eSIM Cards eSIM Data Plans for Vietnam

eSIM Cards does not provide a truly unlimited data eSIM for Vietnam. The plans that carry the “Unlimited” label actually give 2.5 GB per day for 7, 14 or 20 days, which means the total data allowance is capped at 17.5 GB for a 7‑day period, 35 GB for 14 days, and 50 GB for 20 days. Because the data cap is fixed, the plan does not offer high‑speed data without limits.

If you need more data, eSIM Cards offers fixed‑data alternatives such as the Global 100 GB plans. For example, the Global 100 GB for 5 days costs $60.17 USD and can be used in Vietnam and more than 100 other countries, while the Global 100 GB for 10 days costs $66.86 USD. These plans provide large data allowances and can be a more cost‑effective choice for heavy data users compared to the capped “Unlimited” plans.

eSIM Cards does not provide Vietnam eSIM plans that include a phone number or SMS capability. Only data‑only eSIM plans are offered for Vietnam, and travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging services.

eSIM Cards offers three single‑country data plans and two multi‑country plans for use in Vietnam. These plans include both fixed data amounts and daily data caps, providing flexibility for different usage needs. Prices range from roughly $8.02 to $66.86, while data caps vary between 2.5 GB and 100 GB over validity periods of 5 to 20 days. Some of the plans allow tethering.
