ESIMFUN eSIM Data Plans for Vietnam

ESIMFUN does not provide a truly unlimited data eSIM for Vietnam.
All plans listed under the “unlimited” label have a fixed high‑speed data allowance of 100GB and no speed reduction while that quota is in use, but once the 100GB limit is reached the speed would be throttled (the exact reduced speed is not specified in the data).

Instead, ESIMFUN offers fixed data plans that might be more economical for most travelers. For instance, a 100GB plan can be purchased for 5 days for about $15.48 USD, while a 100GB plan for 30 days costs around $45.87 USD. These fixed‑data options are available for Vietnam and can be a cost‑effective choice unless you need continuous unlimited data usage.

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 a total of 62 distinct data plans for travelers to Vietnam, consisting of 11 single‑country options and 51 multi‑country bundles. Prices span from $8.20 to $208.91, while data caps vary between 1 GB and 100 GB. Plan validity ranges from 3 to 30 days. Some products employ a daily data‑cap model—where a maximum amount of data is available each day—whereas others use a fixed data‑cap, meaning the entire data allotment is usable over the whole validity period.
