No eSIM? Take a SIM card
If your phone does not support eSIM, the same plan is available as a physical SIM card, sent to you before you fly. Either way you skip the airport SIM counter and the queue with your passport.


Vietnam has become one of the easiest long weekends out of India, with direct flights into three cities. The plan connects wherever your trip starts, and your Indian number keeps taking bank OTPs.

Buy a plan, scan the QR code, and turn on mobile data. Your eSIM is ready in about 2 minutes.

Book your Vietnam data plan online before you fly. Your QR code comes by email in seconds, so you do not need to find a SIM shop after landing.
The eSIM works as a second line on your phone. Your Indian number stays on for calls, SMS and bank OTPs, and Olysim gives you the internet data.
Pay one fixed price for the data you need in Vietnam. There is no daily international roaming charge and no extra bill after you return.
An eSIM is a digital SIM already built into your phone. You do not remove your Indian SIM or carry a spare tray pin - you simply add a new data plan and switch it on when you land.
After you pay, your eSIM QR code reaches your email within seconds. Scan it once from your phone settings and the plan is installed. You can do this at home before your flight.
If your phone does not support eSIM, the same plan is available as a physical SIM card, sent to you before you fly. Either way you skip the airport SIM counter and the queue with your passport.
Yes. If your phone doesn't take an eSIM, or you'd rather not touch its settings while travelling, the same Vietnam plan ships as a physical SIM.
Yes, as long as your Indian SIM stays in the phone's other slot for calls and texts - OTPs keep arriving normally while the Vietnam data plan does the rest.
Yes - buy it, scan the QR code over Wi-Fi at home, and it switches on by itself once you land in Vietnam, with nothing to do at a local counter.
Add more data to the same eSIM or SIM from the Olysim app whenever you need it, without hunting for a shop in Vietnam.
