Halo eSIM eSIM Data Plans for Vietnam

Halo eSIM does not provide a truly unlimited high‑speed data eSIM for Vietnam. The plans titled “Vietnam Unlimited” give 3GB at full speed each day, after which the remaining data that day is slowed to 1 Mbps until the next day, and the plan ends after its stated validity period.

Travelers who need more data can choose one of Halo eSIM’s fixed data plans, such as a 20GB bundle for 30 days or a 10GB bundle for 30 days, both available at competitive prices and valid for a full 30‑day period. These fixed plans give a set amount of data without the daily throttle that applies to the “Unlimited” offering.

Halo eSIM does not provide a phone number or SMS capability for Vietnam. The provider offers only data‑only eSIM plans for travelers visiting Vietnam.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are available in Vietnam before purchasing a plan.

Halo eSIM offers twelve single‑country plans for Vietnam and another thirteen multi‑country options that include Vietnam. The catalog contains both daily‑cap and fixed‑data‑cap models, allowing short‑term travelers to choose a daily data limit or longer‑term visitors to opt for a set data amount. Across all plans the price range on the site is roughly $2.63 to $72.05, while data caps run from 1 GB up to 20 GB.
