Simology eSIM Data Plans for Vietnam

Simology does not provide a true unlimited data eSIM for Vietnam. Their “Unlimited” plans give 1 GB per day of high‑speed data, after which the speed drops to 1000 kbps and no further data is added within the validity window.

For travelers who need more data, Simology offers fixed data plans in Vietnam. For example, a 50 GB bundle is available for 30 days at $38.31, and a 20 GB bundle is offered for 30 days at $23.22. These fixed‑data options give a larger hard limit and may be more cost‑effective unless a traveler requires very high data consumption.

Simology does not provide eSIM plans for Vietnam that include a phone number or SMS capability. Only data‑only eSIM plans are offered for this destination.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in Vietnam before purchasing.

Simology offers 13 single‑country plans for Vietnam and 13 multi‑country plans that include Vietnam in their coverage. The plans range in price from $2.89 to $87.09, with data caps between 1 GB and 50 GB. Users can choose from daily data‑cap plans, which refresh each day, or fixed data‑amount plans that provide a set amount of data for the validity period.
