RedSim eSIM Data Plans for Vietnam

RedSim does not offer a truly unlimited data eSIM for Vietnam. The plans that use the word “Unlimited” give 3 GB of high‑speed data per day and reduce the speed to 1000 kbps after that limit is reached. If you need a larger data supply, RedSim provides fixed data plans such as Vietnam Unlimited 15 Days, which offers 3 GB/day for 15 days, or Asia 50GB 30 Days, which provides 50 GB for 30 days.

RedSim does not offer a Vietnam eSIM that includes a phone number or SMS capability. The provider’s offerings for Vietnam are limited to data‑only eSIM plans, and the dataset indicates that no telephony‑enabled plans exist for this destination.

Travelers who require voice or messaging can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but accessibility of these apps can vary in Vietnam, so it is advisable to confirm that the services you rely on are available before purchasing.

RedSim provides 21 single‐country data plans that are valid only within Vietnam, while 17 multi‑country plans are available that include Vietnam as part of a broader coverage. The single‑country offerings vary from as little as 1 GB to 50 GB of data with prices ranging from $1.84 to $73.36, and plan durations from 1 to 30 days. The multi‑country set follows a similar pricing and data spectrum, though the data caps may be adjusted to accommodate combined usage across several destinations. Some plans are structured with a fixed data allotment, while others apply a daily data cap that resets each day. The overall range of data caps available across both types of plans spans from 1 GB up to 50 GB, giving travelers a wide selection depending on their usage needs.
