Yeah it is great for POC. Basically something that you show as a demo and then throw it away.
I saw one mod for a Minecraft where author was honest and wrote upfront something like “please don’t report any bugs, this mod was vibe coded and I don’t have the skills to fix it”









How often you need that though? I mean ordering a SIM. And if you need it immediately you just go to one of provider’s kiosks (which is plenty of them) and you get one instantly.
As for multi sims, that’s useful especially if you travel, but on the other hand there are phones with multi SIM slots. I have one right now. The sun card slot is just longer and you can put multiple.
The whole esim reminds me when I was at Verizon when they still used CDMA. Phones didn’t have SIM and you had to call provider to make a change. So to me it feels like a step backward.
