If you are traveling to Vietnam with an Android phone, using an eSIM is one of the easiest ways to get mobile internet without buying a physical SIM card after arrival.
Instead of waiting at airport kiosks, searching for mobile shops or removing your regular SIM card, you can install a Vietnam eSIM before departure and connect to mobile data after arriving in the country.
This is especially useful for travelers who need internet immediately for Google Maps, Grab rides, hotel communication, WhatsApp, airport transfers, translation apps and travel bookings.
Quick answer: Many modern Android phones support eSIM, including recent Samsung Galaxy, Google Pixel, Motorola, Xiaomi and other flagship devices. To use a Vietnam eSIM on Android, install the eSIM while connected to WiFi, select it for mobile data, enable Data Roaming on the eSIM profile and use data.esim as the APN if manual setup is required.
