Confirm that your phone is unlocked and eSIM-compatible. Install before your flight, but follow the plan's activation instructions. Coverage and speed depend on the local partner network, terrain, congestion, and your device.

Vietnam eSIM prices at a glance
Choose a 15- or 30-day trip and compare the same data allowance in USD. A dash means we could not verify an exact matching plan—not that the provider has no Vietnam products.
Trip length
For fixed data, the table shows the shortest verified validity that covers your trip. Unlimited appears only when the exact 15- or 30-day duration is publicly verifiable.

Independent buying guide
How to choose a Vietnam eSIM for a real itinerary
Vietnam is a long country, so a plan that works well in central Hanoi can still slow down on a mountain road, island or boat route. Compare local network information, activation and fair-use rules first; use the price table only after the product fits your route.
Research reviewed Aug 12, 2026Fixed data is usually enough
For a city-focused 7–10 day trip, 5–10 GB normally covers navigation, translation, messaging and bookings. It is easier to control than an unlimited plan with an unclear daily speed threshold.
Check network disclosure
For trains, buses and multiple regions, prefer a product that names its Vietnamese partner or explains network selection. Coverage quality changes with terrain and congestion.
Compare MobiFone Vin Travel
The official tourist eSIM includes Vietnamese data and voice bundles. It is not directly equivalent to the data-only travel eSIMs in our price table, but it can be better for travellers who need local calling.
The practical differences between the three travel eSIMs
Product names, partner networks and fair-use limits can change. Check the package card again immediately before purchase.
| Provider | Local network | When it starts | Hotspot | Top-up & refunds |
|---|---|---|---|---|
| AAiralo | Current Vietnam fixed-data listings identify VinaPhone/VNPT as the primary local partner; the exact network still depends on the selected product. | Validity generally begins when the eSIM first connects to a supported Vietnamese network, unless the package activation policy says otherwise. | Supported when the device and local network allow it; manual APN setup can sometimes be needed. | Selected packages support top-up. Refund and replacement options narrow after installation, activation or use. |
| SSaily | A partner is selected automatically. The public Vietnam page does not promise one named network across every plan. | Install before departure; the plan is designed to activate automatically after the first connection in Vietnam. | Saily says hotspot use is allowed on its Vietnam eSIM, with normal phone and network limitations. | Support and plan management are app-based. Refund eligibility is strongest before the eSIM is installed or activated. |
| YYesim | The plan connects to supported Vietnamese partner networks; availability can vary by package and place. | Validity starts on the first supported connection and unused plans have an activation deadline stated by Yesim. | Available on most plans, although Yesim cannot guarantee it for every operator and device combination. | Top-up is available. Unlimited packages can be slowed by partner fair-use rules after heavy consumption. |
Prepare for cities, trains and rural stretches
The same setup works nationwide, but offline preparation matters more when you leave major urban areas.
- 01
Check compatibility and install
Confirm eSIM support and carrier-unlocked status, then install on reliable Wi-Fi before leaving home.
- 02
Save route essentials
Download offline maps, accommodation addresses, train or bus tickets and translation packs for mountain, boat and island segments.
- 03
Keep the home line under control
Turn off data roaming on your home SIM and disable cellular data switching. Keep the line on only if you need incoming SMS.
- 04
Troubleshoot in the right order
Wait for network registration, toggle airplane mode, restart once, then check data roaming and APN. Do not delete the eSIM unless support tells you to.

Plan by destination
One Vietnam eSIM from Hanoi to Ho Chi Minh City
Country plans are intended for use across Vietnam, but city coverage is not a promise of signal on mountain roads, islands, boats, or remote coastal stretches.
eSIM for Hanoi & Ha Long Bay
Maps, ride-hailing, translation, and tickets make mobile data useful from the airport. Hanoi is a different coverage environment from highways, boats, and caves around Ha Long Bay.
Save your hotel address, cruise booking, and offline maps before leaving the city.eSIM for Da Nang & Hoi An
The same Vietnam plan can cover both cities. Expect performance to vary between urban Da Nang, historic Hoi An, beaches, the Hai Van Pass, and rural day trips.
Download transport details before crossing mountain or coastal sections.eSIM for Ho Chi Minh City
Navigation, messaging, food delivery, and ride-hailing can use data throughout the day. Trips into the Mekong Delta can have less consistent coverage than central districts.
Keep accommodation and transfer information available offline.How much data for 7, 10, or 15 days in Vietnam?
These are planning ranges, not guarantees. Video quality, cloud backup, and hotspot use often matter more than trip length.
7 days
Five GB is a reasonable starting point for maps, chat, tickets, and light browsing. Choose 10 GB for frequent social video or calls.
Disable mobile photo backup if you choose 5 GB.10 days
Ten GB suits most independent trips with daily navigation, translation, searches, and occasional streaming.
A 30-day package may still be the shortest fixed plan covering ten days.15 days
Ten GB suits regular use; 20 GB is safer for video or hotspot use. Unlimited prioritizes convenience, but fair-use speed limits still apply.

How this comparison stays current
Airalo prices come from its official product feed and Vietnam page. Saily and Yesim are checked on their official Vietnam pages. The table compares only plan matches present in the latest validated snapshot. A dash means that no exact comparable plan was verified in that snapshot, not that the provider offers no other Vietnam plans. A scheduled job refreshes the snapshot every three days; the last verified value remains visible if a source is temporarily unavailable.

Vietnam eSIM questions
Which Vietnam eSIM is cheapest?
It depends on the allowance and trip length. Use the current comparison table above: it identifies the lowest checked price for the selected duration and data amount from the latest successful snapshot. Confirm the final price at checkout.
Will one eSIM work in Hanoi, Da Nang, and Ho Chi Minh City?
A Vietnam country plan is intended to work across those destinations. Actual coverage and speed still depend on the local network, terrain, congestion, and your phone.
Does unlimited mean unlimited full-speed data?
Not necessarily. Unlimited travel eSIMs can reduce speed after a daily high-speed allowance or under fair-use rules. Check the exact package terms before paying.
