Landing in Vietnam without mobile data is an annoying way to start your trip. You end up relying on airport Wi-Fi, searching for a SIM counter, or paying high roaming charges just to get online. With a Vietnam eSIM, you can buy your plan before departure, receive it instantly by email, and install it in minutes on a compatible phone.
Travelsim Asia keeps things simple: no app, no account, and no plastic SIM card to swap. Once installed, you can manage your eSIM from your portal, where you can check your remaining data, see your expiry date, and buy a top-up if needed.
If you’re ready to choose a plan now:
The best Vietnam eSIM plan depends on how you travel. Some people only need data for maps and messaging, while others want enough for social media, hotspot use, or longer stays.
1GB to 3GB plans — maps, messaging, and light browsing
A smaller plan is a good fit if you mainly use Google Maps, WhatsApp, email, translation apps, and a bit of casual browsing while you’re out exploring.
5GB to 10GB plans — the best fit for most travellers
For most tourists, this is the sweet spot. It gives you enough data for daily navigation, booking apps, social media, photo sharing, and regular web use without worrying too much about running out.
20GB+ plans — heavy use, hotspot, work, and video
Choose a larger plan if you work remotely, tether to a laptop, spend a lot of time on Instagram or TikTok, or stream video while traveling around Vietnam.
If you underestimate your usage, you can always top up later from your portal instead of starting over with a new eSIM.
The easiest setup is to install your eSIM before you fly, while you still have a stable Wi-Fi connection. That way, everything is ready before you land and you can get connected faster on arrival.
A simple setup flow looks like this:
One important note: travel eSIMs often require Data Roaming to be turned on for the eSIM line. That does not mean you are roaming on your home provider. It simply allows your travel eSIM to connect to its partner network in Vietnam.

One of the most useful parts of Travelsim Asia is the portal. Instead of guessing how much data you have left, you can check it anytime during your trip.

That means you stay in control while you travel. If your trip changes or you use more data than expected, you can simply top up instead of buying a completely new plan.
A Vietnam eSIM is ideal for common travel routes across the country, including major destinations like Ho Chi Minh City, Hanoi, Da Nang, Hoi An, Nha Trang, Phu Quoc, and Ha Long Bay. Once installed, it helps you stay connected for maps, ride apps, bookings, messaging, and everyday travel use while moving around.
Coverage and speed can vary by location and network, but for most tourists, a Vietnam eSIM is the easiest way to get online throughout the trip without dealing with local SIM shop hassle.
If Vietnam is only one stop on your trip, a regional plan may be more convenient than buying a separate eSIM for each destination.
