nextSIM eSIM Data Plans for Vietnam

nextSIM does not provide a truly unlimited high‑speed data eSIM for Vietnam. The plans marketed as “Unlimited” each contain a fixed data allowance of 1GB per day, after which the speed is reduced to 512 kbps (or 2000 kbps for the Plus variants). If a traveler needs more data, nextSIM offers fixed‑amount plans such as the 100GB 30‑day plan for $74.26 USD or the 50GB 30‑day plan for $42.20 USD. These fixed data plans give a larger total bandwidth without the speed cut‑off that applies to the “Unlimited” products.

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 range of data plans for travelers in Vietnam, comprising both single‑country and multi‑country options. The provider offers 41 single‑country data plans that are valid only while you are in Vietnam, and 62 multi‑country plans that include Vietnam as part of a broader coverage area.

The overall price range for Vietnam‑specific plans spans from about $2.11 to $1, 279.81, with data caps available from 1 GB up to 100 GB. Among these, 38 plans feature a daily data cap that resets each day, while 65 plans come with a fixed data amount that does not change during the validity period. This dual structure allows users to choose between a daily‑refreshing data allocation or a traditional flat‑rate bundle, depending on their usage preferences and trip length.
