Planning a trip to Vietnam and looking for the best eSIM Vietnam?
Here’s a straightforward guide to choosing the right Vietnam eSIM for Malaysians — so you can stay connected throughout your trip without dealing with physical SIM cards or expensive roaming charges.
Vietnam is a popular destination for Malaysians, whether you’re travelling for a holiday, food trip, beach escape, business visit, or a mix of both. From navigating cities and booking rides to staying in touch on WhatsApp and social media, having reliable mobile data makes the entire trip smoother.
Instead of buying a physical SIM card at the airport or relying on international roaming, many travellers now choose travel eSIMs for their convenience. A Vietnam eSIM allows you to activate your data instantly via QR code, connect to local networks upon arrival, and avoid the hassle of swapping SIM cards.
Many Vietnam eSIM providers allow Malaysians to purchase plans in Ringgit, select flexible durations such as 3, 5, 7, or 10 days, and enjoy access to fast local networks. Some providers also offer unlimited-style plans with fair-use policies for travellers who use more data during their trip.

Using an eSIM in Vietnam
What is an eSIM and how does it work in Vietnam?
An eSIM is a digital SIM that you install directly on your phone—no physical card needed. Activation is usually done by scanning a QR code, and your plan’s validity follows local time in Vietnam. eSIMs work on most modern iPhones, Samsung Galaxy phones, Google Pixel models, and other eSIM-enabled devices.
Check if your device supports eSIM.Must-have apps for travellers in Vietnam
- Maps & Transport: Google Maps, Grab, Moovit
- Payments: GrabPay, Google Pay, Apple Pay (widely accepted in major cities)
- Ride-hailing & Taxi: Grab, Be, Mai Linh Taxi
- Travel & Tickets: Klook, Trip.com, Agoda
- Messaging: WhatsApp, Telegram, Zalo, LINE
Differences between eSIMs and traditional SIM cards
Buying a physical SIM in Vietnam usually requires visiting a shop or convenience store (e.g., 7-Eleven, Circle K) and may involve waiting or filling in registration details. With an eSIM, you can:
- Activate instantly without visiting a store
- Arrive connected the moment you land
- Keep your Malaysian number active (dual-SIM support)
- Avoid swapping or misplacing tiny SIM cards
