SimSmash eSIM Data Plans for Vietnam

SimSmash does not provide a truly unlimited data eSIM for Vietnam. All of its plans list a specific data cap in the Data cap column, and the name “Daily Unlimited” only denotes a set amount of data per day; after that amount the speed is reduced.

Travelers can instead choose from the fixed data plans that allow high‑speed 5G data over the country. For example, the 50GB plan valid for 180 days or the 20GB plan valid for 30 days provide large data allowances and include tethering. These options are typically more cost‑effective for most travelers unless they expect to use data above the capped amount.

SimSmash does not provide a Vietnam eSIM plan that includes a phone number or SMS capability. Only data‑only eSIMs are offered for Vietnam. Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messages. However, some destinations may block or restrict specific apps or VoIP services, so customers should confirm that the applications they rely on are available in Vietnam before purchasing.

SimSmash offers 12 single‑country data plans that cover Vietnam and 11 multi‑country plans that include Vietnam, for a total of 23 plans available to travelers. The plans vary from a modest 490 MB to a generous 50 GB of data, with prices ranging from about $1.09 up to $94.99 USD. All plans provide a fixed data allowance; some also allow tethering to other devices when the plan is activated.
