nextSIM eSIM Data Plans for Vietnam

No, nextSIM does not provide an unlimited high‑speed data eSIM for Vietnam. The plans that carry “Unlimited” in their name actually give a capped amount of high‑speed data—either 1GB or 2GB per day—and the speed drops to a reduced rate (512kbps or 2000kbps) once that limit is reached. Therefore an unlimited plan is not available.

NextSIM offers fixed data options that may suit heavy‑usage travelers, such as the 100GB 30 days plan at $72.64 USD or the 50GB 30 days plan at $41.29 USD, and a 50GB 60 days plan at $71.21 USD. These plans provide a larger, consistent data allowance and can be more cost‑effective for users who anticipate substantial data consumption.

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 lists 60 single‑country plans and 62 multi‑country plans that cover Vietnam. The catalog includes both daily data cap options (38 plans) and fixed data amount plans (84 plans). Prices span from about $2.09 up to $1, 264.89, while the data allowances range from 1 GB to 100 GB. Validity periods also cover days from 1 to 365, giving travelers a broad range of options for staying connected in Vietnam.
