The Best eSIM For Vietnam: My top 3 eSIMs I’ve tried in 2026
Finding the best eSIM for Vietnam used to stress me out more than packing did. I travel through Vietnam a few times a year, so I have wasted money on the wrong plans, lost signal halfway up a mountain, and figured out the hard way which providers actually deliver. After testing a stack of options in 2026, I trimmed my list down to three Vietnam eSIMs I would happily hand to a friend.
Here is the short version. For most travelers, Saily is the best eSIM for Vietnam overall. If you only want cheap, reliable data, Airalo is my budget pick. And if you stream, work remotely, or simply hate watching a data counter, Holafly’s unlimited plan wins. Below, I break down exactly why, what each one costs, and where each one let me down.
Can you use an eSIM in Vietnam?
Yes, and honestly it is the easiest way to get online here. Vietnam’s three big networks, Viettel, Vinaphone, and Mobifone, all support eSIM, so any decent travel provider can ride on them. Because you install everything by scanning a QR code, you skip the airport SIM queue completely. You also keep your home number active for banking texts and two-factor codes, which matters more than people expect.
First, though, check that your phone is unlocked and eSIM compatible. If it is, you can set up your Vietnam eSIM before you even leave home and land in Hanoi already connected.
My quick verdict on the best eSIM for Vietnam in 2026
I judged each Vietnam eSIM on four things: real-world coverage, speed, price per GB, and how painful the setup was. So here is how my top three stack up at a glance.
| eSIM | Best for | Network | Example plan & price | Hotspot |
| Saily | Best overall pick | Multi-network | 10 GB / 30 days, ~$17.99 | Yes, all plans |
| Airalo | Cheap + rural coverage | Viettel (Xin Chao) | 10 GB / 30 days, ~$20 | Plan dependent |
| Holafly | Unlimited data | All 3 networks | 15 days unlimited, ~$50.90 | Limited / capped |
Prices are correct at the time of writing, but eSIM plans change often, so always double-check on the provider’s site. Now let me get into the detail, starting with my overall winner.
1. Saily: the best eSIM for Vietnam overall
Saily comes from the team behind NordVPN, and that security background shows. Every plan includes an ad blocker, web protection, and a virtual-location feature, which you rarely get with a travel eSIM. More importantly, it simply worked across Hanoi, Da Nang, and Ho Chi Minh City whenever I needed maps or a quick Grab.
The pricing is good, too. At the time of writing, it starts at $3.99 for 1 GB and runs to about $17.99 for 10 GB over 30 days, so it usually undercuts other providers at the same data tier. There is also a 30-day unlimited plan around $71.99 if you want it.
Setup took me under two minutes in the app, and the eSIM activated automatically the moment I landed. Hotspot sharing works on every plan, so I tethered my laptop without thinking twice. On my last trip I used that hotspot to work from a cafe in Hoi An through the morning, then booked a lantern boat ride through Hoi An’s ancient town for the evening straight from my phone.

Quick pros and cons
- Cheap entry price and strong value at most data tiers.
- Built-in ad blocker and security features that no rival matches.
- Free hotspot sharing on every plan.
Downside: It does not always state which local network you are on, and coverage thinned out for me deep in the far north!
2. Airalo: the best cheap eSIM for Vietnam (and best for rural areas)
If you want a cheap eSIM for Vietnam without gambling on a no-name brand, Airalo is the safe choice. Its Vietnam plan, called Xin Chao, runs on Viettel, the army-owned network with the widest rural reach in the country. So while it is a budget eSIM Vietnam travelers love for the price, it is also the one I trust most off the beaten track.
Pricing sits a little above Saily per GB. For example, expect around $4 for 1 GB and roughly $20 for 10 GB, plus a 50 GB plan near $49 for long stays. It is not the absolute cheapest on paper, but the Viettel coverage earns that small premium.
Where it really shone was the remote stuff. I held a usable signal across most of the Ha Giang Loop and through the Mekong Delta, places where other eSIMs gave me nothing but a spinning wheel.

Quick pros and cons
- Runs on Viettel, so it has the best rural and mountain coverage of the three.
- A trusted brand with a handy app and loyalty credits.
- Downside: the Vietnam plan is still 4G rather than 5G, and the smallest plan expires quickly.
3. Holafly: the best unlimited eSIM for Vietnam
Some trips just need unlimited data, and that is where Holafly comes in. It sells unlimited plans only, it taps all three Vietnamese networks, and the eSIM arrives by email, so you do not even need an app.
I leaned on them while working remotely from Da Nang. The connection held up nicely, and I never once checked a data counter.
It is the priciest of the three, though. Plans run from about $27 for 7 days to roughly $74.90 for 30 days. Note that it seems that Holafly caps hotspot sharing tightly, so not the optimal fit for heavy laptop tethering.

Quick pros and cons
- Unlimited data
- Email delivery, so no app is required.
- Downside: the highest price of the three
How much data do you actually need in Vietnam?
This trips up a lot of first-timers, so let me keep it simple.
For a week in the cities such as Hanoi and Ho Chi Minh City, with normal Grab, maps, and messaging, 5 to 10 GB is plenty. If you stay two to three weeks and post a lot, lean toward 15 to 20 GB instead. And if you work online or stream every day, just grab Holafly’s unlimited plan and stop counting.
One more tip: download offline Google Maps before any overnight train or boat. Even the best eSIM for Vietnam drops out in the Hai Van Pass tunnels and across parts of Ha Long Bay.
Where these eSIMs let me down
No eSIM is perfect here, and I would rather tell you the truth than sell you a fantasy.
Coverage is the big one. Cities are easy, but Vietnam gets patchy fast once you climb into the mountains or head out to sea. Saily wobbled in the far north for me. Holafly throttled after a few heavy days. Even Viettel-backed Airalo dropped out in deep valleys and long tunnels. So whatever you choose, treat offline maps as non-negotiable.
Hotspot rules also vary. Saily shares freely, Airalo depends on the plan, and Holafly caps it tightly. Therefore, if tethering a laptop matters to you, check the fine print before you pay.
FAQs
Yes. All three major networks support eSIM, so any reputable provider will connect you within minutes of landing.
For the lowest entry price, Saily’s 1 GB plan at $3.99 is hard to beat. That said, Airalo gives you the cheapest reliable coverage once you head into rural areas.
Airalo, because it runs on Viettel, the network with the strongest reach outside the big cities.
Almost never. A Vietnam eSIM keeps your home number live and skips the ID paperwork that a local SIM requires.
So, which is the best eSIM for Vietnam?
If you want one answer, get Saily. It is reliable, cheap, and easy, which is exactly what most travelers need.
Going deep into the mountains or the Mekong, though? Pick Airalo for that Viettel signal. Working online or streaming every day? Holafly’s unlimited data is worth the extra cash.
Whichever you choose, sort it out before you fly. You will step off the plane in Vietnam already connected, and you can spend your first hour booking a tour instead of hunting for a SIM kiosk.
