This can be done with physical+esim, which my iPhone SE3 has.
Is there a distinct advantage to eSIM-only, with no physical slot, for travel?
> - You can have multiple esimss. With physical sims you are limited to the physical number of sim slots on your phone, usually 1 or at most 2. With esim there is no such restriction.
If you already have 1-eSIM capability, would it be hard to go to >1-eSIM+physical?
