Airport SIM & eSIM Prices

Vietnam's largest carrier by network reach, with the strongest 4G/5G coverage of the three even in rural and mountainous areas outside Hanoi. Sold at an English-staffed counter directly past customs; passport required for the mandatory SIM registration.

A state-owned carrier's tourist SIM bundling 2GB of data per day plus 100 minutes of calls, valid 30 days — a solid mid-range data allowance for a month-long trip, sold at its own arrival-hall counter alongside Viettel and Mobifone.

The third of Vietnam's big three carriers, also sold at its own Noi Bai arrival-hall counter with data-focused tourist packages — a fallback option when the Viettel or Vinaphone queue is long.

A QR-code-activated eSIM runnable on Viettel's 4G/LTE network, purchasable and installed before departure so it's active the moment the plane lands — unlike India, Vietnam has not blocked Airalo or similar eSIM services as of this research date, confirmed via multiple current 2026 eSIM-comparison guides reporting normal operation.
