nextSIM eSIM Data Plans for Vietnam

nextSIM does not provide a truly unlimited data eSIM plan for Vietnam. All plans labelled “Unlimited” in the catalogue actually include a fixed data allowance—typically 1GB for a single day or 1GB per day for multi‑day plans—and once that limit is reached the connection speed drops to a reduced rate (512 kbps or 2000 kbps).

If a traveler needs more high‑speed data, nextSIM offers fixed‑data options such as the 50 GB 30‑day plan for $41.28 USD and the 100 GB 30‑day plan for $72.64 USD, both covering Vietnam without a cap on usage length. These fixed‑data plans are generally more cost‑effective for heavy data consumers compared to the capped “Unlimited” plans.

nextSIM offers only data‑only eSIM plans for Vietnam and does not provide a local phone number or SMS capability. Travelers who need to place calls or send text messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain VoIP services, so it is advisable to confirm that the apps you rely on are accessible in Vietnam before purchasing a plan.

nextSIM offers 45 single‑country plans specifically for Vietnam and 58 multi‑country plans that include Vietnam in their coverage. The plans vary widely, with prices from $2.58 to $1, 268.60 and data caps ranging from 1 GB to 100 GB.
