eSIMCard eSIM Data Plans for Vietnam

eSIMCard does not provide a true unlimited data eSIM for Vietnam. All plans that contain “Unlimited” in the name are actually limited to a fixed amount of high‑speed data—typically 1GB per day or 2GB per day—after which the speed is throttled to 512kbps or 2000kbps, respectively.

For travelers who need more data, eSIMCard offers fixed‑amount plans such as a 100GB eSIM valid for 30 days or 180 days, which deliver full high‑speed connectivity throughout Vietnam without the speed reduction that applies to the “Unlimited” packages. These fixed‑data options tend to be more cost‑effective for users who consume a large amount of data.

eSIMCard does not provide a Vietnam eSIM that includes a phone number or SMS capability. The provider’s plans for Vietnam are limited to data‑only eSIMs, so no inbound or outbound voice or text services are supported.

Guests traveling to Vietnam can still communicate using data‑based tools such as WhatsApp, Telegram and iMessage, which allow voice and text messaging without a local phone number.

eSIMCard offers 31 single‑country data plans and 97 multi‑country data plans for Vietnam. The plans available range in price from roughly $2.88 to $395.07 and in data cap from 1 GB to 100 GB. The provider provides two main types of plans: fixed data cap plans, which give a predetermined amount of data for the entire validity period, and daily data cap plans, which cap the amount of data you can use each day during the plan’s validity.
