For Vietnam, the major travel eSIMs all ride the same handful of national networks — YonoSIM rides Viettel and Vinaphone 4G/5G— so value comes down to price per GB. Airalo suits light users on small tiers, Holafly bundles unlimited at a premium, and a single-country Vietnam plan often wins for a normal week — starting near a few dollars.
All Vietnam eSIMs share the same networks
Vietnam has fast, affordable mobile data in the cities and along the coast, with 5G expanding in major hubs, tracked on Ookla's Speedtest Global Index. Vietnam has three national carriers — Viettel, Vinaphone, and Mobifone. YonoSIM routes across Viettel and Vinaphone, which cover Hanoi, Ho Chi Minh City, Da Nang, and beyond — Viettel has the broadest rural reach. Because the underlying network is shared, the brand you pick mostly changes the price and how data is packaged, not the speed you get.

Which to pick for your trip
Short trip, light use:a 3–5 GB single-country plan at US$5–9 beats Airalo's equivalent tier on price per GB. Heavy streaming:compare an unlimited plan against Holafly's unlimited — the flat rate is worth it only if you'll use several GB daily. Also visiting Thailand or Cambodia after Vietnam? A regional Asia eSIM can cover the whole route on one profile; for Vietnam-only detail see our Vietnam eSIM buying guide.
FAQ
QWhich is the best-value eSIM for Vietnam — Airalo, Holafly, or a single-country plan?
AIt depends on use. Airalo suits light users who want small gigabyte tiers; Holafly suits heavy users who want unlimited and will pay a premium; a single-country Vietnam plan from a provider like YonoSIM often wins on price per GB for a normal 1–2 week trip, starting near US$5. YonoSIM rides Viettel and Vinaphone.
QDo all Vietnam eSIMs use the same network?
AEffectively yes. YonoSIM routes across Viettel and Vinaphone — the two carriers with the widest coverage across Hanoi, Ho Chi Minh City, Da Nang, and the coast. Viettel has the broadest rural reach. Real-world speed is similar; the difference between brands is price and plan structure.
QHow much data do I need for a week in Vietnam?
A3–5 GB covers a standard week of maps, Grab rides, translation, café and street-food reviews, and messaging. Choose 10 GB or unlimited if you'll stream, video-call, or hotspot a laptop. Prices run about US$2–15.
QIs unlimited data worth it for Vietnam?
AOnly for heavy users. Unlimited plans (US$18–28/week) make sense if you'll stream daily or tether devices. Most travelers spend less on 5–10 GB, since Vietnam has widespread Wi-Fi in hotels, cafés, and restaurants.
Bottom line
Since every Vietnam eSIM shares the same national networks — YonoSIM rides Viettel and Vinaphone — buy on price per GB, not brand. For most trips a single-country Vietnam eSIM from a few dollars beats Airalo and Holafly; reserve unlimited for genuinely heavy use.
