esimzon eSIM Data Plans for Vietnam

esimzon does not provide a truly unlimited data eSIM for Vietnam. The plans that carry “Unlimited” in their names are the Asia Unlimited series, which give 25 GB of high‑speed data each day. Once the daily 25 GB limit is reached, the speed is reduced to 8000 kbps, so the high‑speed data is not unlimited.

For travelers who need larger or uninterrupted data allowances, esimzon offers fixed‑data plans. For example, the Vietnam 100 GB 20Days plan delivers 100 GB of high‑speed data for 20 days, and the Vietnam 40 GB 20Days plan offers 40 GB for the same period. These fixed plans may provide a more cost‑effective option for heavy data users compared to the time‑limited “Unlimited” plans.

esimzon does not provide any eSIM plan that includes a local phone number or SMS capability for Vietnam. All of the plans sold by esimzon for this destination are data‑only.

When traveling to Vietnam, travelers can still use voice or texting through popular VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over the data connection provided by the eSIM.

esimzon presents a total of 21 data plans that can be used in Vietnam, with four single‑country options and 17 multi‑country options. The plans vary in price, from about $5 to $110, and offer data caps ranging from 1 GB to 100 GB. Some packages limit data on a daily basis while others provide a fixed amount that remains available for the entire validity period. Tethering is permitted on most of these plans, though certain options may enforce reduced speeds.
