Flysimio eSIM Data Plans for Vietnam

For travelers who need strong data coverage without a hard limit, Flysimio offers fixed‑data plans such as the 50 GB 180‑day plan priced at 109.20 USD and the 20 GB 30‑day plan priced at 31.58 USD. These fixed data bundles are typically more cost‑effective for moderate data usage and support 5G connectivity in Vietnam.

Flysimio does not provide an eSIM for Vietnam that includes a local phone number or SMS capability. The provider only offers data‑only plans for travelers in Vietnam. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Vietnam before purchasing, as some destinations may block or restrict certain apps.
