WiFi & Connectivity
Stay connected at Noi Bai International Airport — free WiFi, eSIM options and local data for Vietnam.
Airport WiFi at HAN
No registration required — connect and browse immediately.
Vietnamese eSIMs and physical SIMs (Viettel, Vinaphone, Mobifone) are sold at kiosks right in the arrivals hall and activate almost immediately — buying on arrival is generally cheaper and more dependable than counting on terminal wifi for anything data-heavy.
Connect and tap through the splash page — no OTP or passport number needed, which isn't universal at airports in the region, so it's a genuine convenience for checking messages before immigration. Coverage is solid in the newly expanded T2 international terminal (reopened December 2025), though the new space is large enough that signal can feel patchier at the far ends of the concourse.
