900 of these 1575 plans were checked against the seller's own shop on 17 October 2026. The rest come from the seller's own feed or plan pages and are not yet independently checked.
The Watchdog Pick is chosen automatically: the lowest real price per GB of the 1575 plans in this view. Bulk data pools above 50 GB cannot win it, because their per GB rate only exists if you use data no traveller uses. Providers cannot pay for it, and a commission never changes the ranking. Prices are shown in USD and can change at checkout.
Price per GB counts only data you can use inside the validity, at most 3 GB a day, so a big pool on a short validity cannot buy the top spot. Every provider's best two plans come first, then the rest. A plan marked Unverified price undercuts every other provider here by more than half and waits at the end until we have checked it on the seller's site. How we rank
Unlimited rows show the daily amount at full speed. Some rows also show the speed after that amount. A row with no speed does not mean the plan stays fast, so check the plan on the seller's site.
Some links here earn us a commission. It never changes the order. How we make money The row marked Sponsored is a paid placement shown above the ranking, not part of it. Advertise here.

Cheapest eSIM for Vietnam: the numbers
As of 17 October 2026, 06:01 GMT, the cheapest eSIM for Vietnam is SogdiaRoam with 38 GB for 11 Days at $9.90. That is $0.30 per GB, the best rate of the 1575 plans we compare from 58 providers. 964 plans include 5G. 613 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which is the best eSIM for Vietnam?
There is no single best eSIM for Vietnam, because the right plan depends on how long you stay and how much data you use. What we can do is rank the 1575 plans on the numbers, as they stand on 17 October 2026:
- Best value overall SogdiaRoam, 38 GB for 11 Days at $9.90. That is $0.30 per GB, the lowest real rate of every Vietnam plan we track.
- Best for a short trip Superalink, 1 GB for 1 Day at $0.75. The cheapest ticket that still gives you at least 1 GB for a week or less.
- Best for a long stay ASIMGO, 50 GB for 30 Days at $23.97, $0.48 per GB. The best rate among plans that last 30 days or more.
- Highest daily cap on an unlimited plan SimSmash, 1 Day at $7.99, full speed up to 10 GB a day. Set that daily cap against the fixed plan above before you pay for the word unlimited.
None of these picks is chosen by a person. Each one is the first row of a sort on live prices, so it changes whenever a provider moves a price, and SogdiaRoam did not pay to be named here.
Which mobile networks does Vietnam have?
Vietnam's 5G reached 90% of the population by February 2026, with close to 40,000 base stations installed and about 23 million 5G subscribers.
- Viettel: Viettel, run by the military, is the largest operator with the widest rural and mountain coverage, over 30,000 5G stations, and Vietnam's only fully standalone 5G network.
- Vinaphone: Vinaphone, the VNPT brand, has posted the fastest average download speeds at around 31.8 Mbps and performs strongly in Hanoi, Da Nang and Ho Chi Minh City.
- MobiFone: MobiFone is the third national network with solid city coverage but a thinner footprint than Viettel once you leave urban areas.
A handful of MVNOs resell the main networks, but tourist SIMs and travel eSIMs almost always run on Viettel, Vinaphone or MobiFone.
The eSIM plans we compare on this page connect to:
The list above is Vietnam's operator market. The badges are the networks our tracked plans actually roam onto, which can be a subset of it, and the same network is sometimes sold to roaming partners under a different brand name. So a guide praising an operator you do not see badged here is describing a local SIM, not the travel eSIMs compared above.
Is 5G available in Vietnam?
Viettel has the widest 5G, with 90% outdoor coverage and a target of 98% of the population during 2026, while VNPT is expanding on newly licensed 700 MHz spectrum from mid 2026.
How much data do you need in Vietnam?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Vietnam right now:
Are unlimited eSIMs for Vietnam really unlimited?
Not always. 614 of the 1575 plans above are sold as unlimited, and most of them carry a daily fair use cap. A further 16 plans are unlimited in a different way: one capped speed for the whole plan, shown next to the word Unlimited in the table. For Vietnam the caps we can see published are 0.5 to 10 GB a day: past that the speed drops, often to 1 Mbps or less, until the clock resets. That is fine for messages and maps, slow for video. At $0.30 per GB from SogdiaRoam, a fixed plan often works out cheaper than unlimited unless you genuinely burn several GB a day. That is why we rank by price per GB and not by the word on the label.
Here is what each seller on this page actually allows per day before it slows you down. No seller publishes this next to its rivals, which is exactly why it is worth showing.
Every seller that publishes a daily allowance is listed on our daily data caps page, with the cheapest plan at each one. The gap between the top and bottom of that table is the whole point. Two plans both sold as unlimited can differ several times over in what you actually get at full speed, and the cheaper one is not always the smaller allowance.
eSIM or a local SIM card at the airport in Vietnam?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter for a tourist SIM card. Data for Vietnam starts at $0.25 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Vietnam eSIM
Pick the plan, not the brandThe cheapest rate in Vietnam today is $0.30 per GB from SogdiaRoam, against a median of $1.68. The QR code arrives by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Installation needs a connection, and the one thing you will not have when you land in Vietnam is a working connection.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to attach to MobiFone, VINAPHONE, VNPT, VNPT International, Vietnamobile, Viettel, Viettel Mobile, Vinaphone, Vms Mobifon. Expect 5G where the network reaches, 4G everywhere else.
Know what happens when it runs out613 of the 1575 plans here can be topped up, so running out is not the end of the trip. If you would rather over buy than top up, the cheapest plan with at least 5 GB is ASIMGO at $2.54.
Good to know before you land in Vietnam
Physical SIMs must be registered in person with your passport at official carrier stores, which takes 10 to 20 minutes. eSIMs bought before arrival skip the paperwork.
Viettel, Vinaphone and MobiFone counters at Tan Son Nhat sell tourist SIMs for roughly 200,000 to 400,000 VND, about 8 to 16 dollars. Viettel's TOUR200 package at 200,000 VND gives 5 GB per day for 7 days plus calls.
For Ha Giang, Sapa, Cao Bang or anywhere in the northwest mountains, Viettel is the safe choice. Its 4G reaches valleys where the other networks drop to 3G or nothing.
Vietnam Travel eSIM FAQ
Everything you need to know about using an eSIM in Vietnam
What is the cheapest eSIM for Vietnam?
Right now the cheapest option ranked by price per GB is SogdiaRoam with 38 GB for 11 Days at $9.90. That works out to $0.30 per GB. Prices change often, so the table above is re-sorted at every price check.
Which is the best eSIM for Vietnam?
It depends on the trip, so we rank rather than pick a favourite. On today's prices the best value for Vietnam is SogdiaRoam at $0.30 per GB, the lowest real rate of the 1575 plans we compare. For heavy daily use there are 614 unlimited plans, most with a daily fair use cap, and they only win if you genuinely burn several GB a day. Every pick on this page is the first row of a sort on live prices. No provider can pay to be named best.
Is eSIM available in Vietnam?
Yes. We track 1575 prepaid travel eSIM plans from 58 providers that work in Vietnam, roaming onto MobiFone, VINAPHONE, VNPT, VNPT International, Vietnamobile, Viettel, Viettel Mobile, Vinaphone, Vms Mobifon. You need a phone that supports eSIM and is not locked to a carrier; most iPhones from the XS onward and most flagship Android phones from 2019 on qualify.
Which networks will my eSIM connect to in Vietnam?
The plans we compare connect to MobiFone, VINAPHONE, VNPT, VNPT International, Vietnamobile, Viettel, Viettel Mobile, Vinaphone, Vms Mobifon. The exact network depends on the plan you pick. Check the plan details before you buy if one network matters to you.
Do Vietnam eSIMs support 5G?
964 of the 1575 plans we track for Vietnam include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I buy a Vietnam eSIM online before I travel?
Yes, and you should. Every plan on this page is sold online and delivered by email as a QR code within minutes. Install it on wifi at home, leave the line switched off, and turn on data roaming for it when you land in Vietnam. The validity clock on most plans only starts when the eSIM first connects.
Can I top up my Vietnam eSIM if I run out?
Yes. 613 of the 1575 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Is an eSIM cheaper than a local SIM card in Vietnam?
For a trip of days or weeks, usually yes. Data for Vietnam starts at $0.25 for 100 MB on this page, with no queue, no shop and no passport handed over at a counter. A local SIM card can still win if you stay for months or need a local phone number.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
Does a Vietnam eSIM work on iPhone and Android?
Yes, on any carrier unlocked phone with eSIM support: iPhone XS or newer, Google Pixel 3 or newer, Samsung Galaxy S20 or newer and most recent flagships. The plans are identical on both; only the install steps differ, and both take about a minute on wifi.
How many GB do I need for a week in Vietnam?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is ASIMGO at $2.54.
Which Vietnam eSIM gives the most data per day?
Of the plans sold as unlimited here, SimSmash allows the most at full speed, 10 GB a day from $7.99. The smallest allowance on this page is 500 MB a day, from 8 sellers. Every one of them is advertised as unlimited, and past the daily allowance the speed drops, often to 1 Mbps or less, until the next day. Check the allowance, not the word.
