ESIMFUN eSIM Data Plans for Vietnam

ESIMFUN does not provide a truly unlimited data eSIM for Vietnam. All of its top‐tier plans list a capped amount of high‑speed data, even those titled “Unlimited.” For example, the 5‑day, 7‑day, 10‑day, 15‑day, and 30‑day options offer 100GB of data with no speed reduction, while the 10‑day and 15‑day options that note “2GB per day” provide a daily allowance that, once exhausted, reduces the speed rather than disconnecting the connection.

For travelers who need a large data allowance, the 100GB plans (valid for 5–30 days) are a cost‑effective choice. If a user requires even more data, a fixed data plan can be selected, but the speeds will be throttled after the allotted amount is used.

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 offers 13 single‑country data plans and 53 multi‑country data plans for Vietnam. The plans are split into daily data cap options (26 plans) and fixed data cap options (40 plans); daily plans reset each day, while fixed plans provide a set amount of data for the entire validity period. Prices range from about $8.26 to $210.48, and data caps span from 1 GB up to 100 GB.
