Saily eSIM Data Plans for Vietnam

Saily does not have a high‑speed data plan that is truly unlimited for Vietnam. Every plan listed by Saily for the country has a hard cap, after which the connection speed is throttled to a very low rate.

Travelers who need substantial data can select from Saily’s fixed‑data bundles. For example, a 5 GB per day plan that lasts 30 days costs $71.99, while a smaller 20 GB bundle for 30 days is available for $28.99. Both plans cover the entire country of Vietnam.

Saily does not provide any Vietnam eSIM that includes a phone number or SMS capability. Travelers who need local calling or SMS services will need to rely on alternative solutions. The Saily Vietnam eSIMs are data‑only plans, so they can be used with VoIP applications such as WhatsApp, Telegram or iMessage for voice and text. However, some destinations may block or restrict certain VoIP services, so travelers should verify that the apps they plan to use are accessible in Vietnam before purchasing a data plan.

Saily provides 11 single‑country data plans for Vietnam and 22 multi‑country plans that include Vietnam as one of the covered destinations. The available plans range in price from $3.99 to $159.99 and offer data caps from 1 GB up to 30 GB with validity periods of 5 to 365 days, allowing customers to choose between fixed data amounts and daily capped data depending on the selected plan.
