You land, the trip ends, and somewhere in your settings sits a travel eSIM you're not using any more. Delete it, or leave it sitting there? Most people assume tidying up is the responsible move, the digital equivalent of unpacking straight away. It isn't necessarily the useful one, and the honest answer depends on what you're actually optimising for.
The eSIM equivalent of a junk drawer
Unlike a physical SIM, a dormant eSIM profile doesn't cost you a drawer, a slot, or anything else scarce. It sits in your settings as a line you can switch off, using no data, costing nothing, until you either delete it or travel again.
Keeping it costs nothing
This is the part worth actually remembering: an inactive eSIM line has no ongoing charge. There's no rental fee for the unused profile, no minimum spend to keep it alive, nothing ticking over in the background. If you're likely to visit the same destination again, or you simply haven't decided, leaving it installed and switched off is the lower-effort option with no downside attached.
Frequent travellers end up with several dormant lines this way - Spain from the spring, Japan from last autumn, sitting switched off in the same settings menu as your home SIM. None of them cost anything just by existing. The only genuinely finite resource is your patience for scrolling past them when you switch lines, which is a UI annoyance, not a billing one.
