Silvy eSIM Data Plans for Vietnam

Silvy does not provide any unlimited data eSIM plans for Vietnam. All of the Vietnam‑related plans that Silvy lists have a fixed data cap—ranging from 10GB to 50GB—and a specified validity period. Travelers who need more data can choose from Silvy’s fixed data plans, such as the Asia 50 GB for 180 days plan or the Vietnam (non‑HKIP) 20 GB for 30 days plan, which offer larger data allowances at a defined price. While fixed plans can be more cost‑effective for most users, they do not provide unlimited data usage.

Silvy does not offer eSIM plans for Vietnam that include a phone number or SMS capability. The provider only offers data‑only eSIM plans for this destination.

Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging, although some destinations may block or restrict specific apps or VoIP services; it is advisable to verify that the apps needed are accessible in Vietnam before purchasing.

Silvy offers six single‑country data plans that are dedicated to Vietnam. In addition, the provider has seven multi‑country eSIM plans that include Vietnam in their coverage, giving users the option to purchase a broader regional plan that also works in the country. The plans span a price range of roughly $3.90 to $95.90, a data‑cap range from 1 GB to 50 GB, and validity periods between 7 and 180 days. Some of the available plans allow tethering.
