eSIMzio eSIM Data Plans for Vietnam

eSIMzio does not provide a truly unlimited data eSIM for Vietnam.
The plans that carry “Unlimited” in their names, such as Vietnam Unlimited — 3 days or Vietnam Unlimited — 7 days, actually give a fixed allowance of 3 GB per day at full speed; after that the speed drops to 1 Mbps. These are fixed data plans rather than unlimited high‑speed bundles.

If a traveler needs a larger high‑speed data allowance, eSIMzio offers fixed data plans such as Asia 100 GB — 180 days or Asia 50 GB — 30 days. These options give a larger total data capacity but still have a hard cap, unlike a true unlimited plan.

eSIMzio does not provide a Vietnam eSIM that includes a local phone number or SMS service. Travelers can only obtain data‑only eSIMs from this provider. If a caller or messenger is needed, popular VoIP apps such as WhatsApp, Telegram, or iMessage can usually be used over the data connection, though some destinations may block or limit these services, so it is advisable to confirm that the apps you rely on will work in Vietnam before purchasing.

eSIMzio offers 12 single‑country plans and 42 multi‑country plans for Vietnam. The plans span a price range from about $2.02 to $227.19 and a data cap range from 200 MB up to 100 GB. In addition to the standard fixed‑data‑amount plans, eSIMzio also provides daily data‑cap plans—13 of these give a set amount of data each day that accumulates over the validity period, while 41 plans offer a fixed total data allowance for the entire validity period.
