Factors to consider when choosing an eSIM for Vietnam
Choosing the right travel eSIM for Vietnam depends on your needs – like how much data you’ll use or how long you’re staying. Asking the right questions upfront can help you avoid slow speeds, hidden fees, or limited coverage. Here are the key things to consider before picking a provider:
- Network coverage in Vietnam. Make sure the eSIM provider offers strong coverage in the regions you'll be visiting. Some providers work globally, while others only support certain countries – always check that Vietnam is included and well-covered.
- Your data needs. Think about how you’ll use your data. Light browsing and messaging don’t need much data, but streaming, video calls, or working remotely will eat through it quickly. Estimate your needs based on your usage habits.
- Trip duration. eSIM plans come with fixed validity periods – some last a few days, others up to a few months. Choose a plan that covers the full length of your trip to avoid running out midway.
- Communication needs. Decide if you’ll rely on messaging apps or need traditional calls and SMS. Some eSIMs include voice and text, while others are data-only.
- Tethering support. If you plan to use your phone as a hotspot, ensure the eSIM allows tethering. This way, you can share your internet with your other devices or friends and family.
- Ease of activation. Look for providers that offer quick and simple activation, like scanning a QR code or installing via an app. The less time spent setting up, the more time you have to enjoy your trip.
- Reliable customer support. Responsive customer service can be a lifesaver if you're new to eSIMs or run into issues abroad. Choose a provider with clear support channels and decent reviews.
- Budget and value. Set aside part of your travel budget for mobile data. Prices vary depending on data, duration, and features, so compare a few options to find the best deal without overpaying.

1. Saily – most reliable eSIM for Vietnam
| Rating: | |
| Plans in Vietnam: | 5 |
| Countries/locations: | 200+ |
| Compatibility: | iOS and Android |
| Pricing: | From $3.79 |
Saily is an eSIM provider from NordVPN, a name I’ve trusted for years when it comes to online security. What impressed me most is how it combines solid, affordable data plans with extra security features like a virtual location, ad blocker, and web protection – things you don’t usually get with eSIMs. For traveling in Vietnam, it gave me both peace of mind and smooth, fast connectivity, making it my top pick.
Plans and pricing. Saily offers five different plans for Vietnam. Prices start from $3.79 for 1GB, valid for seven days. You can alternatively get monthly deals or opt for global or regional plans.
| Data allowance | Duration | Price |
| 1GB | 7 days | $3.79 |
| 3GB | 30 days | $8.54 |
| 5GB | 30 days | $11.39 |

Coverage and speed. Saily guarantees reliable coverage by partnering with Vietnam’s top local carriers, so you're always connected to the strongest available network. In my experience, I had smooth 4G and even 5G in major cities like Hanoi and Ho Chi Minh City, with solid speeds for streaming and video calls. Depending on your location, Saily supports 3G, 4G, LTE, and 5G connectivity.
My experience with Saily. Activating my Saily eSIM was quick and stress-free. I downloaded the app, signed up – no ID verification needed – and picked a Vietnam plan in just a few taps. The app is clean and easy to navigate, and everything was ready to go before my trip. Just make sure to activate it while you still have internet access.
Whenever I needed help, I could count on Saily’s 24/7 support through their help center – they were responsive and easy to reach. I got the answers I needed in a matter of minutes.
2. Airalo – eSIM for multi-stop travel
| Rating: | |
| Plans in Vietnam: | 6 |
| Countries/locations: | 200+ |
| Compatibility: | iOS and Android |
| Pricing: | From $4.50 |
Airalo has been a solid choice for my travels through Vietnam, but what really makes it stand out is how well it works across multiple countries. It’s perfect if you're planning a multi-country trip, with flexible regional and even global plan options depending on where you're headed. I found it super convenient not having to switch providers every time I crossed a border.
Plans and pricing. Airalo currently offers local, regional, and global plans. You can check local plans for Vietnam or regional plans for Asia. For Vietnam, Airalo has six local eSIM plans. Plans and their capacity change depending on the validity period.

Coverage and speed. If you're only visiting Vietnam, Airalo’s local plan does the job. The provider usually offers a 4G connection with solid coverage throughout the country. However, if you’re planning to visit multiple countries this year, I’d recommend checking out their global plans instead.
My experience with Airalo. Getting my Airalo eSIM set up was simple and hassle-free. I activated it through the app, though you can also use a QR code if you prefer. Just keep in mind that Airalo requires ID verification, so it’s a good idea to allow some extra time for that step before you travel.
Anytime I ran into an issue, Airalo’s support was just a message away – available around the clock through chat, email, and help centers. Getting assistance was fast and straightforward.
3. Jetpac – reliable eSIM for saving money in Vietnam

| Rating: | |
| Plans in Vietnam: | 6 |
| Countries/locations: | 200+ |
| Compatibility: | iOS and Android |
| Pricing: | From $4.50 |
aloSIM offers both local and regional plans, but what stood out to me was the option to get a temporary local phone number for calls and texts. It made staying in touch while in Vietnam much easier, especially when I needed to make quick local calls or receive messages without relying on Wi-Fi. In my opinion, that’s the best Vietnam eSIM with a phone number.
Plans and pricing. While aloSIM doesn’t offer global plans, it does have local and regional ones. There are six plans for Vietnam. Their pricing starts from $1.00/GB for 7 days. You can also get an unlimited 10-day plan for $38.00.
| Data allowance | Duration | Price |
| 1GB | 7 days | $4.50 |

They’ve got 24/7 live chat and some solid guides, but I found their support a bit less intuitive compared to what I experienced with Saily or Airalo.
5. Nomad – best-priced Vietnam eSIM for larger data packs
| Rating: | |
| Plans in Vietnam: | 5 |
| Countries/locations: | 200+ |
| Compatibility: | iOS and Android |
| Pricing: | From $6.00 |
Nomad turned out to be a really user-friendly eSIM option during my time in Vietnam. What I liked most was the flexibility – they offer local, regional, and global plans, and you can even customize your data package based on how much you actually need. If you use a lot of data like I do, their larger data packs are a big plus, especially at such reasonable prices.
Plans and pricing. Nomad has local, regional, and global plans available for use in Vietnam. There are five plans you can choose from. The validity period of the plans ranges from 7 to 45 days. Plans that have the same validity period offer different speeds.
| Data allowance | Duration | Price |
| 1GB | 7 days | $6.00 |
| 3GB | 30 days | $10.00 |

| 10GB | 30 days | $16.00 |

Coverage and speed. Nomad offers 4G in Vietnam. However, I found that the speed highly depends on your chosen plan, location, and time of the day.
My experience with Nomad. What I appreciated about Nomad eSIM was how simple the activation process was. There’s no need for identity verification – just scan the QR code and follow the prompts. As long as you’re connected to the internet, the eSIM installs in minutes and is ready to use.
If I ran into an issue, I could reach out to Nomad through their help center or shoot them an email – both options were available. Their FAQ section came in clutch with clear, detailed info.

GigSky nails it for business travelers thanks to its consistent coverage, super simple app, and polished, professional feel. Like other providers on my list, it covers over 200 countries and ensures reliable data. I found it a smart pick if you want dependable connectivity with a smooth user experience.
Plans and pricing. What I appreciate is that GigSky offers a free 7-day plan with 100MB to test the waters. If you like the service, you can get its cheapest 7-day plan for $4.99/GB. Also, it offers a variety of unlimited data plans from $4.99 for different durations.

Coverage and speed. GigSky eSIM’s connection works through a network of local telecom providers, such as Vinaphone and Viettel, providing 3G, 4G, and up to 5G speed in major cities and tourist places.
My experience with GigSky. Setting up GigSky was fast and frictionless. I downloaded the app, created an account, and picked a plan, all in just a few taps. The eSIM installed directly through the app without needing to scan a QR code, and since there’s no ID verification, I was ready to go as soon as I landed.
GigSky provides support through email and in-app chat, usually responding promptly. However, many users have mentioned delays when they needed urgent help.
7. Holafly – customizable unlimited data plans across Vietnam
| Rating: | |
| Plans in Vietnam: | 90 |
| Countries/locations: | 200+ |

If you’re after unlimited data without the stress of tracking usage, Holafly is easily one of the top picks. I found it especially useful in Vietnam, where it offered full coverage and let me customize the plan length to match my trip. No throttling, no guesswork – just smooth connectivity wherever I went.
Plans and pricing. Holafly eSIM offers plans for unlimited data in Vietnam that begin at $1.99 for 1 day. Simply choose the number of days, and the price will adjust accordingly. Keep in mind that this eSIM works only with data, meaning you won't get a local phone number for calls or texts.

| Unlimited | 7 days | $29.90 |
| Unlimited | 15 days | $50.90 |

Coverage and speed. Holafly partners with leading local networks like Viettel, Vinaphone, and Mobifone, ensuring 3G, 4G, and 5G internet speeds. Given the unlimited nature of Holafly's data plans, the speed you receive will apply to fair use policy; so, you might be seeing the speed drop some time after heavy usage.
My experience with Holafly. Activating Holafly was quick and stress-free. I didn’t need to download an app or verify my identity – just scanned the QR code they sent and followed the setup steps in my phone’s settings. I had everything ready before landing in Vietnam, and the connection kicked in right away. However, keep in mind that there's an ongoing discussion on Reddit about Holafly routing its traffic through China. It may raise some privacy concerns if you really care about how your data is handled.
They provide support in multiple languages – including English, French, and Spanish – through live chat, email, and a comprehensive FAQ section.
8. Roamless – long-term data plans for Vietnam

I liked how easy it was to pick a plan based on my actual usage for the whole month.
Plans and pricing. Like GigSky, Roamless offers a free 30-day plan with 450MB. Paid plans begin at $3.95/GB for 30 days. A big plus for Roamless is that it provides a plan with global coverage, meaning you could purchase one eSIM that would operate in several countries.

Roamless provides customer support via live chat and email, but their service isn’t guaranteed 24/7, which can be challenging for travelers needing help at odd hours.

How we tested and ranked these eSIM providers for Vietnam
I went through 11X of eSIM providers to find the top picks for traveling in Vietnam. To make sure these options are solid for travelers, digital nomads, and remote workers, I focused on pricing, user experience, data plans, and device compatibility. Here’s what I looked at when ranking them:
- Coverage in Vietnam (25%). Vietnam has a mix of urban and rural areas, and network coverage can vary by region. I prioritized eSIM providers that offer broad, reliable coverage across the country. I also checked which local telecom networks each eSIM partners with to ensure solid 4G, LTE, and 5G access.
- Network (25%). Fast internet is paramount when mapping, video calling, or streaming. I picked eSIMs with a minimum of 4G and LTE; some providers even offer 5G. I also considered network stability and roaming agreements with the most prominent Vietnamese carriers, such as Viettel, Vinaphone, and Mobifone.
- Data plans (15%). Mobile data needs vary from traveler to traveler. Some just browse occasionally, while others rely on unlimited data for work, socializing, and streaming. I included eSIM providers that offer short-term plans ranging from 1 to 7 days, as well as longer options lasting 30 to 90 days. Regional and global plans were also taken into account.
- Ease of use (15%). eSIM installation and activation should be straightforward. Some providers use QR codes, while others rely on app-based activation. I evaluated each provider’s setup process, giving preference to those that keep things simple and don’t require identity verification.
- Price (10%). Pricing varies depending on data allowances, validity periods, and different levels of network quality. I calculated each provider's cost-per-GB to determine which gives the best value without hidden fees.
- Compatibility (10%). Most modern devices – smartphones, tablets, and smartwatches – support eSIMs, although some providers restrict them to specific brands or models. I chose eSIMs compatible with most iPhones and Android phones.
Benefits of using eSIM in Vietnam
On my trip to Vietnam, I found eSIMs to be essential for travel. It’s not just about avoiding expensive roaming fees – they also offer a level of convenience and flexibility that traditional SIM cards can’t match. Here’s why I keep choosing eSIMs every time I travel:
- Instant activation. You can activate your eSIM online and get connected right away without waiting in line or visiting the store. Some eSIMs even activate automatically upon arrival to the destination, so you’ll be able to use it as soon as you land.
- No physical SIM needed. Since the eSIM is software-based, you don’t need to switch physical SIM cards. That also means no risk of losing or damaging it.
- Easy switching between plans. You can manage multiple plans or carriers on one device and switch between them. It’s very convenient for balancing local and international coverage without swapping SIMs.
- Avoid roaming charges. Using an eSIM, you can dodge expensive roaming fees from your home carrier. You can stay connected with fast speeds without breaking the bank.
- Multiple profiles. You can store several eSIM profiles on your device at once. That means you can switch between different numbers or data plans depending on your travel needs.
- Secure and reliable. eSIMs are built into your device, making them harder to lose or tamper with. Also, they connect to trusted local networks for stable, secure service throughout your trip.
Things to know about using an eSIM card in Vietnam
I’ve been using an eSIM for all my travels, and over time I’ve gathered some tips and tricks to help you on your way to Vietnam. From activation to managing your data, understanding how eSIMs work in this country will help you stay connected without any surprises. Here’s a quick guide to help you navigate eSIMs:
- Activate your eSIM before landing in Vietnam. This way, you’ll have a seamless connection as soon as you arrive. Activating early also helps avoid any setup issues in an unfamiliar place.
- Turn off roaming on your main SIM card. This prevents accidental roaming charges that can quickly add up. It also helps your phone prioritize the eSIM connection for better service.
- Save data by downloading offline maps. Offline maps work without the internet, so you won’t waste precious data on navigation. It’s a smart way to stay on track, especially in areas with spotty coverage.
- Know how to track your data usage. Use your eSIM provider’s app or your phone’s built-in data monitor to avoid running out unexpectedly. Staying aware helps you manage your plan efficiently and avoid surprise costs.
