Installing a eSIMfox eSIM for Vietnam

- Buy the plan on eSIMfox'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 eSIMfox line for data: the plan starts counting at first connection.

eSIMfox in Vietnam: questions
Which network does eSIMfox use in Vietnam?
eSIMfox connects to Vinaphone. 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 eSIMfox's unlimited plan really unlimited?
No. eSIMfox applies a daily fair-use cap: 2 GB → 1 Mbps. Light use is never affected; video and tethering are.
Do I get a Vietnamese phone number with eSIMfox?
No. eSIMfox is data-only: no Vietnamese number, so no Vietnamese SMS. Calls go through WhatsApp or your home line in roaming.
Can I share eSIMfox's connection as a hotspot?
Yes
When does the eSIMfox plan start?
The plan starts at first connection in Vietnam. Install it at home, keep data roaming off on that line until you land.
