eSIM in Vietnam
Asia
Vietnam has growing eSIM availability and reasonable urban Wi-Fi — a travel eSIM is a good safety net for long trips and rural areas.
All three major carriers support tourist eSIM with passport at airport kiosks. Wi-Fi is reliable in major cities and tourist hubs but weaker in mountainous and rural areas.
Local carriers
| Carrier | Prepaid | Tourist friendly | eSIM | Notes |
|---|---|---|---|---|
| Viettel | Yes | Yes | Yes | Largest carrier; tourist eSIM available at HCMC and Hanoi airports with passport. |
| Vinaphone | Yes | Yes | Yes | Vinaphone Tourist eSIM with broad national coverage. |
| Mobifone | Yes | No | Yes | eSIM supported but less tourist-oriented than Viettel/Vinaphone. |

Frequently asked questions
Can I use eSIM in Vietnam?
Yes — eSIM works in Vietnam via both local carriers (where available) and international travel eSIM providers. Pick a travel eSIM for short trips, or a local prepaid plan if you're staying longer.
Which travel eSIM is best for Vietnam?
It depends on trip length and data needs. Airalo has the widest catalogue, Holafly offers unlimited-data plans, Ubigi has strong corporate heritage, and Nomad emphasises transparent pricing. Compare each provider's Vietnam plan before buying.
Do I need a local SIM in Vietnam?
No — a travel eSIM is sufficient for most visitors and avoids the hassle of finding a physical SIM. Local SIMs make sense only for long stays or heavy data usage.
Is public Wi-Fi reliable in Vietnam?
Wi-Fi is reasonable in cities but spotty outside urban areas. A travel eSIM is recommended for navigation on the go.
Will my phone work with eSIM in Vietnam?
Any unlocked phone with eSIM hardware works in Vietnam. Check our compatibility pages for your specific model. Carrier-locked phones may not accept third-party eSIMs even in their home country.
