eSIMzio eSIM Data Plans for Vietnam

No, eSIMzio does not provide a true unlimited data eSIM for Vietnam. All Vietnam‑specific plans are limited to 3GB per day of high‑speed data, after which the speed is throttled to 1 Mbps. Travelers who need more data can choose fixed‑data plans such as the 100GB plan that lasts 180 days or the 50GB plan that is valid for 7 days, which offer large amounts of data but within a set validity period. These fixed‑data options are generally more cost effective for regular usage than relying on a short‑term high‑speed 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 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.
