nextSIM eSIM Data Plans for Vietnam

nextSIM does not provide a true unlimited‑data eSIM plan for Vietnam. All plans that carry the word “Unlimited” in their name contain a daily data cap of 1GB or 2GB; after that amount, the speed is throttled to 512kbps or 2000kbps. For travelers who need unrestricted high‑speed data, nextSIM offers fixed‑data plans instead. For example, a 50GB data plan for 30 days costs $43.80, and a 100GB plan for the same validity period is priced at $77.08. These fixed‑data options give a clear amount of high‑speed data and may be more cost‑effective for heavy users who do not want throttling.

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 32 single‑country data plans that cover Vietnam, along with 40 multi‑country plans that include Vietnam as part of a broader roster. The available plans span a price range from $2.13 to $1, 269.33 and offer data caps between 1 GB and 100 GB. Plans are offered in two main types: fixed‑data‑cap plans that deliver a set amount of data for the entire validity period, and daily‑data‑cap plans that limit the amount of data usable each day during the plan’s duration.
