Same-day sim replacements to a backup sim instead of waiting days for replacement sim

Chalkychap Once eSims are introduced and widespread, a lot of this won't really matter anymore, but it seems it's still in it's early stages and phone manufacturers, countries, standards and providers aren't in a rush to implement them, so for now we're stuck with the boring physical sim and the annoyances it brings (unless you have both a handset which supports eSims and a provider which also supports them, which the list of isn't very large right now).
