How to Activate Vietnam eSIM: Step-by-Step Process

4. Connect to WiFi: Before activation, make sure your phone is connected to WiFi (required to download the eSIM profile).
5. Scan the QR Code: On your phone, go to Settings > Mobile Data/Cellular > Add eSIM or Add Mobile Plan. Use your camera to scan the QR code from your email or a printout.
6. Follow On-Screen Prompts: The device will guide you through adding and activating the eSIM profile.
7. Restart Your Device: This step is often needed for the eSIM to connect to the Vietnam mobile network.
8. Turn on Mobile Data & Roaming: In your eSIM settings, make sure mobile data is enabled, and (for many networks) set Data Roaming to ON.
9. Test Your Connection: Open a browser or app to check if you’re online—done!
