This data-only eSIM gives you 4G/LTE and 5G (where available) data across Vietnam. No registration is needed: just scan the QR code or use one-tap installation, so there is no need to swap physical SIM cards. You get up to 2GB of high-speed data every day and stay connected at reduced speed after that, and hotspot (tethering) is supported. Choose a plan from 1 to 20 days to match your trip.

Stay connected anywhere in Vietnam
with an unlimited data eSIM
This data-only eSIM works in all cities in Vietnam. Use up to 2GB of high-speed data per day, then keep browsing at reduced speed. It connects on 5G where available and 4G/LTE elsewhere, and hotspot (tethering) is supported. Choose 1, 3, 5, 7, 10, 12, 15 or 20 days to fit your trip.
Install with a QR code, no registration
After purchase, you will receive your eSIM QR code in a separate email or as a PDF attached to your confirmation email. Scan the QR code from your phone's cellular (mobile data) settings page, not the camera app, or use the one-tap installation feature. Make sure you are connected to a stable internet connection when installing; we recommend installing on the day of departure.
Turn on data roaming
when you arrive in Vietnam
When you arrive in Vietnam, turn on the eSIM and switch on "Data Roaming" to get connected. The validity period starts when the eSIM is scanned or installed. High-speed data resets to 2GB on the next calendar day, and you can still use chat apps like WhatsApp and iMessage at reduced speed.
※ This is a data-only plan. A local number, local calls and SMS are not available.
※ The eSIM must be scanned and used within 30 days of purchase and can only be scanned once.
