TooSim eSIM Data Plans for Vietnam

TooSim does not offer an unlimited‑data eSIM plan for Vietnam. All of the plans listed under the provider have a fixed data allowance; the largest is a 50GB plan for 30 days that costs $119.99 USD, while a smaller 10GB plan is available for $29.99 USD.

Travelers who require more data than the fixed limits can purchase one of these higher‑cap plans, which includes tethering rights. Choosing a fixed‑cap plan can be more economical for most users unless the traveler is an extremely heavy data consumer.

TooSim does not provide an eSIM for Vietnam that includes a phone number or SMS capability. The available plans for Vietnam are data‑only, so users will not receive a local number or be able to send and receive SMS messages through the device.

Travelers who need to communicate can still use the data connection to install and use VoIP applications such as WhatsApp, Telegram, or iMessage. These apps allow calls and messaging over the Internet but do not replace a local phone number or SMS service.

TooSim offers 7 single‑country plans for Vietnam and an equal number of multi‑country plans. Prices range from about $7.99 to $138.99, data caps fall between 1 GB and 50 GB, and validity spans 7 to 30 days; many of the plans allow tethering.
