You can install the eSIM before arriving at your destination, activate the package after arriving at your destination, and the usage date will start counting.
An internet connection is required to install the eSIM. We recommend installing it before departure or using the free airport Wi-Fi at your destination.
A QR code can only be scanned once with one mobile phone, and the device cannot be changed after binding.
Days are calculated based on the number of hours after the eSIM is activated. (If a user purchases a 3-day data plan and activates it at 10:00 AM on September 1st, this plan will expire at 9:59 AM on September 4th.)
The eSIM is valid for 90 days, starting from the order date. Please activate it within the validity period.
Please turn off the data roaming function of the original SIM Card to avoid high roaming fees
Once installed, an eSIM can be deleted and reinstalled on the same device up to 10 times. An eSIM can be reinstalled within the validity period of the QR code (for an inactive eSIM) or the plan (for an activated eSIM). Once the validity period has expired, it cannot be reinstalled.
If an error message appears after scanning, it doesn't mean the eSIM is invalid. Restart your phone and go to Settings > Mobile Services to check if the eSIM has been added. Alternatively, contact customer service for assistance. Do not scan additional QR codes, as this will cause multiple eSIMs to be installed on one phone.
For iPhones, please delete the description file (check steps: Settings -> General -> Device Management, scroll to the bottom, if there is no description file, it means it is normal) to avoid problems with smooth use.
Telecom network quality varies from country to country. Each country's geography and telecommunications infrastructure vary. Refunds cannot be requested due to signal issues in certain areas. If you experience poor signal quality, you can manually switch carriers. To switch carriers: Select Network/Carrier > Auto Disable > Search to select a carrier.
To maintain network quality and adhere to the Fair Usage Policy (FUP), telecommunications companies around the world sometimes impose data limits on customers who use a significant amount of data in a short period of time. This may result in internet access interruptions or slower speeds. To ensure a stable internet connection, please avoid prolonged viewing or downloading of videos, software updates, sharing your internet connection (hotspot) with others, or other activities that consume a large amount of data.
If the eSIM plan is not fully used or is deleted without the approval of customer service, no reissue or refund will be made.

APN: smartone
Valid within 90 days from the order date, invalid after the expiration date
In Brunei, you can generally expect a stable 4G network experience when using an eSIM. Services like the Brunei eSIM provide high-speed 4G data daily, which is sufficient for typical online activities such as browsing, navigation, and social media. While 5G networks are being developed, 4G remains the predominant high-speed mobile standard for most travelers. The actual speed may vary depending on your specific location and network congestion.
Yes, reliable internet connectivity is generally available for travelers in Brunei, especially within urban areas like Bandar Seri Begawan. Utilizing an eSIM service designed for Brunei helps ensure you can stay connected. These services leverage established local mobile networks to provide access for navigation, communication, and searching for local information, making it easier to manage your trip and access essential travel tools.
While there are no specific laws strictly prohibiting the use of VPNs in Brunei for personal use, the government does regulate internet content. It is generally advisable for visitors to use VPN services responsibly and remain aware of local laws and cultural norms regarding online behavior. Using a VPN for legitimate purposes such as securing your data on public Wi-Fi is common, but be mindful of content access restrictions.
eSIM service for Brunei is increasingly available and is compatible with most modern smartphones and devices that support eSIM technology. Travelers can easily activate an eSIM by scanning a QR code, which eliminates the need for a physical SIM card. This makes it a convenient option for ensuring connectivity without device trivialities, providing immediate access to mobile data upon your arrival.
Free Wi-Fi is available in many hotels, cafes, restaurants, and at Brunei International Airport. While these public Wi-Fi networks can be convenient for occasional use, they may sometimes offer slower speeds or less security. For consistent and secure internet access throughout your trip, especially when navigating or using apps on the go, an eSIM offers a more reliable and private connection than solely depending on public Wi-Fi.
With a Brunei eSIM, once you exceed your daily allocated high-speed data (e.g., 500MB or 1GB, depending on your purchased plan), the internet speed will typically be reduced to a slower rate, such as 128kbps. While this reduced speed is usually sufficient for basic messaging and light browsing, it may not be ideal for activities requiring significant bandwidth like video streaming or heavy data downloads until the next day's high-speed allowance resets.
The installation process for a Brunei eSIM is remarkably simpler than with a physical SIM card. You typically receive a QR code via email after your purchase. To activate, you simply scan this QR code using your device's settings and follow a few on-screen prompts. This process eliminates the need for a SIM tray tool, swapping physical cards, or worrying about losing your home SIM, offering a completely hassle-free setup.
Generally, you can expect consistent internet connectivity in Brunei's major urban areas and popular tourist destinations when utilizing an eSIM. Network coverage is strongest in areas like Bandar Seri Begawan and along main transportation routes. While connectivity in more remote or rural regions might be less consistent, eSIMs utilize established local networks to provide the best possible coverage, helping you stay connected throughout your travels.
