Vietnam eSIM for Indian travellers - why choose Olysim
Pick the size that fits the trip
A four-day work trip and three weeks with family need very different plans, so you choose the data and the days for Vietnam. Around 3GB covers a week of maps, messaging and a daily scroll; 10GB carries a fortnight with video calls home.
Set it up in India, land connected
Your QR code arrives by email seconds after payment. Scan it at home on wi-fi, and the Vietnam line comes alive on its own once you land and switch it on.
We answer on WhatsApp, any hour
Stuck on the install, or the line will not attach after landing? Message us and a person replies, whatever the hour is where you are.
What is an eSIM, and can I get a physical SIM card instead?
A SIM built into the phone
Phones from the iPhone XS onward, and most Android flagships since 2019, carry an eSIM slot alongside the usual tray. Adding a plan writes it to that slot, and the SIM you use every day stays where it is.
The QR code is the plan
Scanning the code from your email writes the plan onto that handset. It installs once and stays there, so scan it on the phone you are actually travelling with.
No eSIM? Take a SIM card
Older handsets and a few India-bought models have no eSIM slot at all. The same plan ships to your address as a physical SIM before you fly, and works the same way once you land.

Yes. The QR code reaches you by email, you install it on home wi-fi any time after buying, and the line stays off until you switch it on after landing.
Both. If your handset has no eSIM support, the same Vietnam plan comes as a physical SIM instead, so an older phone is still covered.

About 3GB covers a week of maps, Grab rides and WhatsApp calls. Pick 5GB or 10GB if you share a lot of photos and videos, or unlimited for a longer trip.
Yes. It runs on Vietnam's three national networks, which cover the cities, Ha Long Bay cruises, Phu Quoc and the main Sapa routes. On remote mountain treks the signal can drop, the same as with a local SIM.
Yes. The plan gives you mobile data, so Grab, Google Maps, WhatsApp and Zalo all run on it.
