- Check that your phone is eSIM-compatible and carrier-unlocked (Settings → About → "Digital SIM" or "EID" on Android, "Add eSIM" on iPhone).
- Buy the plan on UPeSIM's site or app and install it at home on Wi-Fi: scan the QR code or let the app add it.
- Label the line "Vietnam", keep your home SIM for calls and SMS, and turn on data roaming for the eSIM line only.
- Leave mobile data on your home line off before take-off. On landing, select the UPeSIM line for data: the plan starts counting at first connection.
- No signal after a few minutes? Toggle airplane mode, then pick the network manually in the cellular settings.

UPeSIM in Vietnam: questions
Which network does UPeSIM use in Vietnam?
UPeSIM connects to MobiFone. That choice matters more than the brand. Viettel has the widest coverage, especially in the northern mountains, the central highlands and the islands; Vinaphone and MobiFone are excellent in cities and on the coast; Vietnamobile is weak outside the big cities.
Is UPeSIM's unlimited plan really unlimited?
UPeSIM does not sell an unlimited plan for Vietnam: all its plans have a fixed data allowance.
Do I get a Vietnamese phone number with UPeSIM?
No. UPeSIM is data-only: no Vietnamese number, so no Vietnamese SMS. Calls go through WhatsApp or your home line in roaming.
Can I share UPeSIM's connection as a hotspot?
Yes
When does the UPeSIM plan start?
The plan starts at first connection in Vietnam. Install it at home, keep data roaming off on that line until you land.
