Simsima eSIM Data Plans for Vietnam

Simsima does not provide a truly unlimited data eSIM for Vietnam. The plans that carry the word “Unlimited” in their names offer only 3GB of high‑speed data per day; after that quota the network speed drops to 1000kbps. For travelers who need higher data volumes, Simsima offers fixed data plans such as the 20GB 30‑day bundle or the 10GB 30‑day bundle, both of which provide a larger amount of 5G data without a daily limit. These alternatives are often more cost‑effective for users who require substantial data but are not extreme heavy‑data consumers.

Simsima does not provide eSIM plans with a phone number or SMS capability for Vietnam; all of its offerings for the country are data‑only. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection, but it is advisable to confirm that these services are accessible in Vietnam before purchasing, as some destinations may restrict or block certain apps.

Simsima lists 11 single‑country data plans that cover Vietnam only, and an additional 9 multi‑country plans that include Vietnam as part of a broader regional offering. The available plans vary in price from about $1.50 to $84.83, with data caps ranging from 100 MB up to 20 GB. Some of these plans provide a fixed amount of data that remains usable for the entire validity period, while others employ a daily data cap, allocating a set amount of data each day during the plan’s lifespan.
