Vietnam eSIM: questions travelers ask
02Which networks does the Vietnam eSIM use?
The plans connect to MobiFone, Viettel Mobile, Vinaphone, with 4G/LTE nationwide; 5G in Ho Chi Minh City, Hanoi, and Da Nang. Coverage spans Ho Chi Minh City, Hanoi, Da Nang, Hoi An, Ha Long Bay, Phu Quoc, Nha Trang, and Sapa. Each plan page lists its networks and whether they offer 3G, 4G or 5G.
03Anything special about using an eSIM in Vietnam?
Coverage is excellent even in mountainous Sapa and Ha Giang regions thanks to Viettel's infrastructure investment. Overnight trains and Ha Long Bay junk cruises usually maintain signal near coastal/track areas.
04When does my Vietnam plan start?
At the first connection to a network in Vietnam, not when you buy or install it. Install at home over Wi‑Fi; the days start counting when you land.
05How do I install the eSIM?
The QR code arrives by email within minutes of payment. iPhone: Settings → Cellular → Add eSIM and scan it. Android: Settings → Network & Internet → SIMs → Add eSIM. It takes about two minutes; the help center has the step-by-step version.
06Do I keep my phone number and WhatsApp?
Yes. The eSIM carries data only and works next to your own SIM, so your number, WhatsApp, iMessage and banking apps keep working. Switch data roaming off on your home SIM so it never bills you abroad.
07What happens when the data runs out?
Add more data from My eSIMs in a minute, or switch on auto top-up after checkout and the same plan is added by itself at 90% used. Daily plans get cheaper per day the more days you buy at once.
08Can I get a refund?
Yes, in full, as long as the eSIM was never activated. A technical problem that stops activation is refunded too; write to support with your order number.
