eSIMCard eSIM Data Plans for Vietnam

eSIMCard does not provide a truly unlimited data eSIM for Vietnam. All plans labelled “Unlimited” in the name actually include a fixed data cap, such as 1GB or 2GB per day, and specify a reduced speed once that limit is reached. Travelers can instead choose from fixed‑data alternatives; the catalogue contains a 1GB per day option for a single day, 1GB per day for up to 30 days, and a 100 GB plan that is valid for 30 to 180 days. These fixed‑data plans offer a clear, predictable data allowance without the throttling that accompanies the “Unlimited”‑named plans.

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 provides 31 single‑country plans and 99 multi‑country plans that include coverage in Vietnam. The cost of these plans ranges from $2.88 to $395.07, while the data limits vary between 1 GB and 100 GB. Plans are offered in two main styles: fixed data plans, which grant a set amount of data for the duration of the validity period, and daily‑cap plans, which allow a maximum amount of data each day during the plan’s active window. This gives travelers numerous options in terms of budget, data volume, and coverage flexibility.
