nextSIM eSIM Data Plans for Vietnam

There are no truly unlimited‑data eSIM plans from nextSIM for Vietnam.
All plans labelled as “Unlimited” in the product catalogue actually offer a fixed data cap—typically 1 GB per day with a speed reduction to 512 kbps once the limit is reached, or a 2 GB cap with a 2 Mbps throttled speed.

Travelers who need more data can choose from the fixed‑data options, such as the 100 GB 30 days standard plan or the 50 GB 30 days plans that provide high‑speed data for the full allowance. These plans are often more cost‑effective for heavy data users than the limited‑cap “Unlimited” packages.

nextSIM does not offer a Vietnam eSIM with a phone number or the ability to send SMS. The provider’s Vietnam plans are data‑only, so travelers will only receive mobile data on a 4G network.

Users can still communicate while traveling by using popular VoIP applications such as WhatsApp, Telegram, or iMessage, which work over data connections and provide voice and messaging services without requiring a local phone number or SMS capability.

nextSIM provides a broad catalog of options that include Vietnam. Among its single‑country offerings there are 60 plans that cover Vietnam, while its multi‑country packages include 62 plans that also include Vietnam. The plans span a price range from about $2.11 to $1, 299.69 and offer data caps from 1 GB up to 100 GB, with validity periods ranging from 1 to 365 days. Some of the plans are fixed‑data packages, while others use a daily data‑cap model, allowing users to choose a structure that best fits their expected usage.
