nextSIM offers a total of 29 single‑country plans and 34 multination‑country plans that include Vietnam. The single‑country offerings provide only local data service for Vietnam, while the multination plans bundle Vietnam with other destinations.
The plans span a price range from17 up to $1,299.53 and a data cap range of 1 GB to 50 GB, with validity periods between 1 and 30 days.
Among the plans, 24 are structured as daily data cap packages, meaning the data allowance refreshes each day of the validity period, whereas 39 are fixed‑data‑cap plans that provide a one‑time data allotment that does not reset daily. Both types are available to suit different usage patterns.
