They are incredibly handy when you are traveling abroad, you don't speak the local language fluently, you want cheap data, you don't want to study 100 different prepaid plans from 10 different local primary and MVNO carriers to figure out the best offer, you don't want to wait for the shops to open because your flight landed late at night, and you don't want to scan your passport and send it to the carrier for verification and wait for hours for approval (yes, in many countries, KYC is required even for prepaid SIMs). I've lived that experience and I can't say I miss it.
Yeah, basically people here think that their experience is the only experience there is with phones. I wager not that many people are actually physically going to stores in many markets anymore like this commenter, and definitely next to nobody is switching their SIM cards literally every month like a sibling commenter is doing, but for people like me who live and travel abroad, eSIMs have been great.
