The eSIM I Actually Use in Vietnam
I've used Airalo across Paris, Singapore, Shanghai, and Hong Kong, and today it's my everyday mobile data here in Da Nang. Here's exactly how I use it, why I recommend it, and what to know before you land.
Airalo eSIM $3 Off Code RYAN6986 Get eSIMGet Set Up Before You Land
Download Airalo well before you land, claim the $3 coupon with code RYAN6986, and buy any Vietnam eSIM package while you're still on solid wifi at home.
That way, the moment your wheels touch down, your phone is already connected and you can order a ride out of the airport without hunting for a signal first.
Of the eSIMs I've Tried, This Is the One I Keep Using
I've tried a handful of eSIM providers while traveling, and Airalo is the one I keep coming back to. Not because it's flashy, but because of the boring stuff that actually matters when you're relying on it daily: the connection holds up, the app doesn't fight you, top-ups take seconds, and support has never left me stuck.
This isn't a product I tested for a weekend to write an affiliate post. I've used it as a traveler in Paris, Singapore, Shanghai, and Hong Kong, and today it's the service that keeps my phone connected day to day here in Da Nang.
Your eSIM Can Be Your Backup Office
Airalo has saved me more than airport hassle. More than once I've needed to work while traveling with no reliable wifi in sight, a slow hotel connection, a cafe with a login screen that never quite works. Because my phone already had Airalo data running, I turned on my hotspot, connected my laptop, and kept working.
If you work remotely, mobile data isn't just for Google Maps and Instagram. It can quietly become your backup internet connection when the wifi you were counting on doesn't come through.
Install It Before You Fly
The single most useful piece of advice in this guide
Download Airalo and buy your Vietnam eSIM before you leave home, not after you land. When you prepare it in advance, you skip the entire first-annoyance of arrival: hunting for airport wifi, standing in a SIM-card line, finding a telecom kiosk, popping out your physical SIM, and trying to download an app on a connection that barely works.
Instead, you land, enable the eSIM, and connect. That's it.
One of my favorite small moments in international travel is watching the plane touch down, cellular service appear on my phone, and immediately being able to receive messages, check a map, text family, order a car, or just see what's happening online. That's a very different arrival than landing somewhere unfamiliar and spending your first twenty or thirty minutes sitting on an airport bench trying to get connected.
Traveling Somewhere with Restricted Internet?
This matters even more in destinations where certain websites, apps, or app stores can be harder to access after you arrive — mainland China is the clearest example, and I've personally used Airalo while traveling in Shanghai.
I won't claim an eSIM bypasses every restriction or gets around a national firewall — it doesn't, and I'm not going to promise something I haven't verified. What I can say is this: install the Airalo app, buy your package, and finish setup before you enter a destination where access to certain services may be limited. That removes the risk of discovering, after arrival, that something you needed for setup wasn't reachable.
Set up the app, install the eSIM, and confirm it's active while you still have your normal internet connection at home. Don't leave it for the layover.
RYAN6986 for $3 offThe More I Travel, the More Airalo Pays for the Next Trip
Every purchase earns Airmoney, credit toward your next eSIM. It's a simple loyalty structure, but it adds up faster than I expected once I started traveling regularly. I eventually reached Platinum, which earns 10% back on every purchase — enough that accumulated credit has covered a meaningful chunk of more than one later trip's data plan.
Tier names, thresholds, and cashback rates reflect Airalo's published loyalty program as of this writing and are set by Airalo, not by us — confirm current terms in the app before relying on them.
My own account, Platinum tier.
When It Doesn't Just Work, Someone Actually Helps
Every time I've run into an issue, I've been able to reach a real person through chat inside the app. Support has asked me for screenshots of my settings and walked me through fixing it step by step. I won't claim every interaction is instant, but I've never been left stuck.
This matters more than it sounds like it should, because most eSIM problems aren't actually network problems. They're settings problems:
When you're standing in another country and just want your phone to work, having someone guide you through those settings instead of a support ticket queue is worth a lot.
How Airalo Works
Which Vietnam Plan Should You Buy?
Airalo's data packages and prices change often enough that I'm not going to hard-code numbers here that could be stale by the time you read this. Instead, think about which of these you are:
Maps, Grab, messaging apps, occasional browsing. A short trip with the phone mostly used for logistics.
Social media, maps, restaurant research, messaging, and moderate photo and video use throughout the day.
Hotspotting a laptop, video calls, frequent uploads, and heavy social media. Budget a noticeably larger package.
A quick note on hotspotting: connecting a laptop through your phone's hotspot uses data significantly faster than phone-only use. If you plan to work from your hotspot at all, size up.

Working data from the moment you land changes the shape of your first day. Most visitors want to order a Grab right after clearing arrivals — that alone is dramatically easier with cellular data already active instead of hunting for airport wifi first. Beyond that first ride, this is what I actually use mobile data for day to day:
If you're planning your first few days in the city, the first-time visitor guide and Da Nang itinerary are good next stops, and if you're working remotely during your stay, the digital nomad guide covers the rest of the connectivity picture. Heading to Hoi An for a day trip? Same advice applies — your eSIM works there too.
Airalo eSIM vs a Vietnamese SIM Card
I'm not going to pretend Airalo wins every category, because it doesn't. Here's the fair breakdown.
If you're staying long-term or genuinely need a Vietnamese phone number, a local physical SIM can make more sense and is often cheaper. See the Da Nang SIM card guide for that route. For most trips, the convenience of showing up already connected outweighs the savings.
Why I'd Still Recommend It
I travel frequently, and I've tried more than one eSIM option along the way. Airalo is the one I keep using. I value being able to install my data before I arrive, hotspot my laptop when wifi lets me down, watch rewards credit build toward future trips, and reach a real person when something needs fixing.
For someone visiting Vietnam, especially for the first time, I think eliminating the "how am I getting online when I land?" problem before you even board the plane is easily worth the ten minutes it takes to set up.

Is Airalo a good eSIM for Vietnam?
In my experience, yes. I've used Airalo across Europe and Asia, and it's my everyday mobile data provider living in Vietnam. It's not the only eSIM option, but of the ones I've personally used, it's the one I keep coming back to.
Should I buy my Vietnam eSIM before I fly?
Yes. Install the Airalo app and set up your Vietnam eSIM while you still have a normal internet connection, ideally before you leave home. That way your phone connects the moment you land instead of you hunting for airport wifi first.
Does an eSIM replace my regular phone number?
No. An Airalo eSIM adds a second, data-only line alongside your existing SIM. Your normal number, calls, and texts keep working through your primary SIM; the eSIM just handles data.
Can I use an Airalo eSIM to hotspot my laptop?
Yes, most Airalo data plans support hotspotting and tethering. I've used mine as a backup internet connection for laptop work more than once. Just know hotspotting a laptop burns through data noticeably faster than phone-only use.
Is a physical Vietnam SIM cheaper than Airalo?
Sometimes, especially for long stays or if you need a local Vietnamese phone number. For a trip where convenience and keeping your existing number matter more, an eSIM is usually the better trade-off.
