nextSIM eSIM Data Plans for Vietnam

No, nextSIM does not provide a truly unlimited data eSIM for Vietnam. All plans that carry “Unlimited” in the name actually offer a fixed amount of high‑speed data—typically 1 GB per day or a single 1 GB allowance. Once this limit is reached the speed is reduced, for example to 512kbps or 2000kbps, which limits the data further. A cost‑effective alternative for travelers who need more data is nextSIM’s fixed‑data plans, such as the 50 GB plan that lasts 30 days or the 100 GB plan that also lasts 30 days. These plans deliver the stated amount of data without any speed throttling once the allowance is consumed.

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 offers a total of 122 data plans for Vietnam, split into 60 single‑country plans and 62 multi‑country plans. The available plans range in price from about $2.11 to $1, 298.25, while data caps vary between 1 GB and 100 GB and validity periods span from 1 to 365 days. Among these options, the provider offers both daily‑data‑cap plans—where the data allowance is reset each day, and fixed‑data‑cap plans—where the data allowance remains constant for the entire validity period.
