GM Vietnam, Vietnam Blockchain Week
Vietnam has no eSIM plan of its own in our catalog yet, so this page sells the regional one that covers it, and tells you exactly what else it covers.
For the people who fly in to work. The flight, the venue, the taxi, the deck, the call and the dinner, on one line.

Evidence
Two to three devices per attendee, and log-ins alone spike past a thousand at once.
rottenwifi.comExhibitors reported the Wi-Fi dropping every time footfall peaked. Reported as the pattern at nearly every large venue.
deadzones.comEvil Twin has its own MITRE ATT&CK entry. DEF CON's Wall of Sheep lists what gets picked off conference Wi-Fi.
MITRE ATT&CK T1557.004If it does not work you get a replacement, free, for the whole trip and not only on day one.
Scan the QR at home. Nothing starts counting until you land.

A person, not a bot loop, for the whole trip.
Why
Vietnamese SIM registration wants a passport and a shop visit; an eSIM wants neither
Grab is the taxi, the food and the courier, and it is an app
A conference trip to Hanoi is usually a trip to Singapore or Bangkok too, and this plan covers both
Hotel Wi-Fi in the Old Quarter is fine for email and not for a call.
Local knowledge
One plan, 18 countries: Vietnam, Singapore, Thailand, Japan, Korea, Taiwan, Hong Kong, Malaysia, the Philippines, Indonesia, India, Australia, New Zealand and more. Useful when the trip is a tour, not a city.
Grab for cars and bikes. Cash is still normal for street food, and the notes have a lot of zeros.
Cards work in hotels and malls. VietQR is everywhere else and is domestic only.
GM Vietnam ran in Hanoi in 2025. Its own site still points at the 2025 ticket page, so treat any 2026 or 2027 date you see on a listing site as somebody's guess.
Check
Dial *#06#
If an EID appears, your phone takes an eSIM.
No EID? Don't buy this. Buy a physical SIM at the airport instead.
Questions
Not at purchase. Buy today; your days begin the first time the eSIM connects in the country.
About two minutes. We email a QR code; scan it before you fly.
The regional plans keep working at 128 kbps once the high-speed data is gone. That is a map and a message, not a call. It is slower than the country plans, and we would rather say so here than have you find out in a taxi.
One-for-one replacement, and any unused plan is refunded.
It depends on the plan, and checkout shows it before you pay.
Install it tonight over home Wi-Fi. It switches itself on the moment you land at Noi Bai.
