nextSIM eSIM Data Plans for Vietnam

nextSIM does not provide a truly unlimited data eSIM plan for Vietnam. All plans that carry the word “Unlimited” in their name actually grant a fixed amount of high‑speed data and then throttle speed to 512kbps or 2000kbps once the allowance is reached; for example, the eSIM Unlimited Standard 1 Day VietNam plan allows 1GB of high‑speed data per day before the speed drops.

If a traveler needs more data, nextSIM offers fixed‑amount plans that may be more cost‑effective. One example is the eSIM Vietnam 50GB 30Days Economy plan, which provides 50GB of high‑speed data for 30 days, and another is the eSIM Vietnam 20GB 30Days Economy plan with 20GB for 30 days. These Plans deliver the full high‑speed data without the speed reduction that applies to the “Unlimited” offers.

nextSIM does not offer an eSIM plan for Vietnam that includes a local phone number or SMS capability. Their Vietnam plans are strictly data‑only, allowing travelers to use the data allowance for internet access via 5G, 4G, or 3G depending on coverage.

Travelers who need voice or text can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, as these apps do not require a traditional phone number or SMS service.

nextSIM offers a total of 29 single‑country plans and 34 multination‑country plans that include Vietnam. The single‑country offerings provide only local data service for Vietnam, while the multination plans bundle Vietnam with other destinations.

The plans span a price range from17 up to $1,299.53 and a data cap range of 1 GB to 50 GB, with validity periods between 1 and 30 days.

Among the plans, 24 are structured as daily data cap packages, meaning the data allowance refreshes each day of the validity period, whereas 39 are fixed‑data‑cap plans that provide a one‑time data allotment that does not reset daily. Both types are available to suit different usage patterns.
