Short on Time? Here Are the Best eSIMs for Vietnam in 2025

Best eSIMs for Vietnam in 2025

1. Holiday — Best Overall eSIM for Vietnam

Holiday.com is an excellent choice for staying connected in Vietnam. It comes with user-friendly apps, flexible plans, and reliable performance. Holiday offers the most affordable plans for Vietnam, starting at just $3.50 for 1GB (valid for 5 days). Plus, if you’re an ExpressVPN subscriber, you can snag coupon codes for free data through the Holiday service.

Setting up the Holiday eSIM is quick and straightforward. Just download it to your device, and it will automatically activate when you arrive in Vietnam. When I used Holiday there, I had no trouble accessing everything from Facebook to my banking apps. Plus, with 5G support and hotspot tethering, you can share your data with other devices effortlessly.

Keep in mind that Holiday offers data-only plans, so voice calls and SMS aren’t included. However, you can still use apps like WhatsApp or Skype to make calls. Holiday keeps pricing straightforward with no hidden fees. Plus, if your eSIM isn’t activated, you’re backed by a 14-day money-back guarantee.

2. Saily — A User-Friendly eSIM for Vietnam

Developed by Nord Security, Saily offers an easy-to-use eSIM service with a hassle-free setup. The app makes managing your account simple — you can track your data usage, top up your plan, and reach 24/7 customer support whenever needed.

Saily supports 5G connections and tethering, so you can share your data with other devices via a mobile hotspot. Plus, the app automatically activates your plan as soon as you arrive in Vietnam — that let me access my social media accounts without interruptions.

The pricing is affordable, starting at $3.99 for 1GB (valid for 7 days), and you can even bring the price down to $3.79 using the Mentor5 coupon. Saily offers many data-only plans (for example, 1GB, 5GB, and 10GB), but it doesn’t go beyond 20GB, which may not suit heavy data users. Similar to the Holiday eSIM, there are no voice and text options.

3. Airalo — Best for Local Vietnam eSIMs

Airalo offers excellent local coverage in Vietnam with dedicated Xin Chao plans, partnering with Mobifone and Viettel networks. You can get 1GB of data for $4.50, and the service is completely transparent — there are no hidden fees or contracts to worry about.

Installing an Airalo eSIM is simple — all it takes is a quick QR code scan. Its global coverage spans 200+ countries, making it ideal for travelers exploring Vietnam and other Southeast Asian countries like Thailand or Cambodia. Plus, it helps you access your favorite services and social media accounts like TikTok from anywhere.

The only issue is that the plans are slightly pricier than other recommended eSIMs. However, the speed and reliable connection make up for the added cost. Plus, you get travel rewards with its Airmoney loyalty program, which gives cashback on every purchase.

4. Airhub — Best eSIM for Voice Calls and SMS in Vietnam

Airhub is an excellent choice for staying connected in Vietnam, offering plans with unlimited data, voice calls, and texts. Unlike most eSIM providers that cap data at 20GB, Airhub gives you the flexibility to use as much as you need. You can also opt for a data-only plan if you prefer.

The eSIM operates on the Vietnamobile Network, providing decent coverage across Vietnam, even in more remote areas. This is great if you want to reliably access your Facebook or Instagram account without losing quality or slowing down. However, the customer service isn’t very responsive. I experienced delays in receiving the QR code required for setup, but once it arrived, the installation was quick.

5. GigSky — 100MB of Free Data Allowance

GigSky offers a free plan for travelers in Vietnam, giving new users 100MB of data for 7 days — no credit card needed. It’s a great way to try the service before upgrading to a paid plan.

According to Reddit users, GigSky works well in major cities but can be less reliable in remote areas. However, many had a smooth experience in popular spots like Halong Bay and Phu Quoc, making it easy to access social media and banking apps on the go.

Things to Know About Using eSIMs in Vietnam

Here are a few key tips to make sure everything goes smoothly when you’re in Vietnam:

• Device compatibility. Before you go, make sure your phone supports eSIMs and is unlocked for use with different carriers. If it’s not, you won’t be able to install or activate an eSIM in Vietnam.
• Coverage and network speeds. eSIMs typically provide solid 4G or 5G speeds, but coverage can vary depending on where you are. Big cities like Hanoi and Ho Chi Minh have excellent connectivity, while rural areas might be a bit spotty.
• Data usage limits. It’s easy to burn through your data when you’re navigating, booking rides, or streaming. To avoid extra charges, pick a plan that matches your usage and keep track of how much you’re using.
• Activation process. Most eSIMs automatically activate when you arrive in Vietnam, but some may need manual setup. Be sure to follow the instructions from your provider to get connected hassle-free.
• Multi-country compatibility. If Vietnam is just one stop on your Southeast Asia adventure, look for an eSIM that works in neighboring countries like Thailand or Cambodia. A multi-country plan can save you the trouble of buying a new eSIM for each destination.

Does Your Phone Support eSIM?

Before buying an eSIM for Vietnam, it’s essential to check if your phone is compatible with it. Not all devices support eSIM technology, and confirming this in advance can save you time and ensure a hassle-free connection while traveling.

Here’s a simple guide to help you verify eSIM compatibility on iPhones and Android devices:

eSIM on iPhones

Apple introduced eSIM support with the iPhone XS, XS Max, and XR models in September 2018. Since then, all subsequent iPhone models have included eSIM functionality:

• iPhone XS, XS Max, and XR
• iPhone 11, 11 Pro, and 11 Pro Max
• iPhone SE (2nd generation)
• iPhone 12, 12 mini, 12 Pro, and 12 Pro Max
• iPhone 13 series
• iPhone 14 series
• iPhone 15 series

However, the availability may depend on your region and model. Here’s how to check it:

Step 1. Head to Settings and search for eSIM. If you see the Add eSIM option, tap it.

Step 2. Follow the prompts to scan a QR code and start setup. If the process begins, your iPhone supports eSIM.

iPhone 14 models sold in the US no longer include a physical SIM slot, making eSIM the only option

eSIM on Android Devices

Many Android devices from leading brands now include eSIM support. While Android doesn’t have a universal setting for checking compatibility, here’s a general approach:

Step 1. Head to Settings and search for eSIM. If you see the Add eSIM option, tap it.

Step 2. If you’re redirected to a setup page, your phone supports eSIM.

Some carriers may require specific apps to activate an eSIM (e.g., Google Fi or My Verizon)

How to Buy a Prepaid SIM Card in Vietnam?

If your phone doesn’t support eSIM, a prepaid SIM card is another option for staying connected in Vietnam. However, eSIMs are often simpler and more hassle-free.

1. Where to buy. You can find prepaid SIM cards at airports, convenience stores, and official carrier outlets. Airports are convenient but tend to charge higher prices, so buying in the city is often cheaper.
2. Choosing a provider. Viettel, Mobifone, and Vinaphone are the main carriers in Vietnam, known for their reliable coverage and variety of plans. Compare their options to pick one that fits your budget and data needs.
3. What you’ll need. Vietnamese law requires ID verification for SIM activation. Make sure to bring your passport to register for the SIM.
4. Check data plans. Match the data plan to your trip duration and usage. Short-term visitors can choose smaller plans, while longer stays or heavy usage might require larger data packages.
5. Activate your physical SIM. Vendors typically activate the SIM for you. If they don’t, follow the instructions provided with the SIM package. Most SIM cards are ready to use within minutes.

eSIM vs Prepaid SIM in Vietnam

When choosing between an eSIM and a prepaid SIM in Vietnam, it ultimately comes down to your specific travel needs and preferences. Both options have their advantages, so understanding the key differences will help you pick the best one for your trip.

How to Stay Safe on Public Hotspots in Vietnam

Public WiFi in Vietnam can be a lifesaver for travelers, but it also presents significant risks. Hackers often target these networks to steal sensitive data, which can lead to phishing, malware attacks, or identity theft. However, with the proper precautions, you can stay safe while using public hotspots:

• Use a VPN. A virtual private network encrypts your internet connection, making it nearly impossible for hackers to intercept your data. The best VPNs for Vietnam protect your online activity and prevent hackers from intercepting your data.
• Avoid accessing sensitive accounts. Don’t log into sensitive accounts — like online banking or email — while connected to public WiFi. Save these tasks for when you’re on a private, secure network.
• Turn off automatic connections. Turn off the WiFi auto-connect feature on your device. This will prevent your phone or laptop from automatically connecting to unsecured networks, ensuring you stay on safe, verified networks.
• Verify the network name. Before connecting to any public WiFi, confirm the network name with staff or official signage. Hackers often create fake networks with similar names to trick you into connecting to them.
• Use HTTPS websites. When browsing, always choose websites with HTTPS. This ensures that your connection to the site is encrypted. If a website doesn’t have HTTPS, it’s best to avoid it, as it may not be secure.
• Use a secure browser. Secure browsers can help block malicious websites and keep your personal data safe. Popular options like Brave or DuckDuckGo are designed to enhance your online privacy.
• Keep your device updated. Ensure your device, apps, and antivirus software are always up to date. Updates often include fixes for security vulnerabilities that hackers can exploit.
