Best eSIM for Vietnam: Which one to choose in 2025?

Golden Bridge in Ba Na Hills, near Da Nang, held by giant stone hands, is one of Vietnam’s most Instagram-worthy spots. Tickets often sell out quickly. The most secure way to access this and many other attractions is to book them online. Without a  Vietnam eSIM with reliable internet, you could miss your chance or rack up your bill using your primary SIM data.

In this article, we’ll review the offers of many eSIM providers and their Vietnam eSIMs, so you can choose the best one for your trip.

Why should I get an eSIM for Vietnam?

If you don’t need a local phone number, and you are OK with making your phone calls with WhatsApp, FaceTime and similar apps, eSIM packages are your best option. Here’s why a data tourist eSIM is the way to go:

• Better than physical SIM card: Avoid the hassle of registering for a local SIM card, providing ID, or dealing with limited tourist SIM options that may not always allow top-ups.
  
• Convenient setup: All eSIM compatible devices allow you to activate your eSIM instantly and start using your eSIM data plan without searching for SIM card stores or handling an additional physical SIM card.
  
• Essential for travelers: Use reliable mobile data to navigate with Google Maps, translate with language apps, or book accommodations on the go.
  
• No expensive roaming: Get affordable, local network access and use a mobile data plan without the hefty data roaming costs.
  
• Flexible plans: Your eSIM plan’s duration and data allowance can be tailored to your trip, from short to extended stays.

Top eSIM providers for Vietnam

Not all eSIMs are created equal, and their pricing, data limit, ease of use, and other features can differ from one provider to another. 

To make things easier for you, we’ve compiled a list of some of the best eSIM providers and their plans for Vietnam. Here they are at a glance before we dive deeper into the details of their offers.

1. Holafly

Holafly is one of the most popular eSIMs for Vietnam, thanks to its solid coverage in the country and the fact that it offers exclusively unlimited eSIM data plans. With Holafly, you don’t need to constantly monitor your data usage or worry about running out at the worst time.

Key features

Holafly aims to make connectivity easy, affordable, and flexible — just like the best trips. Getting a Vietnam eSIM from Holafly is supposed to make travel easier and not more complicated. This is what you can expect from this eSIM provider:

• Data only eSIM with no data cap plan for worry-free usage
• Flexible data plan durations from 1 to 90 days to suit any trip length
• Instant activation via QR code or the Holafly app for iOS and Android
• Regional Asia eSIM covering 12 countries for multi-destination travel
• 24/7 multilingual customer support with email assistance and a searchable knowledge base
• Excellent 4.6/5 rating on Trustpilot based on roughly 50,000 user ratings
• 500 MB per day available for hotspot

Plans and prices

Holafly’s pricing is straightforward and you get to choose how many days your plan will last. The more days you choose, the better the daily rate you get. Here are some of the prices for the most popular data plans:

• 1-day plan: $6.90 USD 
• 7-day plan: $29.90 USD ($4.27 USD/day)
• 15-day plan: $50.90 USD ($3.39 USD/day)
• 30-day plan: $74.90 USD ($2.50 USD/day)
• 90-day plan: $139.90 USD ($1.55 USD/day)

Payment options include credit/debit cards, PayPal, Apple Pay, and Google Pay.

The only downside is that Holafly’s Vietnam eSIM service doesn’t offer phone call or SMS messaging functionality like your usual SIM card. That’s standard for eSIM providers, and you’ll rarely find an international Vietnam eSIM that offers these services.

That said, you can use the internet to send messages and make calls through WhatsApp, Viber, or Messenger, so it’s only an issue if you need a SIM card with a Vietnamese phone number.

2. GigSky

GigSky has been in the eSIM game for a while, and it’s one of the more popular options for those looking into eSIMs for Vietnam. It’s best for very light internet users who need eSIM to handle minor tasks. 

If you use a good portion of your cellular data plan or don’t want to worry about running out of data in a country you don’t know, GigSky may not be the best option for you. 

Key features

GigSky offers simple data eSIM services made for travelers seeking basic connectivity:

• Provides limited data plans, with the largest option offering 10 GB for 30 days
• Free 7-day plan with 100 MB of data, ideal for testing the data eSIM
• Requires creating an account and buying plans through the GigSky app for iOS or Android
• Supports 24/7 customer assistance, though live chat is only available in their Help Center
• Payments can only be made with credit or debit cards

Plans and prices

• 100 MB (7 days): Free
• 1 GB (7 days): 4.49 USD
• 3 GB (15 days): 9.49 USD
• 5 GB (30 days): 12.99 USD
• 10 GB (30 days): 20.99 USD

While a free eSIM sounds very compelling, keep in mind that 100 MB is barely enough for you to test it out and see if it really works, considering that you’ll spend this amount of cellular data for an hour of Instagram browsing.

3. Yesim

Yesim is fairly new in the eSIM market. It offers unlimited and limited data plans, although the shorter plans are noticeably more expensive than others on this list.

Key features

Yesim combines flexibility and convenience, catering to travelers with diverse connectivity needs:

• Offers both limited and unlimited data plans for short and long-term trips
• Plans can be purchased and managed through the Yesim app, which is available for iOS and Android
• Wide range of payment options, including credit/debit cards, PayPal, Apple Pay, and more
• 24/7 customer support 
• Requires creating an account for purchase and activation, which may add an extra step for users
• Pricing can be an issue for more budget-oriented users

Plans and prices

Depending on how much data you want to spend with your Vietnam tourist eSIM, you can choose from Unlimited and Standard plans.

Standard plans

• 3 GB (7 days): $11.00 USD
• 5 GB (15 days): $16.50 USD
• 10 GB (30 days): $27.50 USD
• 20 GB (30 days): $41.80 USD

Unlimited plans:

• 1 day: $7.70 USD
• 7 days: $38.50 USD
• 15 days: $53.90 USD
• 30 days: $74.80 USD

Yesim also has a cashback program. You can buy Ycoins or earn them with every purchase. Once you buy them, though, you can only spend them on your next Yesim purchase.

4. JetPac

Jetpac stands out with its Smart Delay service, which offers free airport lounge access if your flight is delayed by more than an hour. However, there are conditions and limitations to this perk and some travelers report that it is too complicated to use and the offer is easily rendered invalid. 

Key features

Jetpac has some perks for frequent flyers, though it has some limitations. On the other hand, their offer is somewhat limited:

• Smart Delay service grants lounge access for flights delayed by over 60 minutes (conditions apply)
• Ability to bring up to five companions for lounge access if covered by your plan
• Coverage on local networks, though some users report slower 3G connections
• No obvious 24/7 customer support mentioned on their website
• JetFlex and JetPro plans are monthly subscriptions tailored to frequent travelers
• No unlimited data plans

Plans and prices

JetPac doesn’t have a digital SIM card that’s specific to Vietnam. They have a South Asia eSIM that covers Vietnam among other countries.

• 1 GB (4 days): $4 USD
• 3 GB (7 days): $10 USD
• 5 GB (15 days): $15 USD
• 5 GB (30 days): $18 USD
• 10 GB (30 days): $29 USD
• 20 GB (30 days): $39 USD

5. aloSIM

aloSIM is a Canada-based eSIM provider offering prepaid data plans for over 170 destinations. It also doesn’t provide unlimited data or call and SMS features, but it stands out for its offer of a Hushed international number for registration codes.

Key features

aloSIM offers a standard set of features that cater to travelers, although it has some limitations compared to other providers:

• Coverage in over 170 destinations, including regional plans for Europe, Scandinavia, and the Mediterranean
• Plans include a Hushed international number
• Offers shared account options for families or groups traveling together
• The app allows SIM management and top-ups
• Connectivity options include LTE, 4G, and 5G speeds, depending on the destination
• 24/7 in-app customer service, though support relies on an AI chatbot before connecting to a live agent

Plans and prices

While aloSIM offers various plans for individual countries and regions, it lacks unlimited data options and a fully transparent refund policy.

• 1 GB (7 days): $4.50 USD
• 2 GB (15 days): $7.00 USD
• 3 GB (30 days): $9.50 USD
• 5 GB (30 days): $13.00 USD
• 10 GB (30 days): $21.00 USD

aloSIM also has a loyalty program in which you can earn aloCASH with every purchase. This makes sense only if you plan on using this provider for multiple destinations.

6. SimOptions

SimOptions is a marketplace offering both its own eSIMs and SIM card plans, along with products from other providers like O2, Orange, or Three. For Vietnam, SimOptions exclusively sells their own eSIMs and doesn’t offer any of the partner eSIM options

Key features

SimOptions’ strongest point is its wide offering, which includes different providers. However, that’s also its biggest weakness, as it means that the reach of its customer support is limited, as it is not the main eSIM provider in many cases. 

• Coverage in over 200 countries with country-specific and regional plans
• Simple activation process via QR code for most eSIMs
• Compatible with most eSIM compatible smartphones (check compatibility with *#06#)
• Customer support available via live chat, email, and phone, but with limited ability to actually help
• Strict refund policy — refunds are only given for activation issues caused by SimOptions or the provider

Prices and plans

SimOption Vietnam eSIM cost starts at 4.50 USD for 7 days. Here are the detailed costs and plans.

• 1 GB (7 days): $4.50 USD
• 3 GB (30 days): $8.90 USD
• 5 GB (30 days): $13.90 USD
• 10 GB (30 days): $25.90 USD
• 20 GB (30 days): $47.90 USD
• 30 GB (30 days): $67.90 USD
• 50 GB (30 days): $107.90 USD

7. FlexiRoam

FlexiRoam is yet another popular eSIM provider in Vietnam, with quite a few plans to choose from. The provider offers unlimited and limited data plans that last 5 to 30 days. 

However, Flexiroam limits your download speed after the first 3 GB is used within a day. For reference, one long movie on Netflix will eat up that first 3 GB, and you will be left struggling to use your data plan until the speed resets.

Key features

Flexiroam is a legitimate option when choosing your Vietnam tourist data eSIM, but it has some limitations worth noting:

• Offers both limited and unlimited data plans for different travel needs
• Unlimited plans come with a daily speed cap after 3 GB of usage
• Requires activation through the FlexiRoam app, available on iOS and Android
• Provides 24/7 customer support
• Payment process via credit or debit card, though no alternative payment methods are available

Plans and prices

While Flexiroam’s pricing is fair, you should remember that unlimited plans have speed restrictions and that all eSIM activations must be done through their app. Here’s a quick rundown of all Flexiroam Vietnam eSIM plans:

Fixed plans

• 1 GB (7 days): $4 USD
• 2 GB (15 days): $7 USD
• 3 GB (30 days): $9.50 USD
• 5 GB (30 days): $13 USD
• 10 GB (30 days): $20 USD

Unlimited plans

• 5 days: $19 USD
• 7 days: $27 USD
• 10 days: $34 USD
• 15 days: $47 USD
• 20 days: $54 USD
• 30 days: $64 USD

Note: A pop-up ad appears at the bottom of the Vietnam eSIM page and grays out the entire screen, but you can dismiss it by clicking the cross. However, for less tech-savvy users, this may cause some confusion as it redirects to their Global Tourist eSIM page if not closed.

How we chose the best eSIM for Vietnam

Choosing the best Vietnam eSIM data plan depends on your travel needs, and we used three main criteria to evaluate the top options. From mobile data usage to coverage and pricing, here’s how we determined that Holafly is the top choice among the eSIMs for Vietnam:

Data plans and duration

Flexibility in mobile data and trip length is essential. Holafly excels with unlimited data and plans ranging from 1 to 90 days, ideal for navigating, staying active on social media, or video calling. Matching your plan to your trip duration ensures you don’t overspend or run out mid-trip.

Coverage and reliability

Strong coverage is a must, especially outside major cities. Holafly connects to Vietnam’s top networks, including Vinaphone, Mobifone, and Viettel, delivering the same quality as a local SIM card. With Holafly, you can count on reliable service wherever you travel.

Price comparison

While price is important, unlimited data from Holafly offers the best value. You avoid the hassle of monitoring usage, and Holafly’s pricing ensures seamless connectivity at a competitive daily cost. Choosing a Vietnam eSIM with unlimited data simplifies your trip and eliminates data roaming concerns.

How to buy and activate an eSIM card for Vietnam

There are only a few minutes and three simple steps between you and your eSIM card for Vietnam. Here’s what you need to do to make the most of eSIM technology and avoid using additional physical SIM cards.

1. Buy your eSIM: Visit Holafly’s website, select Vietnam as your destination, choose your plan, and complete your purchase.
2. Receive your eSIM: Instantly get your eSIM QR code via email.
3. Activate your eSIM: Scan the QR code, follow the on-screen prompts, and enjoy unlimited data in Vietnam.

If this isn’t enough for you and you need help dealing with the QR code or any other step of your eSIM installation, you can always contact Holafly customer support.

Final thoughts: Which is the best Vietnam eSIM for tourists?

While pricing matters, it’s crucial to choose an eSIM that won’t leave you stranded mid-trip. Running out of data in an unfamiliar country can be as frustrating as having no eSIM at all. Opting for an eSIM for Vietnam with unlimited data plans, like Holafly’s, ensures peace of mind, especially for heavy users. Balancing cost with sufficient data and reliable coverage is the key to staying connected throughout your Vietnam adventure.
