Does the Other smartphone support eSIM in Vietnam?
Yes — if carrier-unlocked
The Other smartphone has eSIM hardware, but a unit locked to a home carrier can block a foreign eSIM until it is unlocked. If you bought it SIM-free it works out of the box; if it is carrier-locked, ask your carrier to unlock it before you travel.
Manufacturer spec: Verify in your phone's Settings menu — look for "Add eSIM" or "Add mobile plan" option.
