Does your phone support eSIM?
Start typing your model — if it is in the list, an eSIM will work. The phone also needs to be carrier-unlocked.
Important: the list is a guide. eSIM may be disabled on carrier-locked phones and on some region variants — notably iPhones bought in mainland China (they use two physical SIMs instead).
The surest check: open Settings and look for “Add eSIM” / “Add cellular plan”. If it is there — you are good.
