Are you planning a trip to Vietnam in 2026? Instead of spending time looking for a physical SIM card after landing, a Vietnam eSIM is a convenient solution that helps you stay connected from the first moments of your journey. In this guide, Vietnam Sky Service provides essential information about Vietnam eSIM, how to choose the right plan, and step-by-step instructions on how to install and activate your eSIM before arriving in Vietnam.
What Is an eSIM?
eSIM (Embedded SIM) is a digital SIM built directly into your device, so you do not need to insert or replace a physical SIM card. The installation process is usually completed through a QR code, an application, or activation details provided by the mobile network operator or eSIM provider.
eSIM only works on devices that support this technology, such as iPhone XS and later models, selected Samsung Galaxy models including S20, S21, S22, S23, S24, S25, and other compatible smartphones. Support may vary depending on the device version, distribution region, and mobile network.
In Vietnam, eSIM services are currently available from major mobile network operators, including Viettel, VinaPhone, and MobiFone. Therefore, travelers can use a Vietnam eSIM for mobile data or phone services, as long as their device and selected plan meet the provider’s requirements.
Benefits of Using a Vietnam eSIM
Compared with a physical SIM card, eSIM offers greater convenience, especially for travelers who move frequently or need to manage multiple connections on the same device.
-
No need to remove a physical SIM card: Since eSIM is built directly into your device, you do not need to remove or replace SIM cards whenever you change networks or plans. This also reduces the risk of losing or damaging your SIM card during your trip.
-
Easier switching between plans or mobile networks: Many devices allow users to store multiple eSIM profiles and switch between them directly in the settings. You do not need to physically change SIM cards when using a different plan.
-
Use multiple numbers on the same device: Depending on your device model, you can keep your main SIM card for calls or OTP messages while using a Vietnam eSIM for mobile data. This is especially useful for international travelers who want to keep their existing phone number while staying connected in Vietnam.
-
Better security in certain situations: Since eSIM is integrated into your device, it cannot be removed like a physical SIM card if your phone is lost or stolen. However, you should still use screen locks, biometric authentication, and other device security features to protect your personal information.
Which Should You Choose: Viettel, VinaPhone, or MobiFone?
All three major networks in Vietnam — Viettel, VinaPhone, and MobiFone — can meet basic Internet needs for travelers. If you are mainly staying in major cities and popular tourist destinations, the difference between these networks is usually not significant.
However, if your itinerary includes mountainous areas, rural locations, or multiple provinces, you should consider choosing a network with coverage that matches your travel route.

For travelers visiting Ha Giang, Sapa, mountainous provinces, or remote destinations, Viettel is often considered a safer option in terms of coverage. However, you should still check the latest coverage maps and available plans before purchasing, as actual connection quality may vary depending on each location.

Check when the validity period starts: Some eSIM plans start counting the validity period immediately after installation, while others begin when the eSIM connects to a network in Vietnam. Confirm this information before purchasing to avoid losing unused days.
-
Confirm the mobile network used in Vietnam: If you plan to visit mountainous areas, rural regions, or multiple provinces, check whether the eSIM uses Viettel, VinaPhone, or MobiFone to select the most suitable option for your itinerary.
