AeroSims eSIM Data Plans for Vietnam

AeroSims does not provide a truly unlimited data eSIM for Vietnam. The plans that carry the name “Vietnam Unlimited” actually give 3GB of high‑speed data each day and then throttle the connection to 1000kbps once that daily limit is reached, so they are not unlimited.

Instead, AeroSims offers fixed data plans that give a set amount of high‑speed data for a specified validity period. Examples include the Phu Quoc 50GB plan valid for 180 days, the Asia (7 Countries) 50GB plan also valid for 180 days, and the Phu Quoc 20GB plan valid for 30 days. These fixed data plans can be more cost‑effective for most travelers unless the user is an extremely heavy data consumer.

AeroSims does not offer eSIM plans that provide a phone number or SMS capability for Vietnam. The provider only supplies data‑only eSIMs for that destination. Travelers can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging, but they should verify that these services are accessible in Vietnam before purchasing an eSIM.

AeroSims provides 12 single‑country data plans that cover Vietnam, alongside 21 multi‑country plans that include Vietnam as one of their destinations. Plan prices vary from about $3.96 to $118.67, while data caps range between 3 GB and 50 GB. The catalogue features both fixed‑data‑cap options and a smaller set of daily‑data‑cap plans, allowing travelers to choose either a dedicated amount of data for their entire stay or a per‑day data allowance.
