Does KnowRoaming offer unlimited data eSIM for Vietnam?
KnowRoaming does not provide an unlimited data eSIM plan for Vietnam. Travelers looking for high data volumes can choose from fixed‑data options such as the 100GB 180‑day plan priced at $180.00 USD or the 50GB 60‑day plan at $99.00 USD. These plans give ample data for most users and may be more cost‑effective than paying for individual data bundles if you expect to use a lot of data. For those who use data sparingly, smaller packages like the 20GB 30‑day plans are also available.
Does KnowRoaming offer Vietnam eSIM with phone number and SMS?
KnowRoaming does not provide a Vietnam eSIM that includes a local phone number or SMS capability. Only data‑only eSIM plans are available for travelers visiting Vietnam. Travelers can still use VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging.
How many data plans does KnowRoaming offer for Vietnam?
KnowRoaming offers five single‑country plans and twelve multi‑country plans for Vietnam. Prices range from about $3.89 to $180, with data caps from 1 GB to 100 GB and validity periods between 7 and 180 days. Single‑country plans provide data only in Vietnam, while multi‑country packages allow usage across a broader set of destinations with a shared data allowance.
