Does the Xiaomi 11 / 11 Ultra support eSIM in Vietnam?
Depends on where it was bought
Most Xiaomi 11 / 11 Ultra units support eSIM — but the version sold in mainland China, Hong Kong and Macau usually ships with dual physical SIM and NO eSIM. Units from the US, Europe, Vietnam and most other regions do have eSIM. To check your own: open Settings → General → About and look for an EID number — if it is there, your Xiaomi 11 / 11 Ultra supports eSIM.
