nextSIM eSIM Data Plans for Vietnam

nextSIM does not provide a true unlimited high‑speed data eSIM for Vietnam. All plans labeled “Unlimited” give a fixed amount of data—typically 1 GB per day or 2 GB per day—and once that limit is reached the speed is throttled to 512 kbps or 2000 kbps.

Travelers who need more data can choose from nextSIM’s fixed‑data plans, such as 100 GB for 30 days or 50 GB for 30 days, which offer full high‑speed data until the allotted amount is used. These options can be more cost effective for heavy data users than 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 provides a range of data plans that include Vietnam as a single‑country option and also as part of its multi‑country bundles. In total, the catalogue lists 60 single‑country plans and 58 multi‑country plans that can be used in Vietnam. Among these, 38 plans use a daily data cap, allowing the user to purchase a certain amount of data per day, while 80 plans use a fixed data cap, where a set amount of data is supplied for the entire validity period. Prices for the plans span from as low as $1.97 up to $1, 254.09, and data allowances cover 1 GB to 100 GB with validity periods ranging from a single day to one year, giving travelers a wide range of options for their stay.
