The eSIM stops carrying data. Nothing is charged after that, and nothing renews by itself.
Some eSIMs can have more added to them — more days on an unlimited plan, more data on a fixed-data one. Your order page shows what your own network will accept.
Where nothing can be added, buying again is the way to carry on. That is a new eSIM to install.
Sometimes. Your order page lists what the network behind your own eSIM will accept, under "Add more to this eSIM". On an unlimited plan that is more days; on a fixed-data plan, more data.
It goes onto the eSIM already in your phone, so there is nothing new to install.
If the list is empty, this eSIM cannot be extended and a fresh plan is the way on. If the network turns a top-up down, you are not charged and we say so.
No. There is no subscription and nothing renews by itself. You pay once for a plan and that is the end of it.
Nothing is stored to charge you again, and there is no membership to cancel.
If you want more days, you add them or buy again, deliberately.
No, and while the plan is still running you should not. A deleted eSIM cannot be brought back and what is left on it is gone.
Once the plan has ended the line is harmless. You can switch it off and leave it, or remove it if you want the space.
What you should do on the way home is set mobile data back to your own line.
