My Hanoi Trip Transformed by a Simple QR Code

On my first trip, buying a SIM was a long, confusing ordeal. Last month, everything changed. At Noi Bai Airport, I got a Viettel eSIM in minutes—just my passport and a QR code. I scanned it and was online before getting my luggage. Instantly, I booked a Grab, translated conversations, and shared photos. This seamless start set the tone. I was no longer a disconnected tourist but an informed explorer, making spontaneous decisions and always feeling secure. That simple code didn't just give me data; it gave me freedom.

Each QR code acts as a unique activation key that can be scanned only once, linking the eSIM profile permanently to the device used during the first installation.

5G Viettel on Android phones: Supported devices, setup, and fixes

  Viettel 5G on Android phones offers significantly faster speeds, lower latency, and a more stable network experience across Vietnam. However, performance depends on device compatibility, correct settings, and proper troubleshooting. Most flagship Android phones such as Samsung Galaxy S and Z series, Google Pixel, Xiaomi 13/14, OPPO Find X, and OnePlus 11/12 support Viettel 5G.

These issues can be resolved through steps like updating firmware, upgrading the SIM card to a 5G-ready version, resetting network settings, movin...
