What's the point of sim cards anyways? I'm not sure why it's needed when things can be done over software. It feels like an antiquated piece of technology. Like just use the phone identifier or something, and map it to a digital sim.
- nottorp 6y agoIt decouples the carrier from the phone manufacturer. I'd rather swap sims than beg Apple to change my carrier. Maybe to one they don't yet support. Of course, you need an unlocked phone for this, but in the poorer countries most people are on prepaid not contract, and their phones are unlocked from the start.

- nottorp 6y ago> The obvious solution is that sim is replaced with a username and password That would still go through the phone manufacturer? Or maybe not, but in that case it would require changing how all the cell phone networks work. Not going to happen soon.
- Polylactic_acid 6y agoI have wondered the same thing. I just did a search and all I can find is uninformed speculation about how its "more secure" or because its required as part of the mobile technology. None of it seems correct and my guess is there is just no push for esim because every phone has to have a sim tray for compatibility and every carrier gives out a sim because everyone has a sim tray and knows how to use it.
