nextSIM eSIM Data Plans for Vietnam

nextSIM does not offer a true unlimited high‑speed data eSIM for Vietnam. All plans that carry “Unlimited” in the title actually provide a fixed data allowance; after that amount is used the speed is throttled to a reduced rate such as 512 kbps or 2000 kbps.

Travelers who need more data can choose from a range of high‑cap fixed plans, for example the eSIM Vietnam Unlimited Plus 10Days Standard, which gives 2 GB per day for 10 days, or the eSIM Vietnam 100GB 30Days Standard plan that provides 100 GB for a month. Choosing a fixed data plan is typically more cost‑effective unless a user expects very heavy 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.
