MobileSIM eSIM Data Plans for Vietnam

MobileSIM does not offer a true unlimited high‑speed data eSIM for Vietnam. Its “Unlimited” named plans actually provide 3GB per day of high‑speed data, after which the speed drops to 1000kbps. For travelers who need more data without the speed reduction, MobileSIM offers several fixed‑data plans. For example, Asia 100 GB for 180 days costs $185 and includes 100 GB of data usable throughout Vietnam and 17 other countries, while Asia 50 GB for 90 days costs $100. A country‑specific option is Vietnam 20 GB for 30 days priced at $30.50. Choosing one of these large fixed‑data plans can be more cost‑effective unless a user requires unlimited high‑speed data.

MobileSIM does not offer a Vietnam eSIM with a phone number that supports dial‑up calls or SMS. The available plans are data‑only and do not include telephony services.

Travelers who need to communicate while abroad can use popular VoIP and messaging apps such as WhatsApp, Telegram, or iMessage over the data connection provided by MobileSIM. These services allow voice and text messaging without requiring a local phone number or SMS capability.

MobileSIM offers 12 single‑country plans and 14 multi‑country plans for use in Vietnam. The plans span a price range of approximately $4.50 to $185, with data caps that vary from 1 GB up to 100 GB and validity periods from 3 days to 365 days. Among the offerings, six plans provide a daily data cap, allowing a fixed amount of data to be used each day, while the remaining plans feature a fixed data cap that applies for the entire validity period.
