eSIM for Vietnam — 20-day plans 🇻🇳
This 20-day eSIM for Vietnam covers tourism, business, and transit trips up to three weeks.

FAQ
What kind of trip is this eSIM best for?
It suits tourism and short business trips — think two-week holiday or a 10–15 day work assignment. Transit travellers can also use it for connection between flights.
When does the 20-day countdown start?
The clock starts the first time the eSIM connects to a live network after QR scan — not when you buy or activate the profile. For example, scan at home but connect in Vietnam only on day 3, then validity ends 20 days after that first connection.
What happens if my trip runs longer than 20 days?
The eSIM stops working after exactly 20 days. Before it expires, top up with an extension or buy a new eSIM — activate the new one when the old expires. No need to remove the old profile; just scan the new QR and switch.
Can I use this eSIM for long-term business trips?
For trips over 20 days, consider a 30-day plan instead. Business travellers on frequent short stays (10–18 days) find this 20-day option practical — just avoid activating too early.
Is eSIM activation instant after purchase?
You get the QR code by email within minutes after payment. Scan it anytime — activation starts only on first network connection, so you can wait days before scanning without losing validity.
