nextSIM eSIM Data Plans for Vietnam

nextSIM does not offer plans that provide truly unlimited high‑speed data in Vietnam. The packages labeled “Unlimited” actually grant either 1GB or 2GB of unrestricted data per day; once this amount is reached, the speed drops to a reduced level of 512kbps or 2000kbps. For travelers who anticipate using more data, nextSIM provides fixed‑data options such as the 100GB 30‑day plan or the 50GB 30‑day plan, which give larger data allowances at a predictable cost. These fixed‑data plans can be more economical and suitable for heavy data usage compared to the capped “Unlimited” offers.

nextSIM does not offer an eSIM plan for Vietnam that includes a local phone number or SMS capability. Their Vietnam plans are strictly data‑only, allowing travelers to use the data allowance for internet access via 5G, 4G, or 3G depending on coverage.

Travelers who need voice or text can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, as these apps do not require a traditional phone number or SMS service.

nextSIM offers a total of 34 single‑country data plans for Vietnam and an additional 40 multi‑country plans that can be used in Vietnam. The plans span a price range from about $3.17 to $1,281.07 and data caps between 1 GB and 100 GB, with validity periods of 1 to 30 days. They are distributed in two main types: daily‑cap plans, which provide a fixed amount of data each day of the validity, and fixed‑cap plans, which give a total data allowance for the entire validity period.
