ESIMFUN eSIM Data Plans for Vietnam

ESIMFUN does not offer a truly unlimited high‑speed data plan for Vietnam. All of its eSIM plans are fixed‑data offers that allow a maximum of 100GB (or 2GB on some daily‑cap variants) for a set validity period; after the cap is reached no additional data is available and the speed may be throttled. A representative example is the 30‑day plan that provides 100GB of high‑speed data for $43.77 USD. Travelers who need a larger data allowance can choose a suitable fixed‑data plan, which is often more cost‑effective unless they are extremely heavy data users.

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, covering a price range of roughly $8 to $206 and a data cap that stretches from 1 GB to 100 GB. The plans come in both daily‑data‑cap versions, which limit usage on a day‑by‑day basis, and fixed‑data‑cap versions, which provide a set amount of data for the entire validity period. Validity dates vary from 3 to 30 days across the available options.
