RedSim eSIM Data Plans for Vietnam

RedSim does not offer a true unlimited data eSIM for Vietnam. All plans that include “Unlimited” in the name provide a fixed allowance of 3GB high‑speed data per day; after that, the speed drops to 1 Mbps.

The only fixed data plans that give larger totals are, for example, the Vietnam Unlimited 15‑Day plan that grants 3GB per day for 15 days and the Vietnam 20GB 30‑Day plan that offers a 20GB total. These fixed data plans are the alternatives if you need a high‑volume data allowance while traveling in Vietnam.

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 offers 36 single‑country data plans that cover Vietnam and 17 multi‑country plans that include Vietnam. The plans range in price from about $2.05 to $324.00 and provide data caps between 1 GB and 50 GB. Among the offerings, 32 plans use a daily data‑cap model—where the data allowance is reset each day—while 21 plans provide a fixed data amount for the entire validity period.
