eSIM Cards eSIM Data Plans for Vietnam

eSIM Cards does not provide a truly unlimited data eSIM for Vietnam. The plans that carry the name “Vietnam Unlimited eSIM” actually give 2.5GB of high‑speed data per day and then throttle to a reduced speed; they are not unlimited in the sense of offering high‑speed data without limits.

Travelers who need a large amount of data can choose from fixed data plans that offer high‑speed data for a set validity period. Examples include the Vietnam 10GB Travel eSIM for 30 days and the Global 100GB plans for 5 or 10 days, which provide a generous data allowance at 5G/4G LTE speeds during the plan’s validity. These fixed plans can be more cost‑effective unless a user requires very heavy data usage.

eSIM Cards 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. Users who need voice or messaging can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Vietnam before purchasing, as some destinations may block or restrict certain apps.

eSIM Cards offers 7 single‑country plans that cover Vietnam and 3 multi‑country plans that include the country. Seven of the plans provide a fixed data amount between 1 GB and 100 GB, while the remaining three feature a daily data cap. Prices range from roughly $3.90 to $68.28, and validity periods span 5 to 30 days. Tethering is allowed on some of the plans.
