We recommend installing your EastESIM profile and activating it just before you depart for Vietnam, or as soon as you land at Tan Son Nhat International Airport (SGN) in Ho Chi Minh City or Noi Bai International Airport (HAN) in Hanoi. Activating it while you still have a Wi-Fi connection ensures a smooth setup. This way, you'll have immediate data to navigate, order a ride-share, or contact your accommodation the moment you step off the plane, avoiding any scramble for airport Wi-Fi.
