Stay connected in Vietnam with instant mobile data — no roaming fees, no physical SIM.
Most phones released since 2018 support eSIM, including recent iPhone, Samsung Galaxy, and Google Pixel models.
Check device compatibilityA Vietnam eSIM gives international visitors mobile data without having to find a physical SIM card after landing. Purchase online, install the eSIM digitally and use it for Google Maps, Grab, translation, messaging, hotel bookings and other travel services.
BDAtrip lists prepaid Vietnam travel eSIM plans for short holidays, business trips and longer stays. You can compare data allowance, validity, network and price before choosing a package. Plans range from light-use options to larger daily-data and unlimited packages.
The same travel eSIM can be used in Hanoi, Ho Chi Minh City, Da Nang, Hoi An, Nha Trang, Hue, Ha Long, Phu Quoc and other covered destinations while the plan remains valid. Coverage and speed vary by location, network conditions, device and the specific package selected.
Depending on the selected package, a Vietnam eSIM may connect to Viettel, VinaPhone, MobiFone or another supported network. Many plans shown on BDAtrip include access to one or more of Vietnam’s major mobile networks, and both 4G/LTE and 5G options are available.
If you specifically want a Viettel eSIM for Vietnam, open the details of the plan before purchase and confirm that Viettel Mobile appears in its supported-network list. Do the same when choosing VinaPhone or MobiFone. Network availability is plan-specific and may change automatically as you travel.
Mobile data is widely available in Hanoi and other major cities and tourist areas, but service can be less consistent in remote mountains, islands and rural locations. Actual speed depends on local coverage, congestion, the selected network and your phone’s capabilities.
The best Vietnam eSIM is the plan that matches the length of your trip, expected usage and required features. Compare these details before buying:
Data allowance: Small fixed-data plans suit maps, messaging and occasional browsing. Larger or daily-data plans are better for social media, video calls and frequent uploads.
Validity: Select a plan that covers the full trip. Available options include short-term packages, 8–15 day plans, 16–30 day plans and longer validity periods.
Network: Check whether the plan uses Viettel, VinaPhone, MobiFone or another listed operator.
4G or 5G: A 5G plan also requires compatible hardware and local 5G coverage.
Hotspot support: Confirm tethering in the package details if you need to share data with a laptop or another traveler.
Calls, SMS and phone number: Many travel eSIMs are designed primarily for mobile data. Never assume a plan includes a Vietnamese phone number, calls or SMS unless these features are explicitly listed.
Fair-use policy: An unlimited Vietnam eSIM may include a daily high-speed allowance or a reduced speed after a threshold. Read the plan’s fair-use terms before purchase.
A cheaper package is not always the best value if it expires before the end of the trip or does not include enough high-speed data. Compare the complete plan details, not price alone.
A prepaid Vietnam eSIM lets you purchase travel data in advance without signing a long-term mobile contract. Unlike a physical SIM card, an eSIM is a digital profile installed on a compatible phone using the supplied activation details.
Choose a fixed-data package when you want a defined allowance for the full validity period. Choose a daily-data plan when you prefer a fresh allowance each day. For heavier use, compare the available unlimited Vietnam eSIM options and review any high-speed limit, fair-use policy and hotspot restriction shown in the individual plan.
If you need a Vietnam eSIM with a phone number, voice calls or SMS, verify those features before checkout. A data-only eSIM can still support internet-based calls and messages through apps such as WhatsApp, Messenger and FaceTime, but it does not automatically provide a local mobile number.
Recent iPhone, Samsung Galaxy, Google Pixel and other devices may support eSIM, but compatibility depends on the exact model, country of purchase and carrier restrictions. Your phone must be both eSIM-compatible and network-unlocked.
For an iPhone—including an iPhone 14—open Settings > Cellular/Mobile Data and look for Add eSIM. If that option is unavailable, confirm the model’s specifications and lock status before buying. Some models sold in particular markets may have different SIM capabilities.
You can usually keep your physical SIM active while using the Vietnam eSIM for mobile data on a dual-SIM device. To avoid unexpected roaming charges, select the eSIM as the mobile-data line and review the data-switching settings on your phone.
Choose a plan: Compare data, validity, supported networks and package conditions.
Buy the Vietnam eSIM online: Complete checkout and receive the QR code or activation information digitally.
Install before departure: Add the eSIM while connected to reliable Wi-Fi, but first check when the selected package’s validity begins.
Connect after arrival: Select the eSIM for mobile data and enable data roaming if required by the plan instructions.
Keep the activation details: Do not delete the eSIM until the trip and validity period have ended; some profiles cannot be installed again after removal.
Installation and activation rules can differ between packages. Always follow the instructions supplied with your selected eSIM.
Travelers researching Airalo Vietnam, Holafly Vietnam, Gigago Vietnam or a Vietnam Discovery eSIM should compare plan-level features rather than relying on a provider name alone. Check the amount of high-speed data, validity, supported Vietnamese networks, 4G/5G availability, hotspot rules, activation policy and final price.
BDATrip lets you compare multiple Vietnam eSIM packages in one place. Use the filters above to narrow the results by data allowance, validity and network generation, then open the plan details before purchase. Availability and package conditions can change, so the individual product listing is the source of truth.
