SimSmash eSIM Data Plans for Vietnam

SimSmash does not provide true unlimited data eSIM plans for Vietnam. All available plans have defined data caps, even the ones with “Unlimited” in the name. For example, the Vietnam Daily Unlimited 10GB/day for 1 days plan offers a 10GB data allowance that expires after one day, and the Vietnam 50GB for 180 days plan provides 50GB of data over five months.

With no unlimited option, travelers can choose a fixed‑data plan that fits their needs. A 50GB plan for 180 days, priced at $50.99, or a 20GB plan for 30 days at $14.99, are examples of larger‑capacity alternatives available. These fixed plans can be more cost‑effective for most users, while very heavy data consumers might consider stacking multiple plans or looking for higher‑cap options.

SimSmash does not provide eSIM plans with a phone number or SMS capability for Vietnam. Travelers can only purchase data‑only eSIMs, which allow Internet access for use with VoIP services such as WhatsApp, Telegram, or iMessage for voice and messaging over the data connection.

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.
