Pros: Lowest price per GB, fast activation, Vietnam coverage on Vinaphone, Viettel Mobile. Cons: Newer brand, smaller community than Airalo.
Two carriers serve eSIM visitors in Vietnam: Vinaphone and Viettel Mobile, both on 5G. Viettel Mobile holds the largest subscriber base nationally. Vinaphone reaches 63 provinces.
Most tourist-facing plans default to Viettel Mobile, with the 50 GB multi-network plan adding Vinaphone as a fallback.
Coverage analysis
Viettel Mobile 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 registers automatically within 2 minutes of landing. Vietnam ranks among the cheapest eSIM destinations globally at $1.37/GB.
Turn on data roaming in Settings once you land.
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.
