 17+)

Open Settings > Cellular > Add eSIM > Use QR Code.
Point the camera at the QR code from your provider's email. The profile downloads in 5-15 seconds on stable WiFi.
Tap "Add Cellular Plan" when prompted. Label the plan "Brunei Data" to distinguish it from your home line.
Go to Settings > Cellular > Cellular Data and select the Brunei eSIM as your active data line.
Turn on Data Roaming for the Brunei line only: Settings > Cellular > [Brunei Data] > Data Roaming > On.
After landing at Brunei's main airport, toggle the eSIM on. DST registers your profile in 60-90 seconds. APN settings auto-configure for most Brunei eSIM plans on DST's network.
Verify: open Safari and load any webpage. If the page renders, your Brunei data is active at 4G LTE speeds.

Carrier confirmation: Your status bar should display "DST" or "Progresif" with 4G signal within 60-90 seconds. On iPhone, check Settings > Cellular — the Brunei line shows "DST" under Network. The "4G" indicator confirms your connection type.

Note: If the carrier field shows "No Service" after 2 minutes, go to Settings > Cellular > Network Selection, turn off Automatic, wait 10 seconds, then turn it back on. If DST does not appear in the list, restart your iPhone (hold Side + Volume Down for 3 seconds, slide to power off, wait 30 seconds, power on).

Enable Data Roaming: Settings > Connections > Mobile Networks > Data Roaming > On (for the travel SIM only).
After landing at Brunei's main airport, enable the eSIM. DST's 4G network registers within 60-90 seconds. APN settings load automatically for most Brunei eSIM plans on DST's network.
Verify: open Chrome and load any page. Data flowing confirms your Brunei eSIM is active.

Carrier confirmation: Your status bar should display "DST" or "Progresif" with 4G signal within 60-90 seconds. On Samsung, check Settings > Connections > SIM Manager — the travel SIM shows "DST" as the connected network. The connection type shows as "4G".

Note: If "No Service" persists after 2 minutes, go to Settings > Connections > Mobile Networks > Network Operators, switch from Automatic to Manual, wait for the scan to complete, then select DST. If the carrier does not appear, restart the device: hold Power + Volume Down until the restart menu appears.

Google Pixel (Android 14+)

Open Settings > Network & Internet > SIMs > Add SIM > Download SIM.
Scan the QR code from your eSIM provider's email. The profile downloads in under 15 seconds.
Confirm the download and label the SIM "Brunei Data" for identification.
Set as mobile data SIM: Settings > Network & Internet > SIMs > Brunei Data > Use for mobile data.
Enable roaming: Settings > Network & Internet > SIMs > Brunei Data > Roaming > On.
After landing at Brunei's main airport, enable the profile. DST connects within 60-90 seconds. APN settings self-configure on Pixel devices for most Brunei plans.
Open Chrome and load any page to verify data connectivity on DST's 4G network.

Carrier confirmation: Your status bar should display "DST" or "Progresif" with 4G signal within 60-90 seconds. On Pixel, check Settings > Network & Internet > SIMs — the travel SIM displays "DST" as the active network.

Note: If the signal does not register within 2 minutes, go to Settings > Network & Internet > SIMs > Brunei Data > Advanced > Choose network, switch to Manual, let the scan run, and select DST. If it fails, reset network settings under Settings > System > Reset options > Reset Mobile, WiFi & Bluetooth.

Carrier Config

Carrier troubleshooting for Brunei

DST

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "DST" from the list. The phone locks onto DST's 4G band and data resumes within 30 seconds.

Expected speed: Fastest 4G speeds in Brunei's urban areas

Common issue: Some eSIM plans routed through DST require data roaming to be enabled on the travel SIM line specifically. Leaving it off is the most common reason travelers report zero signal after landing in Brunei. Check under Settings > Cellular > [Travel eSIM] > Data Roaming.

Resolution: Toggle airplane mode on for 15 seconds, then off. This forces a fresh network scan without a full restart. DST should appear in your carrier field within 60 seconds. If it does not, use manual network selection to find and choose DST directly.

Progresif

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "Progresif" from the list. The phone locks onto Progresif's 4G band and data resumes within 30 seconds.

Expected speed: Reliable 4G coverage across Brunei's main cities

Common issue: Progresif may show a signal bar but no data if the APN was not auto-configured. This happens on roughly 10-15% of Brunei eSIM activations. Contact your eSIM provider for the correct APN string.

Resolution: Reset network settings: Settings > General > Transfer or Reset > Reset Network Settings (iPhone) or Settings > General Management > Reset > Reset Network Settings (Samsung). This clears saved WiFi passwords but resolves most Progresif registration failures. Re-enable the Brunei eSIM after the reset completes.

Dual SIM

Set up dual SIM before landing in Brunei

Data line setup

Configure the Brunei eSIM as primary data: Settings > Cellular > Cellular Data. DST provides 4G coverage across Brunei's main areas. Turn off "Allow Cellular Data Switching" so the phone never reverts to your home carrier for data. That single toggle prevents the most common cause of unexpected roaming bills during travel.

Calls and SMS

Keep your home SIM active for incoming calls and SMS. Your phone number stays reachable, and two-factor authentication codes from banks and services arrive normally via text. Outgoing calls use your home number unless you manually switch to the Brunei line. For voice calls over data — WhatsApp, FaceTime, Telegram — those route through the eSIM's data connection on DST. Note: Brunei restricts VoIP services. Install a VPN before departure to use voice-over-data apps.

Emergency dialing

Dial 993/995/991 from your phone at any time — emergency calls bypass SIM restrictions and connect through any available network in Brunei. Having the eSIM active adds the ability to share live location, look up hospital addresses, and contact your embassy through data-based channels.

Battery impact

Expect 10-15% faster battery drain with two active SIM lines. Your phone maintains two radio connections simultaneously. If battery life matters during a long day, disable the home SIM and rely on the Brunei eSIM for everything including WhatsApp and iMessage. Re-enable the home SIM at night for any pending SMS codes. Carry a Type G adapter for charging in Brunei.

Hotspot

Using personal hotspot in Brunei on eSIM data

Sharing data via hotspot is straightforward on most Brunei eSIM plans. Enable Personal Hotspot in Settings and connect your laptop or tablet. DST's 4G network provides 4G speeds through hotspot, slightly below direct device connection to tethered devices. USB tethering offers the most stable connection and charges your phone simultaneously — a practical choice for hotel work sessions. WiFi tethering suits quick connections at cafes or airports.

Provider restrictions

Some budget eSIM plans block hotspot at the carrier level. If personal hotspot is grayed out in Settings, your plan does not include it. Contact your provider before departure to confirm tethering is supported. Airalo and Saily include hotspot on most plans. Holafly's unlimited plans restrict tethering on some Brunei data packages — check the plan details page before purchase.

Data impact

Data drains faster through hotspot. Desktop browsers load full-resolution images and scripts that mobile browsers skip. Expect 150-200 MB per hour for browsing, 1.5-3 GB per hour for video, and 300-500 MB per hour for video calls. Disable auto-play videos and pause cloud backups on any device connected to your Brunei eSIM hotspot.

VPN

Brunei VoIP restrictions: VPN required before departure

VoIP services do not work on DST's network in Brunei without a VPN. WhatsApp calls, FaceTime, Telegram voice, and Skype are all affected. Text chat and media sharing in these apps function normally — the block targets real-time audio and video streams only. Install a VPN before you board: NordVPN or ExpressVPN are reliable in Brunei. Surfshark offers a budget option. Test the connection at home to confirm your subscription is active. Do not wait until arrival — VPN app downloads may be blocked on Brunei's network.

VPN use for personal privacy is generally legal

Affected apps: Blocked: WhatsApp calling, FaceTime, Skype, Zoom (audio), Google Duo/Meet, Viber, Telegram calls, Discord voice. Working without VPN: text chat, photo/video sharing, voice messages (pre-recorded), document transfer in WhatsApp/Telegram/iMessage.

WiFi Backup

Setting up eSIM in Brunei: WiFi backup plan

WiFi in Brunei: moderate WiFi in urban areas; spotty in rural regions. eSIM installation requires a brief WiFi connection for the QR code scan (under 1 MB of data). Hotel WiFi works, but home WiFi before departure is the safest option. Captive portals at Brunei's main airport and public hotspots sometimes block the carrier server the eSIM download needs.

Activating without WiFi

Manual activation fallback: every eSIM order includes an SM-DP+ server address and an activation code in the confirmation email. Instead of scanning the QR code, enter these values manually. iPhone: Settings > Cellular > Add eSIM > Enter Details Manually. Samsung: Settings > Connections > SIM Manager > Add eSIM > Enter Code. This works over any data connection, including your home carrier's mobile data. The transfer is under 1 MB.

Multi-Country

Managing eSIM profiles: Brunei + other destinations

Planning a multi-stop Asian itinerary that includes Brunei? Install a dedicated eSIM for each country before you leave. Single-country plans connect to the primary local carrier (DST in Brunei) and deliver better speeds than regional eSIMs that route through roaming agreements. Your phone holds up to 8 eSIM profiles — switching between them at each border takes 30 seconds. Label each profile with the country name for quick identification.

Switching eSIM profiles between countries

Switching eSIMs at the border: go to Settings, find your SIM/eSIM list, turn off the previous country's profile, and enable Brunei. Set the Brunei eSIM as your data line and enable data roaming for that line specifically. DST picks up within 60-90 seconds. Keep all other profiles saved — they occupy no data until re-enabled.

Fixes

Common problems and fixes

"eSIM Not Supported" error

Cause: Your phone is carrier-locked or the model does not support eSIM.

Fix: Contact your home carrier to unlock (24-72 hours). Verify your model supports eSIM at our compatibility list.

"Unable to Activate eSIM" error

Cause: eSIM profile slot is full, or the QR code was already redeemed.

Fix:Delete unused eSIM profiles in Settings > Cellular. iPhones hold 8 profiles (2 active). If the QR shows as used, contact your provider for a replacement code.

Connected but no data

Cause: Data roaming is off on the travel eSIM, or data is routing through the home SIM.

Fix:Settings > Cellular > select travel eSIM > Data Roaming ON. Also verify: Settings > Cellular > Cellular Data > select the travel eSIM as your data line. Restart your phone after making changes.

VPN configuration after setup

VPN services in Brunei face restrictions. Some commercial VPNs connect intermittently; government-approved VPNs may log traffic. The practical advice: install and configure your VPN before departure. Saily includes VPN protection from NordVPN alongside its eSIM data plan. For travelers who need encrypted connections for banking, email, or corporate access, having VPN pre-configured before landing saves troubleshooting time. Cellular data through your eSIM provides a more stable VPN tunnel than public WiFi networks.
