Best eSIM for Vietnam (2026): Reliable Data for a Full North–South Trip
I have traveled all over Vietnam, from Hanoi and the northern mountains through central Vietnam and down into the south. On those trips I used mobile data constantly: for Grab, maps, train and bus times, hotel messages, weather checks and the usual last-minute changes that happen when you are moving around the country. That is why I would not pick a Vietnam eSIM just because it is cheap. In the big cities, most decent plans work. The differences become much more noticeable once you start covering real distance.

The Vietnam eSIM I would check first
For a full Vietnam trip, I would start with Orange Travel. Its current Vietnam plans list Viettel as well as several other local networks, which is useful once your route goes beyond Hanoi, Da Nang and Ho Chi Minh City. If your trip is mostly cities, or you mainly care about lots of data, Nomad, Yesim and Maya can also make sense.
Check Orange Travel Vietnam plansI checked the plan details and listed network partners again in September 2026. These can change, so always have one last look before buying.
| eSIM | Best for | Networks currently listed | My take |
|---|---|---|---|
| Orange Travel | Long, varied Vietnam trips | Viettel, VNPT, MobiFone, GTEL and Vietnamobile | The first one I would check for a north–south itinerary. |
| Nomad | Cities, coast and easy setup | Vietnamobile, MobiFone and VinaPhone | A good alternative when your trip is not heavily mountain-focused. |
| Yesim | Flexible data and heavier use | Automatic network switching; operators are not clearly named on the current product page | Interesting for bigger data needs, but I would like clearer network information. |
| Maya Mobile | Simple unlimited-style plans | MobiFone in Maya’s current network directory | Easy to understand, but check the daily high-speed allowance. |
Orange Travel
My first choice for a varied route because the current Vietnam plan openly lists Viettel plus several backup networks.
Nomad
A simple, familiar option for city and coastal travel, with clear fixed-data plans and an easy app.
Yesim
Worth comparing if you want bigger data packages, pay-as-you-go or unlimited-style options.
Maya Mobile
A straightforward choice if you would rather buy by number of days than keep watching a fixed GB allowance.
If you want to understand the difference between Viettel, MobiFone and VinaPhone themselves, I cover that separately in my Vietnam mobile network comparison. Here I am keeping the focus on which travel eSIM makes sense for which kind of trip.
What matters on a long trip through Vietnam
Vietnam is one of those countries where a plan can feel perfect for several days and then suddenly become less convincing once you leave the easy part of the route. Hanoi, Da Nang and Ho Chi Minh City have plenty of coverage. The real test is the time in between: mountain roads, smaller towns, long bus journeys, rural stretches, caves, islands and the Mekong Delta.
That is where I care less about whether one provider is a few dollars cheaper and more about whether I can still open a map, message my accommodation or find a Grab when I need one. I have had plenty of travel days in Vietnam where the phone was not entertainment; it was part of getting from A to B.
I also check the network behind the eSIM before buying. Some providers tell you exactly which Vietnamese networks are included. Others do not. That matters more to me in Vietnam than it does in a compact city-break destination.
Hanoi is the easy part. The more useful test comes once you start moving between very different parts of Vietnam.
How I compare Vietnam eSIMs
I keep the comparison fairly simple. I want to know which local network the plan uses, whether the data allowance matches the length of my trip, whether hotspotting is allowed when I need it, and whether I can install and top up the eSIM without wasting time.
Which local network does it use?
This matters much more once the trip includes mountains, rural areas or long overland journeys.
Does the plan fit the trip?
A cheap 5 GB plan is great if you barely use data. It is annoying if you need to top it up every few days.
Can I hotspot?
I sometimes work while traveling, so tethering matters to me. If you only use your phone, it may not matter at all.
Can I sort everything out before arrival?
I prefer installing the eSIM before flying and landing with data ready to go.
Which eSIM fits your Vietnam itinerary?
Orange Travel
This is where I value the current access to Viettel plus several other local networks most.
Orange or Nomad
Once the mountains and remote areas disappear from the itinerary, the choice becomes much more about price, data and app preference.
Yesim or Maya
Both are worth checking if you use a lot of data, but read the hotspot and fair-use details before buying.
Consider a regional plan
If convenience matters more than having the strongest Vietnam-specific setup, see my Nomad APAC eSIM review.
Northern Vietnam is where I become pickier
Hanoi itself is easy. Sapa, Lao Cai and the mountain roads are not. Terrain makes a real difference, and this is the part of Vietnam where I would pay closest attention to the local network included with the eSIM.
If the far north is a major part of your trip, use my best eSIM for Sapa and northern Vietnam guide. I go into much more detail there without turning this main Vietnam guide into a second network article.
Around Sapa and the northern mountains, I care far more about the network behind the eSIM than I do in central Hanoi.
Central Vietnam: the cities are easy, the journeys between them matter more
Da Nang and Hoi An are straightforward. What matters more to me is the rest of central Vietnam: Phong Nha, longer road or rail journeys, rural areas and days when I am constantly checking where I am going next.
For that kind of trip, I like having one eSIM installed for the whole country rather than thinking about connectivity again every time I move to another province.
Phong Nha is a good example of why I judge a Vietnam eSIM by more than how it performs in the big cities.
Along the coast: Nha Trang and long travel days
Vietnam’s coastal route is much easier for mobile data than the mountains. If your trip sticks mainly to Hanoi, Da Nang, Hoi An, Nha Trang and Ho Chi Minh City, I would worry less about having Viettel specifically and pay more attention to price, plan size and ease of use.
That is where Nomad becomes more attractive to me. Its current Vietnam plan does not list Viettel, but it does list VinaPhone, MobiFone and Vietnamobile, which can be perfectly reasonable for a city-and-coast itinerary.
On a coastal itinerary, plan size and ease of top-up start to matter almost as much as the underlying network.
Southern Vietnam and the Mekong Delta
Ho Chi Minh City is another easy place for mobile data. The Mekong Delta is more mixed: you spend more time on smaller roads, around rivers and in rural areas, and that is where I again prefer knowing exactly which networks my eSIM can use.
For the detailed Viettel, MobiFone and VinaPhone comparison, see my Vietnam mobile network guide. For choosing the eSIM itself, my rule is simpler: the more varied the route, the more I value a plan with clear network information.
The Mekong Delta is one of the places where I would rather know what network I am getting than save a tiny amount on the eSIM.
What about Phu Quoc?
If Phu Quoc is just a few days at the end of a longer Vietnam trip, I would normally keep the same eSIM and avoid making things more complicated. If the island is the main part of your trip, see my best eSIM for Phu Quoc guide for island-specific advice.
How much data do you need in Vietnam?
For normal travel use—Google Maps, Grab, messaging, email, restaurant searches and checking transport—5 to 10 GB per week is a comfortable starting point. You can use less if you rely heavily on hotel Wi-Fi. You can use far more if you upload video, stream or tether a laptop.
I would not automatically buy an unlimited plan. Some “unlimited” eSIMs slow down after a daily high-speed allowance, so the wording matters. If you work remotely or use a lot of data, compare my best unlimited data eSIM for Vietnam guide before deciding.
A simple rule of thumb
Light use: around 5–10 GB per week.
Longer trip with lots of maps and uploads: I would rather have 10–20 GB and not think about it.
Remote work or tethering: compare unlimited-style plans and check the fair-use rules.
eSIM before arrival or a local SIM at the airport?
I like travel eSIMs because I can install one before leaving home and have data as soon as I land. After a long flight, opening Grab immediately is worth something to me.
A local SIM can still be cheaper, and it may be the better choice if you specifically want a Vietnamese phone number. I compare both options in my Vietnam eSIM vs local airport SIM guide.
If you actually need a Vietnamese number for normal calls or SMS, most international travel eSIMs are the wrong product. See my Vietnam eSIM with a local phone number guide instead.
How I set up an eSIM before flying to Vietnam
Check that your phone supports eSIM and is unlocked
Do this before paying. An eSIM-compatible phone can still be locked to a carrier.
Install it on reliable Wi-Fi before the trip
I would rather deal with the QR code or app at home than in an airport arrivals hall.
Keep your normal SIM active if you still need your number
On a dual-SIM phone, I keep my usual line for incoming SMS and use the Vietnam eSIM for data.
Set the Vietnam eSIM as the data line
Enable data roaming on the travel eSIM if the provider tells you to; that is normal for many travel eSIMs.
Turn off mobile-data switching
This helps stop the phone from falling back to your home SIM and creating expensive roaming charges.
What I would choose for different Vietnam trips
| Your trip | I would check first | Why |
|---|---|---|
| Three to four weeks north to south | Orange Travel | Its current plan lists Viettel plus several other Vietnamese networks. |
| Hanoi + Da Nang/Hoi An + Ho Chi Minh City | Orange or Nomad | The route is less demanding, so price, data size and app preference matter more. |
| Sapa and the far north | Read the northern Vietnam guide first | Mountain travel deserves a more specific network check. |
| Remote work or lots of tethering | Yesim or Maya | Both are worth comparing for higher data use, but check the limits carefully. |
| Vietnam plus several Asian countries | Regional eSIM | One plan is convenient, but you may give up the best Vietnam-specific network setup. |
| Need a Vietnamese phone number | Local-number option | Most travel eSIMs are data-only. |
After traveling through very different parts of Vietnam, I would choose an eSIM for the route I am actually taking, not just the cheapest price on the screen.
Vietnam eSIM FAQs
What is the best eSIM for Vietnam in 2026?
For a full north–south trip, I would check Orange Travel first because its current Vietnam plans list Viettel along with several other local networks. For a mainly city-and-coast trip, Nomad is also easy to consider. Yesim and Maya are more interesting if you expect to use a lot of data.
Which Vietnam eSIM uses Viettel?
Orange Travel currently lists Viettel among its Vietnamese partner networks. These agreements can change, so check the plan page again before buying. For the carrier comparison itself, see my Vietnam mobile network guide.
Is Nomad good for Vietnam?
Yes, especially for cities and the coastal route. Nomad currently lists Vietnamobile, MobiFone and VinaPhone in Vietnam. I would compare it more carefully with other options if the northern mountains or remote rural areas are a big part of the trip.
Is an unlimited Vietnam eSIM worth it?
Only if you actually use a lot of data. For normal travel, a fixed-data plan is often cheaper. If you tether, work remotely or upload a lot of video, an unlimited-style plan can be useful, but read the high-speed and fair-use limits first.
How much data do I need for two weeks in Vietnam?
For maps, Grab, messaging, email and normal browsing, around 10–20 GB gives most travelers a comfortable buffer. Heavy video, remote work and hotspot use can push that much higher.
Can one eSIM cover a full Vietnam trip?
Yes. One national Vietnam eSIM can work from Hanoi to the south as long as the plan remains valid and has data left. What changes from place to place is the strength of the local network behind it.
Do I need a Vietnamese phone number?
Most tourists do not. Grab, maps, WhatsApp, Messenger and most travel tasks work with data. If you do need normal local calls or SMS, see my Vietnam eSIM with local number guide.
Should I buy a Vietnam eSIM or a Southeast Asia eSIM?
If Vietnam is the main trip, I prefer a dedicated Vietnam plan. If you are crossing several countries, a regional plan can be easier. See my best eSIMs for Southeast Asia for that comparison.
What I would buy again
If I were setting up data for another full trip through Vietnam now, I would start with Orange Travel Vietnam. I like that I can see Viettel and several other Vietnamese networks listed before buying, and that suits the way I travel around the country.
If my trip were mainly Hanoi, the central coast and Ho Chi Minh City, I would also compare Nomad Vietnam. For heavy data use, I would look at Yesim Vietnam and Maya Mobile, then choose based on the current high-speed and hotspot rules.
That is really the whole point: Vietnam is too varied for me to choose an eSIM from price alone. I want a plan that fits the trip I am actually taking.

I’ve just bought an Airalo eSIM on your recommendation as we are heading to the north of Vietnam. After purchase the app reports that it uses Vinaphone only. I’ve had confirmation from one of their agents too. You may wish to update your advice.
Saul, thank you for mentioning it. This has been a very recent change and I will update the guides immediately.
