Zwitchy eSIM Data Plans for Vietnam

Zwitchy does not provide a true unlimited data eSIM for Vietnam. All plans labeled “Unlimited” grant a daily data cap—either 1GB/day or 3GB/day for Vietnam‑specific options—after which speed is reduced to 1000 kbps. For travelers who need large amounts of high‑speed data, Zwitchy offers fixed‑cap alternatives such as the 50 GB plan for 30 days, priced at $32.50 USD, or a 30 GB plan for 30 days, priced at $20.50 USD. These fixed options deliver more data for a longer period without the speed throttling that applies to the “Unlimited” plans.

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.
