ESIMFUN lists several “Unlimited” eSIM options for Vietnam, but each of those plans actually contains a fixed 100GB data allowance with no speed reduction for the stated validity. This means that after the 100GB is used, the plan cannot provide additional high‑speed data. Therefore ESIMFUN does not offer a truly unlimited data eSIM for Vietnam.
Instead, ESIMFUN provides fixed‑data plans that may suit travelers needing a large amount of data. For example, a 30‑day plan gives 100GB for $45.79 USD, while a 15‑day plan offers 100GB for $34.92 USD. These fixed‑data plans can be a more cost‑effective choice unless a user expects exceptionally heavy data consumption.
ESIMFUN does not offer any eSIM plans for Vietnam that include a local phone number or SMS capability. All available plans from ESIMFUN for Vietnam are data‑only and provide internet access without voice or text services.
Because the plans are data‑only, travelers can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging, but they will not receive a traditional mobile phone number or the ability to send or receive SMS texts.
ESIMFUN lists 30 multi‑country eSIM data plans that include coverage in Vietnam, with no single‑country options for the country. The plans span a price range from about $8.18 to $208.52 and offer data caps from 1 GB to 100 GB. Roughly half of the options (15 plans) provide a daily data allowance that is reset each day, while the remaining 15 plans use a fixed data amount that is available for the entire validity period.
