AeroSims eSIM Data Plans for Vietnam

AeroSims does not provide a truly unlimited data eSIM for Vietnam. Plans with “Vietnam Unlimited” in the name give a data cap of 3GB per day, so after the cap is reached the speed does not stay high‑speed; it is throttled. If a traveler needs higher data without limits, AeroSims offers fixed data plans, such as a 50GB plan valid for 180 days or a 20GB plan valid for 30 days, both of which give full high‑speed data throughout their validity. Choosing one of these fixed‑data options can be more cost effective for heavy data users.

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 lists 12 single‑country plans that cover only Vietnam and 21 multi‑country plans that include Vietnam. Across the catalogue the plans are priced from about $4 USD to nearly $119 USD, with data caps ranging from 3 GB to 50 GB. Some plans offer a fixed data allotment for the entire validity period, while others apply a daily data cap, which resets each day for short‑term travelers.
