eSIMzio eSIM Data Plans for Vietnam

eSIMzio does not provide a plan with an unlimited data allowance for Vietnam. The “Vietnam Unlimited” names refer to a fixed bundle of 3GB of high‑speed data per day; once that daily quota is reached the speed drops to 1000 kbps. Travelers who need more continuous data can opt for one of eSIMzio’s larger fixed‑data plans, such as the 50 GB 90‑day plan or the 100 GB 180‑day plan, which offer greater data limits over a set validity period.

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 provides 12 single‑country plans and 41 multi‑country plans for Vietnam. The plans cover a price range from about $2.03 to $228.06 and data caps that span from 200 MB up to 100 GB. Among the offerings there are 12 daily data‑cap plans that refresh each day and 41 fixed data‑cap plans that deliver a set amount of data for the entire validity period. The plans are valid for 3 to 365 days, with some of the higher‑priced options including features such as tethering and a reduced speed of 1000 kbit/s.
