Wiiline eSIM Data Plans for Vietnam

Wiiline does not provide a truly unlimited data eSIM for Vietnam. The plans that list “Unlimited” in the name actually offer a data cap of 1GB per day, after which the speed is reduced to 500 kbps or 0.384 kbps. Travelers who need a larger data allowance can choose from fixed‑data plans such as a 50GB plan valid for 30 days or a 100GB plan valid for 90 days, which grant full‑speed data without throttling. These options are often more cost‑effective for heavy data users.

Wiiline does not provide a Vietnam eSIM that includes a phone number or SMS capability. The provider only offers data‑only plans for travelers in Vietnam. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which allow calls and messages without a local phone number.

Wiiline offers 18 single‑country plans and 35 multi‑country plans that can be used in Vietnam. The plans span a price range from about $1.51 to $206.00 and provide data allowances between roughly 490 MB and 100 GB. Single‑country plans grant data usage solely within Vietnam, while multi‑country plans are valid in Vietnam and other destinations that the provider covers. Among the available options, some plans provide a daily data cap, meaning a set amount of data is refreshed each day, whereas other plans offer a fixed data cap, giving a single data allotment that lasts for the full validity period.
