MyTravel eSIM does not offer an eSIM plan for Vietnam that includes a phone number or SMS capability. The provider only sells data‑only eSIMs for that destination.
Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages, but availability of these services can sometimes be restricted in Vietnam. It is advisable to verify the functionality of the required apps before purchasing a plan.
