The Best eSIM for Vietnam in 2026: Why I Use Saily eSIM
Vietnam is for sure one of my favorite countries to explore, from the chaos and street food of Hanoi to the quiet limestone landscapes around Ninh Binh. Waseem and I visited Ninh Binh right after Hanoi for two days and the contrast was apparent. Since we work online full-time as digital nomads, a reliable connection is non-negotiable for us which is why sorting out our eSIM is always the very first thing we do before we fly.
I’ve tested plenty of providers over the years, including Airalo and Holafly and for our trip through Vietnam we went with Saily. In my experience it’s the best eSIM for Vietnam right now, thanks to a great mix of price, coverage, and peace of mind. In this guide, I’ll walk you through how it performed, how it stacks up on price, and how much data you’ll actually need.
What Is an eSIM and do you need one when traveling to Vietnam?
Before we get into the details, here’s a quick primer in case you haven’t used one yet. An eSIM is a digital SIM card that’s already built into your phone, so instead of swapping tiny pieces of plastic, you scan a QR code or tap through an app and you’re connected.
I learned why that matters the hard way when I first traveled to Thailand. I bought a physical SIM from a local shop, and between the language barrier and having no app to keep track of my data, the whole thing turned into a giant headache.
Vietnam has its own version of that hassle, since tourist SIMs usually mean lining up at the airport, handing over your passport to register, and paying in cash. A Vietnam eSIM skips all of that. You buy the Saily eSIM online, install it at home over Wi-Fi, and it activates by itself once you connect to a network in Vietnam, while your regular SIM stays active for calls and texts. That’s a total game-changer when you land and just want to book a Grab, and it’s why an eSIM is the first thing I sort out now.

Why Saily Is My Pick for the Best Vietnam Travel eSIM
After trying a bunch of other travel eSIMs throughout my travels, I settled with Saily and I couldn’t be happier. I judge every eSIM on the same four things: affordability, coverage, internet speed, and how easy the app and setup are. Here’s how Saily did on each one, and why it earns my vote as the best Vietnam travel eSIM.
Affordability
I started out as a budget backpacker, so I’m still kinda frugal and the price tag is one of the first things I check. Saily’s Vietnam plans start at $3.99 for 1 GB (valid for 7 days) and go up to $28.99 for 20 GB (valid for 30 days), and the bigger the plan, the cheaper each gigabyte gets. There are unlimited plans as well, running from 5 to 30 days. We bought the 10 GB (valid for 30 days) plan and paid $17.99 for it.
I’ll be honest, Saily isn’t the cheapest eSIM for Vietnam at every plan size. But it’s consistently competitive, it’s prepaid so there are no surprise bills, and you get 3% back in Saily credits, which adds up to serious bang for your buck.
Great Coverage
This is where Saily really won me over, and it’s the factor that matters most when you’re picking the best eSIM for Vietnam. Ninh Binh is only about 90 km south of Hanoi, but once you leave town it’s all countryside, with rice fields, rivers, and limestone hills in every direction. That’s exactly the kind of place where some eSIMs get patchy, yet my Saily connection was really good out there and I never had my internet drop, not even once. We went on the Trang An boat tour and were surrounded by towering limestone karsts. We also climbed the 500 steps to the dragon at Hang Mua and service was still great.
Coverage always depends on the local networks, and Saily itself says it’s strongest in big cities like Hanoi and Ho Chi Minh City and along the main tourist routes. It also notes that signal can vary in mountain regions like Sapa and Ha Giang, so if you’re heading up there, I’d download offline maps as a backup. We also downloaded offline maps for Ninh Binh but never used it once since we always had connection.
The built-in security features are a nice bonus too. Saily comes from the team behind NordVPN, and the app includes web protection that helps block malicious sites, an ad blocker that Saily says can cut data usage by up to about 29%, and virtual locations. For someone who lives online like I do, that extra layer is a big plus.
Good Internet Speed
Most days my laptop doubles as my office, so I’m jumping on video meetings, taking partner calls, sending documents, and making quick edits from wherever I’ve set up for the day. A slow connection just isn’t an option for that. Saily runs on local carriers and supports 3G, 4G, LTE, and 5G depending on your location, and I got fast 4G and 5G nearly everywhere I traveled in Vietnam. It was steady enough to unwind with Youtube streaming or a Netflix movie on my unlimited plan too, and nothing ever froze or stalled on me.
Easy Setup + App
I’m very much on team no headaches when I travel, and Saily fits right in. You download the app, pick your plan, install the eSIM, and it activates automatically once you connect in Vietnam. You also get 30 days after purchase to activate it, so there’s no rush. Just make sure data roaming is switched on for the eSIM, since that’s the most common reason people see full bars but no internet. If you get stuck, there’s 24/7 live chat support. I was still packing for Vietnam when I remembered I hadn’t gotten my eSIM yet. It took me two minutes to buy and set up my eSIM the night before our flight. Simple and fast.

Saily Vietnam eSIM Prices & Plans
I’ve looked at more providers than the four below, but these are the ones most travelers end up comparing, so I lined them up side by side. Prices are for a 15-day unlimited plan, the format most people want when they’re hunting for the best unlimited eSIM for Vietnam, and they were checked in September 2026, so double-check current rates before you buy.
| eSIM provider | Duration | Price | Speed / fair-use policy | Hotspot | Extras |
|---|---|---|---|---|---|
| Saily | 15 days | $48.99 | 4G/5G where available; 5 GB/day at full speed, then unlimited data at up to 1 Mbps until the next daily reset. | Yes; no separate hotspot cap (tethered data counts toward the 5 GB/day). | Ad blocker, web protection, virtual location; data-only plan (no local calls/SMS). |
| Airalo | 15 days | $49.00 | 4G/5G where available; 3 GB/day at full speed, then unlimited data at up to 1 Mbps until the next daily reset. | Yes; unlimited tethering, but it draws from the same daily 3 GB high-speed allowance. | Data-only plan; no stated security bundle. |
| Holafly | 15 days | $50.50 | 4G/5G where available; unlimited data, subject to Holafly’s fair-use policy. No fixed daily full-speed allowance is published for Vietnam. | 1 GB/day hotspot limit. | Always On: 1 GB backup data every 30 days while the eSIM remains installed. |
| Ubigi | 15 days | $39.90 | 5G where available; 30 GB total at full speed, then unlimited data at 2 Mbps for the remainder of the plan. | Yes; hotspot supported with no separate cap (all usage, including tethering, counts against the 30 GB then 2 Mbps limit). | Data-only eSIM; fair-use threshold applies to the entire 15-day plan, not per day. |
Every provider here will get the job done, and I’m not here to trash anyone. I’ll even be upfront that Ubigi comes in cheaper for a 15-day unlimited plan. Still, Saily wins for me thanks to the built-in security features, the flexible plan lengths, and a connection that never let me down in the countryside, which adds up to the best overall value.

How Much Data Do You Need for a Vietnam eSIM?
It depends on your travel style. Are you doing a quick trip to Hanoi and Ninh Binh? Hopping down the coast for a few weeks? Or working from cafés for a month? Answering that makes picking a plan much easier.
For shorter trips, a fixed plan is usually plenty. Saily’s 1 GB plan ($3.99) can cover a quick visit, while the 5 GB ($10.99) and 10 GB ($17.99) plans, both valid for 30 days, suit a couple of weeks of maps, Grab rides, and messaging. As a rough guide, that kind of use burns 300 to 600 MB a day, and Saily has a data usage calculator on its site if you want your own estimate.
For longer trips or heavier use, I’d go unlimited, since I’d always rather have it and not need it than need it and not have it. If you’re hotspotting to your laptop, uploading photos, or streaming when the hotel Wi-Fi crawls, that’s when the best unlimited eSIM for Vietnam pays for itself. Saily’s published daily cap is 5 GB before speeds slow down, which is roomier than Airalo’s 3 GB.
FAQs About the Best eSIM for Vietnam
What is the best unlimited eSIM for Vietnam?
For me, it’s Saily. It never dropped on me in the countryside, it offers unlimited plans from 5 to 30 days so you can match your trip, and its daily cap is on the generous side. If you only need a few gigs, though, a fixed plan will save you money.
Who should get a Vietnam eSIM?
Honestly, almost anyone visiting Vietnam. A local SIM means registering with your passport and often waiting in line, while an eSIM is ready before you leave home. The only people who can skip it are those whose home plan already covers Vietnam at a fair price, and just make sure your phone supports eSIM first.
Should I get an eSIM or a SIM card?
Get the eSIM. A physical SIM can be cheaper, but between passport registration, airport lines, and having no app to check your data, it’s more hassle than it’s worth, and I’ve been through that routine myself in Mexico. With Saily, you can even keep your regular SIM active for calls and texts.
What is the cheapest eSIM for Vietnam?
If you’re after the cheapest eSIM for Vietnam on a short trip, Saily’s 1 GB plan at $3.99 (valid for 7 days) is about as cheap as it gets among the big names. On bigger plans, competitors like Ubigi can come in lower, so if pure price is your priority, compare before you buy. For me, a connection that never dropped was worth it.
Final Thoughts on the Best eSIM for Vietnam
I’ll keep this one short. Most eSIM providers out there are solid, and it really comes down to the best balance of price and value for your trip. For me, that was Saily: a connection that stayed strong in the countryside and never dropped, an easy setup, and built-in security features on top.
We also used Saily on our three-week road trip around Japan, and it kept us connected across all those miles too, so it’s not just a Vietnam pick for us. I hope this guide helps you pick the best Vietnam travel eSIM for your own trip, and enjoy Vietnam as much as we did.
