How to Set Up Your Vietnam eSIM (It’s Easier Than You Think)
Let us go through the steps in which to can set up this eSIM:
Step 1: Check Device Compatibility
Before you begin, check if your phone supports eSIM. Just for your reference, most newer models of iPhones and android devices do.
- iOS: Settings → Cellular → Add Cellular Plan
- Android: Settings → Network & Internet → SIMs
If you see an option to add a mobile plan, you’re good to go!
Step 2: Purchase the Plan
Head to the Olysim website, choose a Vietnam travel eSIM plan based on how long you’re staying and how much data you’ll need. Options range from small-data plans for casual use to unlimited options for streamers and remote workers.
Step 3: Scan the QR Code
Once you complete your purchase, you’ll receive a QR code via email. Open your camera or settings menu to scan and install your new mobile plan. You’ll be prompted to label it (e.g., “Vietnam eSIM”).
Step 4: Turn It On
Once installed, go to your settings and turn on the new line. You need to then enable “Data Roaming” for your eSIM. Now, you’ll be connected in no time.
Pro Tip: Activate the eSIM while you’re still on Wi-Fi, ideally at home or at the airport lounge before departure. That way, you're not trying to get online while juggling your bags at the arrivals terminal.

Travel Tips in Vietnam (Staying Connected & Smart)
An eSIM is just one piece of your travel toolkit. Here are a few more travel tips in Vietnam to make the most of your adventure:
Download Offline Maps
Even with great data, having Google Maps downloaded for Hanoi or Da Nang is a lifesaver if you hit a no-service zone.
Learn a Few Vietnamese Phrases
Locals appreciate the effort, and it might just get you a better deal at the market. Start with “Cảm ơn” (thank you) and “Xin chào” (hello).
Stay App-friendly
Use apps like Grab for rides, Zalo for local messaging, and Foody for restaurant reviews.
Be Cautious With Public Wi-Fi
Cafes and hotels offer free Wi-Fi, but don’t use it for sensitive tasks like banking. Your eSIM is far more secure.
Keep a Power Bank Handy
With all that map-checking, photo-taking, and posting, your battery won’t last long. Always carry a backup.
