I had eSIMs get screwed up on my iPhone a year or two ago when I deleted an expired eSIM. It asked me "Do you want to update contacts to use <the SIM I just deleted>?" and I knew I was in trouble.

I did successfully use a backup editor, iMazing, to exclude the telephony data from a backup in order to fix it, but it cost me $30 and hours (transferring my Signal data to a second device and back). For 99.999% of their customers this would require a total erase-install. All because Apple has an off-by-one error somewhere.
