You can continue using the same eSIM if:
- You’re in a country supported by the eSIM
- The eSIM is installed
- You buy a data top-up package or a top-up pack
If you see no options to add a top-up plan, then that eSIM is a single-use eSIM. You don’t have to delete the eSIM if you intend to use it at a later date, you can just turn it off under cellular/mobile data plans.
