For the traveler who hates worrying about data limits, Holafly is a standout choice. It’s built on a simple premise: truly unlimited data. You know what that means? You can use Google Maps to your heart’s content, upload all those pictures from your Ha Long Bay cruise instantly, and make video calls home without a second thought.
| Established Year | Coverage | Key Features | Data Plans | Network Partners | Customer Support | App Available | Verdict Score |
| 2017 | Vietnam, 160+ Countries | Unlimited data plans, 24/7 support | Unlimited data plans | Viettel, Vinaphone | 24/7 Live Chat | iOS & Android | 9.2/10 |

The Holafly Vietnam experience is designed to be completely hands-off once it’s set up. We found the connection to be very fast and stable in major tourist areas, but it’s important to remember that while the data is unlimited, there can be fair usage policies that might throttle speeds after a certain high-usage threshold. It’s not a deal-breaker, but it’s something to be aware of if you’re a serious streamer.
Holafly stands out for one clear reason: its eSIM Vietnam unlimited data plans. This is a massive relief for anyone who needs to be constantly connected. You won’t have to monitor your data usage, which is perfect for a trip where you just want to relax and explore. The price might be a bit higher than a smaller, data-capped plan, but for the peace of mind it offers, many travelers find it to be a worthwhile investment. Their customer support is also top-notch, available 24/7 in multiple languages, so if you run into any issues, help is just a chat away.

This means you can often choose a plan specifically connected to a network like Viettel, which is known for its strong signal in certain regions.

Nomad gives you the power to choose. We appreciate that their platform lets you see which local networks you’ll be using.

aloSIM is a provider that understands the nuances of international travel. While many eSIMs are data-only, aloSIM has a unique edge: they offer plans that include a local Vietnamese phone number. This is a huge deal for certain types of travelers. Do you need to make local reservations, book tours, or deal with local services? A local number simplifies everything.

This feature is integrated through the Hushed app, so you can make and receive calls and texts through the number provided, which is fantastic for communicating with hotels, tour guides, and local businesses.
The key selling point for aloSIM is the bundled Vietnamese phone number. This makes them an incredible choice for any traveler who needs to communicate locally without using costly international roaming. It’s a fantastic alternative to buying a traditional Vietnamese prepaid SIM card and the setup is far less of a hassle. For a digital nomad or a business traveler, this feature alone could make aloSIM the top choice.

Our goal is to give you a clear, honest picture of what to expect from an eSIM in Vietnam. To do that, we have a very specific process for our evaluations. We believe that by being transparent about our methods, you can have confidence in our recommendations. We don’t just look at pricing; we consider a range of factors that truly impact a traveler’s experience on the ground.
The first thing we check is where and how well an eSIM works. We look for providers that partner with Vietnam’s top-tier local carriers, like Viettel, Vinaphone, and MobiFone. These networks have the most robust infrastructure, meaning you’ll get reliable 4G and 5G connections in major cities like Hanoi and Ho Chi Minh City, but also in popular tourist areas like Ha Long Bay and the Mekong Delta. We also make sure the connection holds up during day trips and while traveling between destinations.
Value for money is a huge factor. We analyze the variety of data amounts and validity periods offered, looking for providers with flexible options that suit different trip lengths and travel styles. We scrutinize the cost, comparing it to what you’d pay for a local Vietnamese SIM card, to ensure you’re getting a good deal. We’re also very particular about “unlimited” plans, looking for transparency regarding any fair usage policies (FUPs) that might slow down your speeds after a certain amount of data is used. This is why we have a detailed look at things like an eSIM Vietnam unlimited data plan.
A good eSIM should be easy to use. Period. We evaluate the entire user journey, from the app experience to the activation process. This includes how simple it is to purchase a plan, whether you need to download a QR code, and how easy it is to set up upon arrival at an airport like Noi Bai International Airport. Clear, simple instructions are a non-negotiable for us.
You hope you’ll never need customer support, but when you do, it should be fast and effective. We check for providers who offer 24/7 support through live chat or other responsive channels. We also look for providers who have multilingual support, as language barriers can be a real issue when you’re in a new country and need help.
Some eSIMs offer more than just data. We look for providers that include useful extras like hotspot capability, or in the case of a few providers, a Vietnam phone number for local calls and texts. These features can be a major convenience and are definitely worth considering when making your choice.
To make your decision even easier, here’s a comprehensive table summarizing the key features of our top 10 recommended providers.

Honestly, an eSIM is a no-brainer for a trip to Vietnam. The days of hunting for a SIM card for Vietnam are thankfully becoming a thing of the past. The biggest advantage is the sheer convenience. You can purchase and set up your eSIM for Vietnam before you even leave home. This means you land at the airport, turn on your phone, and you’re immediately connected. No more fumbling with tiny physical cards, no more looking for a vendor in a crowded terminal, and no more worrying about losing your home SIM card.
Another massive benefit is cost. Using an eSIM card Vietnam is almost always cheaper than international roaming charges from your home carrier. You get local data rates without the hassle of a local SIM. Plus, an eSIM allows you to keep your primary number active for important calls or texts while using the eSIM for all your data needs. This is perfect for using apps like Grab, Google Maps, and WhatsApp without the risk of an expensive phone bill when you get back home.
The eSIM market in Vietnam is constantly evolving. In 2025, we’re seeing some interesting trends that will make connectivity even smarter for travelers. One of the biggest is the move towards AI-powered plan recommendations. Imagine an app that suggests the perfect data plan for you based on your itinerary, travel habits, and budget. We’re also seeing more hyper-localized deals for specific areas, so you might get a special offer for a plan that works best only in the Mekong Delta or the mountainous regions. The expansion of 5G across the country is also huge, promising even faster speeds and more reliable connections. We’re also seeing providers focusing more on digital security and privacy features, which is a big deal when you’re using public Wi-Fi.
When you’re choosing your eSIM for Vietnam, there’s more to consider than just data size and price.
You might wonder how an eSIM gets you connected in Vietnam. Here’s the thing: eSIM providers are not their own mobile networks. They partner with major local Vietnamese networks to give you access to their infrastructure. The biggest players in Vietnam are Viettel, Vinaphone, and MobiFone. These partnerships ensure that your eSIM works seamlessly, getting you a strong signal in cities and on highways. The robust network infrastructure of these carriers is what allows you to have a great connection whether you’re navigating the traffic in Ho Chi Minh City or relaxing on a secluded beach.
To really make the best decision for your trip, it’s good to weigh all the factors. Here’s a quick overview of the overall pros and cons of using an eSIM for Vietnam.
| Pros | Cons |
| Instant connectivity upon arrival at the airport | Not all devices are eSIM-compatible |
| No need to physically swap SIM cards | Data-only plans mean no local number for most providers |
| Cost-effective and avoids expensive roaming fees | Some “unlimited” plans have fair usage policies |
| Keep your home number active for calls and texts | May require a working internet connection for activation |
Before you buy an eSIM for Vietnam, you need to make sure your device supports it. Most newer smartphones, including the iPhone XR and later models, and most recent Android phones (like Samsung Galaxy S20 series and Google Pixel 3 and newer), are eSIM compatible. The best way to check is to go into your phone’s settings and look for an “Add Cellular Plan” option. If you see it, you’re good to go. If you’re not sure, just a quick search on your phone manufacturer’s website will give you the answer.
Purchasing your eSIM for Vietnam is usually as easy as online shopping. Most providers accept all major credit and debit cards, including Visa, Mastercard, and American Express. Many also support digital wallets like PayPal, Apple Pay, and Google Pay for a faster checkout experience. This makes the entire process incredibly smooth and secure.
Let’s break down the classic debate: is an eSIM or a physical SIM better for Vietnam? The choice really comes down to your personal preferences and needs.
| eSIM | Physical SIM | |
| Convenience | Instant, no physical card required, can be bought before the trip. | Requires finding a vendor and swapping cards upon arrival. |
| Cost | Often cheaper than roaming, offers competitive local rates. | Can be very cheap locally, but can be more expensive at the airport. |
| Flexibility | Easy to switch plans or top up with a few taps in an app. | Requires buying a new card or visiting a store to top up. |
| Phone Number | Mostly data-only, though some (like aloSIM) offer a local number. | Comes with a local Vietnamese phone number by default. |
| Compatibility | Requires a newer, unlocked smartphone. | Works with virtually all unlocked smartphones. |
| Risk of Loss | None, as it’s a digital profile. | Your home SIM card can be lost or misplaced during the swap. |
| Installation | Quick and simple, via QR code or app. | Can be a hassle, especially with the small ejector tool. |
For most travelers, an eSIM is the clear winner for its convenience and ease of use. However, if you’re on a very tight budget and need a local number for a very long stay, a local Vietnamese SIM card might be a slightly better option, as you could find a cheap one in a local shop.
When it comes to data plans, providers like Airalo and Nomad offer a range of options, from a small 1GB plan perfect for a weekend trip to a hefty 20GB plan for a month-long backpacking adventure. The eSIM Vietnam unlimited data options from providers like Holafly and Yesim are great for peace of mind, though it’s always good to check the fine print for fair usage policies. In major cities, you can expect fast 4G and even 5G speeds, but in more remote, rural areas, speeds might drop to 3G. This is something to expect from any carrier, local or eSIM.
The right eSIM for Vietnam really depends on your travel style.
Setting up your eSIM for Vietnam is incredibly easy. Here’s a simple, generic guide to follow:
Staying connected is great, but staying safe is even better. While your eSIM provides a secure connection, always be mindful of your online presence. Use strong passwords, be cautious about the information you share on public Wi-Fi networks, and consider using a VPN for an extra layer of security.
After an extensive review of all the options, we can confidently say that Airalo is the overall top-rated eSIM for Vietnam. It strikes the perfect balance of reliability, a wide range of affordable plans, and a user-friendly experience. It’s a solid, dependable choice that works well for every type of traveler.
If you’re ready to get connected without the hassle, Airalo is our top recommendation.
An eSIM is a digital SIM card that’s built into your phone. For Vietnam travel, it means you can download a data plan to your device without needing a physical card. It works by connecting to a local partner network as soon as you arrive, giving you internet access right away.
For most international travelers, an eSIM is better because it’s more convenient. You can set it up before you even leave home, you don’t risk losing your home SIM, and you can keep your primary phone number active. A physical SIM card for Vietnam is only really a good choice if your phone isn’t eSIM-compatible or if you’re staying for a very long time and need a dedicated local number.
Yes, providers like Holafly and Yesim offer eSIM Vietnam unlimited data plans. It’s important to read the details, however, as some plans have fair usage policies that might reduce your speed after you hit a certain data cap.
eSIMs work best in major urban centers like Hanoi, Ho Chi Minh City, Da Nang, and Hoi An. You will also have good coverage in popular tourist destinations like Ha Long Bay and Phu Quoc. In very remote, rural areas, the signal may be less consistent, which is the same for a physical Vietnamese prepaid SIM card.
You can purchase and install the eSIM profile before your trip, but you should only turn on the data plan when you arrive in Vietnam. This ensures that the validity period of your plan doesn’t start until you’re on the ground and ready to use it.
Most travel eSIMs are data-only. However, some providers like aloSIM offer plans that include a Vietnam eSIM with phone number, which is a great feature if you need to make local calls or texts for bookings and reservations.
