Pros: Lowest price per GB, fast activation, Vietnam coverage on Viettel Mobile, Vinaphone and MobiFone. Cons: Newer brand, smaller community than Airalo.
HelloRoam runs Vietnam traffic on Viettel Mobile, Vinaphone and MobiFone
The best eSIM for Vietnam is HelloRoam. Signal falls into the valleys on the Ha Giang loop while the coast stays on 5G, which is why HelloRoam ranks first here: it roams on Viettel Mobile, Vinaphone and MobiFone matches it across the major cities. Most tourist-facing plans default to Viettel Mobile, and the 50 GB plan adds Vinaphone as a fallback.
Coverage analysis
Viettel Mobile, Vinaphone and MobiFone delivers 5G in Hanoi, Ho Chi Minh City, and Da Nang, covering the primary tourist corridor reliably. Vinaphone matches Viettel in major cities and adds depth in central coastal towns like Hue and Hoi An. The Sapa highlands and Ha Giang loop see 4G only, with signal dropping in deep valleys above 1,500 meters.
Activation
Install your e-sim before boarding. At Tan Son Nhat (SGN) in Ho Chi Minh City or Noi Bai (HAN) in Hanoi, Viettel Mobile, Vinaphone and MobiFone attaches on landing with no counter visit. Turn data roaming on in Settings once you are down.
Vietnam sits among the cheaper eSIM destinations at $1.37/GB on the 20 GB plan, so a 2-week trip rarely needs a top-up.
Data usage tips
Grab dominates ridesharing in Vietnam and uses under 10 MB per trip. Zalo, the local messaging app, costs roughly 5 MB per hour of chat. Budget 300-400 MB per day for standard navigation and messaging.
Add 200-300 MB daily if you stream on VPN, which many travelers use for geo-blocked content.
