Zwitchy eSIM Data Plans for Vietnam

Zwitchy does not provide a true unlimited data eSIM for Vietnam. All plans labeled “Unlimited” actually give a fixed daily allowance (e.g., 1 GB/day or 3 GB/day) and, once that amount is used, the speed drops to 1000 kbps. Travelers who need more data without this throttle can choose from Zwitchy’s fixed data plans, such as the 50 GB / 30 days bundle for $32.00 USD or the 30 GB / 30 days bundle for $20.50 USD, both offering 5G connectivity throughout Vietnam.

Zwitchy does not offer a Vietnam eSIM plan that includes a phone number or SMS capability. The provider’s Vietnam offerings are limited to data‑only eSIMs, so travelers will not receive a local or international dialing code from Zwitchy when they purchase a Vietnamese plan.

Those who need voice or text services can rely on VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but it is important to confirm that these apps are accessible in Vietnam before traveling, as some destinations may block or restrict particular VoIP services.

Zwitchy provides 16 single‑country data plans for Vietnam and 44 multi‑country data plans that include Vietnam as part of their coverage. The plans are available in two main formats: daily data cap and fixed data amount. Daily caps offer a set amount of data that refreshes each day, while fixed data plans give you a total data allotment that lasts for the validity period. Across all plans the price ranges from about $1.00 to $140.00, and the data caps vary from 100 MB up to 50 GB, with validity periods between 1 and 30 days.
