We recommend activating your EastESIM for Vietnam either just before you depart or upon arrival. The most convenient approach is to scan the QR code and complete the installation while you have a stable Wi-Fi connection at home or at your departure airport. This ensures your EastESIM is active and ready to connect the moment you land at Tan Son Nhat International Airport (SGN) in Ho Chi Minh City or Noi Bai International Airport (HAN) in Hanoi. You'll have immediate access to maps, translation apps, and communication without searching for public Wi-Fi.
