Why You Need an eSIM in Vietnam

Staying connected in Vietnam is more than just a convenience. It can change the way you travel.

First, a travel eSIM saves you time. You don’t need to wait in long lines at the airport to buy a SIM card. You don’t need to show your passport or deal with local registration rules. You just scan a QR code, and you’re online in minutes.

Second, it keeps you safe. Vietnam is a busy country. Streets are full of motorbikes, and cities can feel overwhelming. With an eSIM, you always have access to maps, ride-hailing apps, and translation tools. You can quickly check routes, order a Grab, or ask for help online.

Third, it gives you freedom. Many eSIM plans cover not only Vietnam but also nearby countries like Thailand, Cambodia, or Singapore. If you plan to visit more than one country, you can use the same eSIM. No need to swap cards or carry tiny plastic SIMs in your wallet.

Finally, it is budget-friendly. Traditional roaming can be very expensive. Local SIM cards are cheaper, but they take effort to buy and set up. eSIMs often offer clear pricing and flexible plans. You can choose how much data you need and pay only for that.

So, if you want a smooth trip in Vietnam, a travel eSIM is the smart choice.

How we rated our eSIM for Vietnam results

Not all eSIMs are the same. To get the best experience in Vietnam, you should look at a few key things.

Coverage in Vietnam

Good coverage is the most important factor. Some eSIMs work with only one local operator. Others connect to several. The more networks you can access, the better chance you have to stay online in both cities and small towns.

Network speed

Vietnam has strong 4G and LTE networks in most places. In big cities like Hanoi or Ho Chi Minh City, you may even find 5G. But not every eSIM connects you to the fastest option. Always check if your provider supports 4G LTE or 5G. A faster network means smoother video calls, quicker uploads, and less waiting time.

Price

Travel eSIMs come with many plan sizes. Some give you only a few gigabytes for short trips. Others have larger packages for longer stays. Compare prices carefully. Look at how much data you get and how long the plan lasts. Cheaper is not always better if the data runs out too soon.

Ease of use

Installation should be simple. The best providers let you scan a QR code and activate the plan in minutes. Some require you to download an app and set up everything by hand, which takes more effort. If you want a stress-free trip, choose a provider with QR code support.

By checking these points—coverage, speed, price, and ease—you can find the eSIM that matches your travel style and budget.

Best eSIM for Vietnam in 2025: detailed guide

Here’s the overview of the best eSIMs that actually work in Vietnam, you can compare prices, features, and pick the one that fits your trip best.

1.esimNB - most reliable eSIM for Vietnam

✅ Responsive customer support

✅ Supports over 140+ countries

✅ Plans start from $3.50

✅ No App download needed

esimNB is the best eSIM for Vietnam in 2025, with affordable plans that start from 1GB data 7 days, for $3.50, which is cheapper than other competitors. Anything beyond that will last you for up to 30 days and varies from 3 GB for $8.50, to 20 GB for $32.00.

esimNB works with the major mobile operator in Vietnam: Vinaphone, Vietnamobile (with wide coverage across the country, especially in large cities and eastern regions.). This ensures you get the same reliable internet experience as using a local SIM card.

The esimNB homepage is very user-friendly. You can easily find the FAQ section, step-by-step installation guides, and a complete list of compatible devices. After purchasing, simply go to the “My eSIMs” page, where you can clearly check your order details, remaining data balance, and validity period. A step-by-step guide is also available to make installation easy.

2. Holafly- eSIM provider with unlimited data plans

Holafly is well known for offering unlimited data plans, which is a huge advantage for heavy data users. If you often rely on Google Maps for navigation, upload photos or videos during your trip, or even use your phone as a hotspot for work, having unlimited data can make your travel much smoother.

However, for short trips where your data needs are lighter, a fixed data plan can sometimes be a better choice. Flexible plans with set data limits are usually more affordable and help you avoid paying for data you may never use.

It’s also important to keep in mind that “unlimited” does not always mean truly without limits. In many cases, once you reach a certain amount of data usage, your speed may be reduced. While basic tasks like browsing or messaging may still work, activities such as streaming or video calls can become frustratingly slow. That’s why it’s a good idea to weigh your personal travel habits and needs before choosing Holafly.

3. Nomad - another option for Vietnam eSIM

Nomad is another option for Vietnam eSIM users. One limitation, however, is that activation requires downloading the Nomad app, which may not be as convenient for everyone.

In terms of pricing, Nomad is generally a little expensive. For the best value, it’s recommended to purchase during promotion or discount periods, when the cost becomes even more competitive.

4. Gigsky- provide bulk eSIM sales choice

Gigsky is a global eSIM provider with an impressive coverage range. Not only can you buy an eSIM for Vietnam, but you can also access their services in many other countries and regions. What makes Gigsky stand out is its support for maritime connectivity. They even offer eSIMs designed for yachts and vessels, making it possible to stay connected at sea—a valuable feature for frequent travelers and business professionals.

New users also get an extra perk: 100MB of free data. This trial allows you to test the network quality before committing to a larger plan, which is especially helpful if you’re new to using eSIMs.

On top of that, Gigsky provides bulk purchase options for travel agencies, corporations, or any organization needing multiple eSIMs. This not only brings down the cost per plan but also simplifies management for teams traveling abroad or employees on business trips.

Overall, Gigsky is a versatile provider that works well for both individual travelers and enterprise clients, offering wide coverage, flexible options, and unique features you won’t find everywhere.

5. Airalo- eSIM provider with good UI/UX

Airalo is one of the most established eSIM providers and has built a solid reputation worldwide. One of its biggest strengths is its user-friendly guides and step-by-step tutorials, which make it especially helpful for beginners who are using an eSIM for the first time. Whether you’re browsing through the website or using the app, the interface is clean, simple, and easy to navigate, so you can activate your plan without any hassle.

In Vietnam, Airalo partners with two major local operators: Viettel and VNPT. Both networks are known for their reliable coverage and strong performance, giving you a smooth 4G experience across most cities and popular tourist spots.

That said, Airalo’s prices are sometimes higher compared to newer competitors. However, when it comes to Vietnam, the plans are still reasonably priced. If you’re a first-time eSIM user who values simplicity, clear instructions, and reliable service—and you don’t mind paying a little extra—Airalo is one of the best choices available.

Why choosing an eSIM for Vietnam is hard

Finding the right eSIM for Vietnam is not as easy as it sounds. Many websites you see online are run by affiliate marketers. They earn money every time you buy through their links. While some still try to be fair, many focus more on sales than on giving you the full picture. This makes it hard to know if their advice is really in your best interest.

Another challenge comes from review platforms. Sites like TrustPilot let anyone leave a review without checking if they actually used the product. This opens the door to fake positive reviews from sellers or even fake negative reviews from competitors. In the end, you cannot fully trust what you read there.

Because of these issues, travelers often feel lost. You want a simple answer to “which eSIM works best in Vietnam,” but instead, you face a mix of sales talk and unreliable reviews. That is why making the right choice takes extra care.

How do I know if my device is eSIM-compatible

To find out if your device is eSIM-compatible, you can check directly in your phone’s settings:

For iPhone users:

Open the Settings app Go to General > About Scroll down and look for Available SIM or Digital SIM If it appears along with an IMEI number, your iPhone supports eSIM

For Android users:

Open your Settings Tap Network & Internet (this may be listed slightly differently depending on your phone) Select Mobile Network If you see an option like Add SIM or Download SIM, your phone likely supports eSIM functionality
