Giga.Tel eSIM Data Plans for Vietnam

Giga.Tel does not provide a truly unlimited data eSIM for Vietnam. All of its so‑called “Unlimited” plans offer a fixed allowance of 1 GB per day; after this limit the data speed drops to 512 kbps. Travelers who need higher uninterrupted data volumes would need to choose from Giga.Tel’s fixed data plans. For instance, the “Vietnam Vietnamobile, 5GB /day” plan gives 5 GB per day for 20 days, and the “USA and Asia-Pacific 22 countries, 5GB” plan supplies 5 GB for 30 days. These fixed‑data options can be more economical for users who consume a lot of data but do not require a truly unlimited plan.

Giga.Tel does not offer a phone number or SMS capability for Vietnam. Only data‑only eSIM plans are available from this provider.

With a data‑only plan, travelers can still make voice calls and send messages using popular VoIP applications such as WhatsApp, Telegram or iMessage, which work over the data connection.

Ten Giga.Tel data plans cover Vietnam. Two are single‑country plans designed for users traveling within Vietnam only, while the remaining eight are multi‑country plans that include Vietnam as part of broader coverage. The provider offers both fixed data cap plans, where a set amount of data is available for the plan’s entire validity, and daily data cap plans, which allow a specified amount of data per day. Overall prices range from about USD 4.99 for the smallest 1 GB, 1‑day plan, up to USD 195.99 for the largest 5 GB, 30‑day plan. Data caps span from 1 GB to 5 GB and validity periods cover 1 to 30 days.
